What is the greenhouse effect? Author; Rogelio Pérez C Summary The temperature of the planet is associated with a greenhouse effect, by certain gases in the atmosphere known as greenhouse gases, some of the main gases being CO2 and Methane. This work explains that the greenhouse effect is a pressure effect on gases, which happens in a closed place. When in a closed place like a greenhouse, light energy is allowed in either the sun or artificial, this energy causes an effect of raising the temperature inside this closed place, because light energy increases the speed of gas molecules that are contained within this, because these molecules hit more frequently and with more force over the walls, which is why it is concluded, that a greenhouse does not retain heat, but the gas molecules that transfer heat with shocks. This explanation was said by the Frenchman Gay-Lussac in the early 1800s, to explain the relationship between temperature and pressure of a gas, now, as the ...
