The law that states the volume of a given mass of gas is directly proportional to its temperature at constant pressure is B) Charles's Law.
Charles's Law: It describes the relationship between the volume and temperature of a gas at constant pressure, meaning as the temperature increases, the volume also increases proportionally. V∝T at constant pressure.
Boyle's Law: This law states that the volume of a gas is inversely proportional to its pressure at constant temperature. PV=constant at constant temperature.
Avogadro's Law: This law states that the volume of a gas is directly proportional to the number of moles of gas particles at constant temperature and pressure. Avogadro's number is equal to 6.022 x 10^23. It represents the number of atoms, molecules, ions, or other particles present in one mole of a substance.
Gay-Lussac's Law states that for a given mass of gas at a constant volume, the pressure exerted by the gas is directly proportional to its absolute temperature.
This means that as the temperature of the gas increases, the pressure it exerts also increases, and vice versa, when the volume remains constant.
The mathematical representation of this relationship is P ∝ T at constant volume.
