First, assume ideal gas behavior for simplicity. To simplify even further, let's use the formula for special cases. In cases where the system is at constant volume, we will use the Gay-Lussac's Law written below:

P₁/T₁ = P₂/T₂

Note that T should be absolute. Let's solve for T₂.

1 atm/25+273 K = 0.5 atm/T₂+273 K

Solving for T₂,

T₂ = 124°C
