Question

At 0°C and a pressure of 1000 mm, a given weight of nitrogen occupies a volume of 1.0 L. At -100°C, the same weight of gas under the same pressure occupies a volume of 0.6 L. What is the value of absolute zero in degree Celsius?

Correct answer: A. Charles's Law: V₁/T₁ = V₂/T₂. 1.0/(0 + T₀) = 0.6/(-100 + T₀) → T₀ - 100 = 0.6T₀ → 0.4T₀ = 100 → T₀ = 250. Absolute zero = -250°C.
