Question

Why does water vapour play a role in heating and cooling the atmosphere?

Answer 1

Hint: An atmosphere is a layer of gas that surrounds a planet and is kept in place by the planetary body's gravity. When the gravity is high and the temperature of the atmosphere is low, a planet keeps its atmosphere.

Complete answer:
The gaseous phase of water is known as water vapour. Within the hydrosphere, it is one type of water condition. Evaporation or boiling of liquid water, as well as sublimation of ice, can generate water vapour. Water vapour, like the majority of atmospheric components, is transparent. Water vapour is continually produced by evaporation and eliminated by condensation under normal atmospheric conditions. Its density is lower than that of most other air components, causing convection currents that can lead to clouds.
As water vapour molecules develop, they absorb heat as the temperature rises. When they condense, the latent heat is released into the atmosphere. As a result, water vapour is vital in both heating and cooling the atmosphere.
Water vapour is one of the most changeable gases in the atmosphere, and while it is only present in minute amounts, it is extremely essential. Water vapour is an important component of the atmosphere's insulating properties. The ability of air to contain moisture changes in direct proportion to its temperature. In other words, the more the capacity to store moisture, the higher the temperature of the air, and vice versa.

Note:
Water vapour is a common atmospheric element that can be found on every planet in the Solar System, as well as numerous celestial objects such as natural satellites, comets, and even huge asteroids. Extrasolar water vapour discovery would also point to a similar distribution in other planetary systems. In the case of some planetary mass objects, water vapour can be used as indirect proof for the presence of alien liquid water.
