Answer to Question #337086 in General Chemistry for Cosmo

Question

Oxygen gas is a temperature of 40 C when it occupies a pressure of 12.30 psi. To what temperature will it have at a pressure of 6.50 psi?

Answer 1

P₁T₂ = P₂T₁

T₂ = P₂T₁ / P₁

T₁ = 40°C = 313.15 K, P₁ = 12.30 psi = 0.817 atm, P₂ = 6.50 psi = 0.408 atm

T₂ = (0.408 atm * 313.15 K) / 0.817 atm = 156.38 K
