Concept:Charles' law describes how the volume of a gas changes with temperature when pressure is held constant.
Explanation:For a fixed mass of gas at constant pressure, the volume is directly proportional to its absolute temperature.
This means that as the Kelvin temperature increases, the volume also increases in the same proportion.
Boyle's law, however, relates pressure and volume at constant temperature, not volume and temperature.
Dalton's law concerns the total pressure of a gas mixture based on partial pressures.
Graham's law describes the rates of diffusion or effusion of gases.
Among the given options, only Charles' law directly connects volume and temperature.
Answer:B. Charles' law
