|
Law of conservation of mass
|
|
Law of definite proportion
|
|
Law of multiple proportion
|
|
Avogadros law
|
Explanation:
Detailed explanation-1: -Which law says this ? Notes: Avogadro’s law says that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules. This empirical relation can be derived from the kinetic theory of gases under the assumption of a perfect (ideal) gas.
Detailed explanation-2: -Avogadro’s law states that equal volumes of gases at the same temperature and pressure contains equal number of molecules.
Detailed explanation-3: -The statement, “Equal volumes of different gases under similar conditions of temperature and pressure contain equal number of atoms.” is false.
