Sheldon Schwartz · Answer 1

Answer is: the temperature of the air reduces by half.

The Pressure Temperature Law - the pressure of a given amount of gas held at constant volume is directly proportional to the temperature:

P ₁/T₁ = P₂/T₂.

P₁ = 2P₂.

2P₂/T₁ = P₂/T₂.

T₂ = T₁P₂/2P₂.

T₂ = T₁/2.

As the pressure goes down, the temperature also goes down.
