Question

why does the pressure of atmosphere decreases when the temperature increases????

Answer 1

Answer:

As the temperature increases, there is no pressure pushing on the molecules (like on the surface of the Earth) so they can spread out as much as they want. Only gravity pulls on them. They spread out so much that there is actually less pressure than on a place the same temperature lower in the atmosphere

Answer 2

Answer:

$\bold\pink{DUE\:TO\:CHANGE\:IN\:AIR'S\:DENSITY-}$

Explanation:

This change in pressure is caused by changes in air density , and air density is related to temperature. Warm air is less dense than cooler air because the gas molecules in warm air have a greater velocity and are farther apart than in cooler air.
