Summary

The greenhouse theory teaches us that gases such as CO2, take thermal radiation from the earth's surface of 255 kelvin or -18° C and re-emit it to 288 kelvin or 15°C, an increase of 33°C, This effect of increasing the heat absorbed by CO2 is known as the greenhouse effect, so to lower the temperature of the planet, it is necessary to decrease these gases in the atmosphere, but these claims are contrary to the specific heat capacity of CO2 molecules, this work shows that CO2 needs to absorb heat of 3°C to produce 1°C. that is, CO2 reduces the heat absorbed by 1/3. So it can be concluded that, contrary to the theory of the greenhouse effect, it is necessary to increase the CO2 in the atmosphere to reduce the temperature of the planet by 1/3. We can see it in real life, in the industry the technique known as oxy-combustion, uses oxygen gas to increase the temperature in an oven, and uses CO2 gas to reduce the heat of the oven.

Introduction;

Today there is talk that global warming can be stopped if the gases that retain heat in the atmosphere are decreased, these gases are known as greenhouse gases, this idea is based on the theory of the greenhouse effect, which teaches us, that the gases that strongly trap heat increase the temperature of the planet, but physics teaches us, that heat is a transfer of energy from hotter to colder systems that are in contact, and the fact that CO2 catches heat, what it means is that much more heat is needed to heat CO2, the opposite of any other molecule in the air that does not catch heat,  therefore it can be understood that this effect of increasing heat, because it is trapped by gases like CO2, it does not exist, before is the opposite.We can see it in real life, in the industry the technique known as oxy combustion, uses oxygen to heat a oven up to 3000 ° C, and uses CO2 to reduce the heat of the oven.

Scientific theory:

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).1

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, resulting in an increase in the average surface temperature compared to what would be in the absence of GHGs.2

One part of the solar radiation that reaches Earth passes through the atmosphere, is reflected back into space; another reaches the ground and warms it. It emits heat (infrared radiation) and warms the atmosphere, since the heat is retained by the greenhouse gases.3

Without this natural greenhouse effect, the equilibrium temperature of the Earth would be about -18 °C. However, the average temperature of the earth's surface is about 14 °C, a difference close to 32 °C that gives us an idea of the magnitude of efecto.4

Temperature is a measure of the average kinetic energy of the atoms or molecules in the system.5

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, end the mass of the substance m, and the change in temperature ΔT, end text in the equation:  q=m×C×ΔT.  6

Specific Heat: The amount of heat needed to raise the temperature of 1kg of a substance by 1°C.7

In industry CO2 as a heat reducer.

Oxy-combustion; it is a technique that consists in separating the nitrogen of the atmosphere of an oven, and replace it with pure oxygen, which increases the temperature. When the temperature is 3000°C by the injection of pure oxygen, then is recirculated the CO2 produced by the oven to reduce the temperature, which lowers the temperature of the oven until the 1900°C.8

Results;

Physics teaches us that; "Heat is thermal energy transferred from a hotter system to a cooler system that is in contact," and "We can calculate the heat released or absorbed using the specific heat capacity, the mass of the substance, and the temperature change in the equation": Q=M×C×ΔT.

Q = heat released or absorbed

m = mass of the substance

C = Specific heat; this is the amount of heat needed by one gram of a substance to raise its temperature by 1°C.

ΔT= Temperature change

What amount of heat must the earth's surface emit to CO2 in the atmosphere to raise its temperature from 287 kelvin or 14°C to 288 kelvin or 15°C?

 

C=Specific heat (CO2)=836 J/Kg°C

Ti= Initial temperature=287k or 14°C

Tf= Final temperature=288k or 15°C

M= mass of CO2= 0.044 Kg

Q=?

Equation; Q=m×C×ΔT.

Solution; Q= (0.044 Kg) x (836 J/Kg°C) x (288 k or15°C- 287 k or 14°C)

  Q= (0.044 Kg) x (836 J/Kg°C) x (1°C)

  Q= (0.044) x (836 J) x (1)

 Q= 36.784 J

The amount of heat needed by the earth's surface for CO2 to rise from 287 kelvin or 14°C to 288 kelvin or 15°C is 36,784 Joules.

Now we will convert joules into kelvin degrees based on the following;

Of the two expressions for the pressure of a gas, one derived from macroscopic experimental data, P · V = k · T and another derivative of 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, that is, the temperature of a gas is proportional to the average kinetic energy of its molecules.

T = 2 / (3k) · m · (v2) pr / 2

T = 2 / (3R 8, 31 J / mol .k) Kinetic Energy = 36.784 J

T = (0,0802246289610911 J / mol .k). 36.784 J

T = (0, 0802246289610911 k). 36.784

T = 2.95 Kelvin

36.784 joules equals 2.95 kelvin of temperature. So we can say that for every 3 degrees of heat absorbed by CO2 in the atmosphere, it emits 1 degree of heat in all directions, a 1/3 decrease in the trapped heat.

Conclusion

To say that the ability to trap heat by certain gases decreases the temperature is logical, and we can see it in oxy-combustion (furnaces heated with oxygen and cooled with CO2), but it can also be demonstrated with the laws of thermodynamic physics, based on the caloric capacity of CO2, it can be concluded, that for every 3 degrees of heat emitted by any heat source, that is absorbed or trapped by CO2 molecules, it emits in all directions 1 degree of temperature, decreasing the heat by a third, so the theory of the greenhouse effect that teaches that CO2 increases the temperature on the planet, is contrary to nature or the specific heat of CO2.
