Extensive properties The properties of the system, whose value for the entire system is equal to the sum of their values for the individual parts of the system, are called extensive properties.
For example, total volume, total mass and total energy of a system are extensive properties.
Intensive properties The properties of the system, whose value for the entire system is not equal to the sum of their values for the individual parts of the system, are called intensive properties.
For example, temperature, pressure and density of a system are intensive properties.

Answer is:
Zeroth law of thermodynamics
Explanation:
Zeroth law of thermodynamics : Zeroth law of thermodynamics states that, when two bodies are in thermal equilibrium with a third body. They are also in thermal equilibrium with each other.
Answer is:
Total energy of a system remains constant.
Explanation:
First law of thermodynamics: First law of thermodynamics states that, Heat and mechanical work are mutually convertible. According to this law, a definite amount of mechanical work is needed to produce a definite amount of heat and vice versa.
First law of thermodynamics also states that energy can neither be created nor destroyed, through it can be transformed from one form to another. According to this law, the energy due to heat supplied must be balanced by external workdone plus the gain in internal energy due to rise in temperature.
