According to Charles’s law, at constant pressure the volume of a gas changes per degree Celsius by what fraction of its volume at 0 °C?
Correct answer B. 1/273
Explanation
Charles found that a gas expands or contracts by 1/273 of its 0 °C volume for every 1 °C change. This leads to Vₜ = V₀(1 + t/273).
