No the atmosphere does not allow heat to escape quickly to cool the planet
Atmospheric pressure is an important factor in keeping liquid water on the surface of a planet. With no atmosphere, liquid water would quickly escape into space. It would depend on various factors such as the temperature and escape velocity of the planet of course. Scientists think liquid water existed on Mars in the past when the atmosphere was a lot denser. Water does exist on the surface Mars, but only as ice.
to allow breathing and expiration of those mixtures necessary for life of all denizens of that planet
They're commonly called 'greenhouse gasses'.
biotonic gas
It is still thick enough to allow for immense dust storms to exist.
Gases in the atmosphere, like carbon dioxide and water vapor, trap heat from the sun in a process known as the greenhouse effect. These gases allow sunlight to enter the Earth's atmosphere and warm the planet, but trap some of the heat that would otherwise escape back into space. This helps maintain the Earth's temperature at a level suitable for life.
Jupiter has more hydrogen and helium gas because it has more gravitational pull than any other planet so it pulls almost every gas with a greater efficiency and does not allow to escape from its atmosphere,as in the case of earth gases like (hydrogen) tends to escape easily.
Earth is the planet that has water, oxygen, and regulated temperatures that can support life as we know it. Its atmosphere and location within the habitable zone allow for these conditions to exist.
Greenhouse gases, such as carbon dioxide and methane, get trapped by the Earth's atmosphere. These gases allow sunlight to enter the atmosphere and warm the planet, but then trap some of the heat that would otherwise escape into space. This process helps regulate Earth's temperature, keeping it within a range that is suitable for supporting life.
Any suddenly opening appearing in the skin of the spacecraft would allow the atmosphere inside the craft to escape out into space - causing decompression.
the chip escape route
The continuous movement of water molecules can lead some molecules at the surface to escape in the atmosphere as a gas. High temperature and low pressure favors evaporation.
