Thermodynamic is the branch of chemistry that mainly deals with the heat transfer between system and surroundings. Here system is the substance for which the heat content is studied and remaining part of universe is consider as the surroundings.
The specific heat can be defined as the amount of heat per unit mass that is needed to raise the temperature of given substance by one degree Celsius.
The specific heat of water is 4.186 joule/gram °C. This can be used to calculate the heat required to raise the temperature for given substance.
The relation between specific heat, heat content and mass of substance can be written as:
Here:
q = heat content of substance
m= mass of substance in grams
C = specific heat of substance in J/g◦C
∆T = Increase in temperature
