  Specific heat capacity
The specific heat capacity (abbreviated s, also called specific heat) of a substance is defined as the amount of heat energy required to raise the temperature of one gram of the substance by one Kelvin (equivalently one degree Celsius).
Specific heat capacity is therefore heat capacity per unit mass.

The specific heat capacity (symbol c or s, also called specific heat) of a substance is defined as heat capacity per unit mass.
The equivalent definition using cgs units is the amount of energy (measured in ergs) required to raise the temperature of one gram of the substance by one degree Celsius (erg/(g·°C)).
Temperature: Measuring the heat capacity of water produces different results if the starting point is 20 °C rather than 60 °C. Therefore the temperature at which the measurement was conducted must be specified for the value to be useful.

 Water vapor - Wikipedia, the free encyclopedia
The measurements are expressed as specific humidity or percent relative humidity.
The temperature of the atmosphere and the water surface determines the equilibrium vapor pressure, 100% relative humidity occurs when the partial pressure of water vapor is equal to the equilibrium vapor pressure.
Measurements of vapor concentration are expressed as specific humidity or percent relative humidity.
