We need to know the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure.
The relationship is: As air pressure in an area increases, the density of the gas particles in that area increases.
For any gaseous substance, density of gas is directly proportional to pressure of gas.
This can be explained from idial gas edquation:
PV=nRT
PV=
RT [where, w= mass of substance, M=molar mass of substance]
PM=
RT
PM=dRT [where, d=density of thesubstance]
So, for a particular gaseous substance (whose molar mass is known), at particular temperature, pressure is directly related to density of gaseous substance.
Therefore, as air pressure in an area increases, the density of the gas particles in that area increases.

Complete Question
To make use of an ionic hydrate for storing solar energy, you place 422.0 kg of sodium sulfate decahydrate on your house roof. Assuming complete reaction and 100% efficiency of heat transfer, how much heat (in kJ) is released to your house at night? Note that sodium sulfate decahydrate will transfer 354 kJ/mol.
Answer:
The amount of energy released is 
Explanation:
Number of moles is mathematically represented as
substituting 
for mass of sodium sulfate decahydrate(
), 
(This value is a constant )for the molar mass of sodium sulfate decahydrate
From the question we are told that
1 mole of sodium sulfate decahydrate generates 
of energy
So 1309.7 mole would generate x
Now stating the relation mathematically
1 mol → 354KJ
1309.7 mol → x
=>
