400
Amount of heat required to convert a unit mass of a liquid into vapor without a change in temperature.
What is Latent Heat of Vaporization?
400
At equal temperatures and pressure, equal volumes of gas contain the same number of molecules regardless of their chemical nature and physical properties.
