Answer:
T₂ = 72ºC
Explanation:
In this exercise let us reduce the pressure to the SI system
P = 11 ata (1 10⁵ Pa / 1 atm) = 11 10⁵ P
y = 19380 mmHg
pressure is
P = ρ g h
P = 13.6 10³ 9.8 19380 10⁻³
P = 2.5 10⁶ Pa
Now we can use the ideal gas equation to
PV = nR T
PV / T = n R
Let's use the subscript 1 for the starting point and the subscript 2 for the point where the valve opens at a constant volume
P₁ V / T₁ = P₂ V / T₂
T₂ = P₂ T₁/ P₁
let's calculate
T₂ = (2.5 10⁶/11 10⁵ 32
T₂ = 72ºC
