Answer to Question #116126 in General Chemistry for Chelse Bell

Question

The pressure inside a container is 770 kPa at a temperature of 57.0oC. What would the pressure be at 75oC?

Answer 1

P₁ = 770 kPa;

P₂ = unknown;

V₁ = V₂ = constant;

T₁ = 57 °C = 330.15 K;

T₂ = 75 °C = 348.15 K;

Solution:

(P₁×V₁)/(T₁) = (P₂×V₂)/(T₂);

V₁ = V₂ = constant;

P₁/T₁ = P₂/T₂;

P₂ = (P₁×T₂)/T₁;

P₂ = (770 kPa×348.15 K)/(330.15 K) = 812 kPa;

Answer: 812 kPa
