Statement I: The ratio of volume and absolute temperature is constant for a fixed amount of gas at constant pressure. Statement II: At constant pressure, the volume of a given mass of a gas increases

Question

Statement I: The ratio of volume and absolute temperature is constant for a fixed amount of gas at constant pressure. Statement II: At constant pressure, the volume of a given mass of a gas increases or decreases by 1/273 of its volume at 0°C, for each 1°C rise or fall in temperature, respectively.

Correct answer: A. Statement I is Charles's Law (V/T = constant). Statement II is the original definition of Charles's Law, which mathematically leads directly to V ∝ T (Statement I). Thus, Statement II is the correct explanation.
