Question

1000ml of a gas is cooled from 500 K to 250 K, what is it's final volume? A. 250 ml B. 1000 ml C. 500 ml D. 750 ml E. 2000 ml

Answer 1

Charle's Law states that volume and temperature have an inverse relationship.

V/T = k
where k is some constant

We can use this to solve our question
V₁/T₁ = k = V₂/T₂
V₁/T₁ = V₂/T₂

1000 mL = 1 L

1L/500K = V₂/250K
V₂ = 0.5 L = 500 mL

The correct answer is C. 500 mL
