Answer to Question #323632 in General Chemistry for micheal

Question

A gas at a temperature of 127 0C is heated in a freely expandable container until its volume doubles. What is the new temperature of the gas?  

Answer 1

T1 = 127 C = 400 K;

V₂ = 2 * V₁;

V₁/T₁ = V₂/T₂ or V₁/T₁ = 2 * V₁/T₂;

T₂ * V₁ = 2 * V₁ * T₁;

T₂ = 2 * V₁ * T₁/V₁ = 2 * T₁ = 2 * 400 = 800 K = 527 C.

Answer: 527 C.
