Correct Answer - Option 4 : Avogadro's law
The correct answer is Avogadro's law.
-
Equal volumes of all gases under the same conditions of temperature and pressure contain an equal number of molecules, This is Avogadro's law.
-
Avogadro's law
- It states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules."
- Dalton's Law
- It states that the overall pressure exerted by the non-reactive gas mixture is equal to the sum of the partial pressure of the individual gases.
- Boyle's law
- Acc. to it, the pressure exerted by a gas is inversely proportional to the volume occupied by it.
- Here, of a given mass it is kept at a constant temperature.
- Charles' law
- In it, the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure.
- The law states that the Kelvin temperature and the volume will be in direct proportion when the pressure exerted on a sample of a dry gas is held constant.
