The temperature originates only from the kinetic energy, from the gas molecules in the atmosphere.
Author; Rogelio Pérez C
Summary;
Temperature is defined by physics, as a measure of the
average speed at which atoms and molecules move in systems. This work will
therefore explain the temperature, pressure, kinetic energy and the speed at
which molecules move in gases known as the atmospheres on three planets of the
solar system, based on the kinetic theory of gases, I will show through the
mathematical formulas of kinetic energy, that temperature, and pressure is
proportional to the average energy of gas molecules in the atmospheres on
planets, earth, Venus and mars. That's why it's false that the heat on the
planet correlates with as few molecules in the atmosphere, like CO2, which are
only 0.04% of the total molecules in it.
Therefore, the explanation of global warming must consider kinetic energy, in
order to understand how heat affects, not only on planet earth, but on every
planet in the solar system.
Introduction
Rising temperatures on the planet are being the global
problem on which countries are spending enormous resources, some have begun to
give voices of panic, about the consequences that the planet can raise the
temperature in such a way that it is impossible to live on it. To know the
possibility of catastrophic events due to the increase in temperature of the
atmosphere, we need to know what says the science of gases, about the
temperature of the main gas that surrounds planets called atmospheres. Climate
science teaches us based on a theory of more than 100 years, that temperature
on the planet is caused by the accumulation of heat, which certain gases known
as GHG do in the atmosphere, but there is an older science that explains the
temperature of gases, which has been ignored to explain the temperature in the
atmospheres of the planets, so based on this I will explain how temperature and
pressure originate in gases.
Theory statement and
definitions
The greenhouse
effect theory
The greenhouse
effect is a process in which thermal radiation emitted by the planetary surface
is absorbed by atmospheric greenhouse gases (GHGs) and radiated in all
directions. As part of this radiation is returned to the Earth's surface and
lower atmosphere.1
Kinetic of
gases theory
The kinetic of gases theory is a physical and chemical theory that explains the macroscopic behavior and properties of gases (the law of ideal gases), based on a statistical description of microscopic molecular processes. The kinetic theory was developed based on studies by physicists such as Daniel Bernoulli in the 18th century, Ludwig Boltzmann and James Clerk Maxwell in the late 19th century.2
Charles law for
gases, for any gas, the ratio between temperature and
volume is directly proportional, if the quantity of gas and pressure remain
constant.
Mathematically
we can express it like this:
V is the volume
T is the
absolute temperature (i.e measured in kelvin).
k is the
constant of proportionality.3
Heat, q, is
thermal energy transferred from a hotter system to a cooler system that are in
contact. Temperature is a measure of the average kinetic energy of the atoms or
molecules in the system. The zeroth law of thermodynamics says that no heat is
transferred between two objects in thermal equilibrium; therefore, they are the
same temperature.4
Heat, is
thermal energy transferred from a hotter system to a cooler system that are in
contact.
We can
calculate the heat released or absorbed using the specific heat capacity C, the
mass of the substance, m, and the change in temperature, ΔT in the
equation: q=m×C×ΔT
Heat and
temperature are two different but closely related concepts. Note that they have
different units: temperature typically has units of degrees Celsius (degrees
°C,) or Kelvin (K), and heat has units of energy, Joules (J).
Temperature is
a measure of the average kinetic energy of the atoms or molecules in the
system. The water molecules in a cup of hot coffee have a higher average
kinetic energy than the water molecules in a cup of iced tea, which also means
they are moving at a higher velocity.5
Temperature is
also an intensive property, which means that the temperature doesn't change no
matter how much of a substance you have (as long as it is all at the same
temperature!). This is why chemists can use the melting point to help identify
a pure substance—minus the temperature at which it melts is a property of the
substance with no dependence on the mass of a sample.
The
equipartition theorem relates the temperature of a system to its average
energies. It makes quantitative predictions, provides the total kinetic and
potential energies for a system at a given temperature, from which the heat
capacity of the system can be calculated. However, the equipartition also
provides the average values of individual energy components, such as the
kinetic energy of a particular particle or the potential energy of a single
spring. For example, it predicts that each atom in an ideal monoatomic gas has
an average kinetic energy of (3/2) k B T in thermal equilibrium, where k B is
Boltzmann's constant and Te the temperature (thermodynamics).6
Thermal motion of an α-helical peptide. The jittery motion is random and complex and the energy of any particular atom can fluctuate wildly. Nevertheless, the equipartition theorem allows the average kinetic energy of each atom to be computed, as well as the average potential energies of many vibrational modes. The grey, red and blue spheres represent atoms of carbon, oxygen and nitrogen, respectively; the smaller white spheres represent atoms of hydrogen.7
The mole
(symbol: mole) is the unit with which the amount of substance is measured, one
of the seven fundamental physical magnitudes of the International System of
Units.
In any
substance (chemical element or compound) and considering at the same time a
certain type of elemental entities that make up it, the mole, mole symbol, is
the SI unit of quantity of substance. A mole contains exactly 6,022 140 76 ×
10–23 elemental entities.8
Kinetic energy
is the energy of a moving body. Kinetic energy is defined as the work to be
done by the force it exerts on the resting body to accelerate it.9
Applying Newton's mechanics
concludes, for the three dimensions of the movement, that the P pressure is
related to the average velocity of the squared atoms, (v2)pr, and to the
volume, V, and mass of the gas molecule, m, according to the expression. , P =
m· (v2)pr / 3V
A derivative of macroscopic
experimental data, P. V 'k' T and another derivative of Newton's laws applied
to our simple model, P = m· (v2)pr / 3V. If both describe the same reality,
Then it should happen that k · T = m · (v2)pr / 3. It follows that the
temperature, T = 2/(3k) · m ·(v2)pr /2, i.e. the temperature of a gas is
proportional to the average kinetic energy of its molecules.10

“If you can measure what you are
talking about, and if you can express it by a number, then you may think you
know something; but if you can't measure it, your knowledge will be poor and
unsatisfactory”
Lord Kelvin
Development
First we will find the average quadratic velocity of
the molecules in a gas mole, this means that we will find the average of the
squared velocity, at which the molecules move, at different temperatures.
The quadratic velocity for a mole of
nitrogen gas in the Earth, we take Nitrogen because it is
equivalent to 78% of all molecules in the atmosphere.

0.028=506.38 m/s
Then we find the average quadratic velocity, we can
find the kinetic energy that molecules originate in this gas mole. Don't forget
that the temperature of any system is the measure of this average.
Kinetic energy
is a form of energy, known as motion energy. The kinetic energy of an object is
the energy produced by its mass-dependant movements and speed of the same.
Kinetic energy is usually abbreviated by the letters "EC" or
"Ek". The word kinetics is of Greek origin “kinesis” meaning
“movement”.
Kinetic energy is represented by the following
formula: EC or Ek=½ mv². Kinetic energy is measured in Joules (J), mass in
kilograms (kg) and velocity in meters over seconds (m/s).4
The kinetic energy
for a mole of nitrogen gas on Earth is;
Ec or Ek. Nitrogen:
M= 0.028kg/mole
Vcm= 506.38m/s
Ec= ½ 0.028kg/ mole

Ec or Ek=3589.89 J
The kinetic energy
(E) of a body with mass m = 0.028 kilograms and velocity v = 506.38 m/s equals 3589.89 J
Then since we have the kinetic energy, let us find
what the temperature of each measure of kinetic energy, found in the gases.
Of the two expressions for the pressure of a gas, one
derivative of macroscopic experimental data, P· V = k ·T and other derived from
Newton's laws, P = m*(v2)pr / 3V. If both describe the same reality, then it
should happen that k·T = m*(v2)pr / 3. It follows that the temperature, T =
2/(3K)*m*(v2)pr /2, i.e. the temperature of a gas is proportional to the
average kinetic energy of its molecules.

Conclusión;
In this work we conclude that temperature and pressure
in the atmospheres of the solar system, is a consequence of the kinetic
movement of all gas molecules in these, and not as a result of the retention or
absorption of heat of certain traces of gases in the atmosphere, known as
greenhouse gases. At the time if the temperature is a consequence of the
movement of the gas molecules, then the increase in temperature is a
consequence of the increase in the speeds of the molecules.
Finally, the kinetic energy of the gases not only
explains the temperature and pressure variables perfectly, but it is the only
science that explains the temperature of the gases, besides the atmosphere is a gas, and temperature is
kinetic energy.
