What is Heat
Heat is a form of energy. It is the interaction between the 
system and the surrounding which occurs by virtue of their 
temperature difference when they communicate
The SI unit of heat is Joule. But another unit of heat i.e. 
calorie is also widely used.

Specific Heat
Specific heat of a substance is the amount of heat required to 
raise the temperature of unit mass of a substance by 1ºC.

Specific heat of a substance is the amount of heat required to 
raise the temperature of unit mass of a substance by 1ºC.
Zeroth law of thermodynamics (continued)
According to this law, "If system A and B are each in thermal 
equilibrium with a third system C, then A and B are in 
thermal equilibrium with each other."

Zeroth law of thermodynamics
When two systems are in thermal equilibrium than only 
temperature is the property of the system which is equal to 
that of another system. It is not necessary that pressure and 
volume of two different systems would also remain same.
