Detailed explanation-1: -The statement, “Equal volumes of different gases under similar conditions of temperature and pressure contain equal number of atoms.” is false.
Detailed explanation-2: -Avogadro’s law states that equal volumes of gases at the same temperature and pressure contains equal number of molecules. Q.
Detailed explanation-3: -A plot of the effect of temperature on the volume of a gas at constant pressure shows that the volume of a gas is directly proportional to the number of moles of that gas. This is stated as Avogadro’s law.
Detailed explanation-4: -The French chemist Joseph Gay-Lussac (1778-1850) discovered the relationship between the pressure of a gas and its absolute temperature. Gay-Lussac’s Law states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant.
Detailed explanation-5: -Boyle’s Law-states that the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant.
