The mass of water vapour present in 1 m³ of dry air

The ratio of the actual mass of water vapour in a unit mass of dry air to the mass of water vapour in the same mass of dry air when it is saturated at the same temperature and pressure

The mass of water vapour present in 1 kg of dry air

The ratio of actual mass of water vapour in a given volume of moist air to the mass of water vapour in the same volume of saturated air at the same temperature and pressure

The value of C.O.P. is always greater than one

None of the listed here

In a vapour compression system, the condition of refrigerant before entering the compressor is dry saturated vapour

The space between the saturated liquid line and saturated vapour line, in a pressure enthalpy chart, is wet vapour region
