Answer 1

The branch of science which deals with the quantitative relationship between heat and other forms of energies is called thermodynamics.

Some Important Terms Related to Thermodynamics

(i) System It refers to the part of universe in which observations are carried out.

(ii) Surroundings The part of universe other than the system is known as surroundings.

(ill) Boundary The wall that separates the system from the surroundings is called boundary.

(iv) Thermodynamic equilibrium A system in which the macroscopic properties do not undergo any change with time is called thermodynamic equilibrium.

(v) Thermal equilibrium If there is no flow of heat from one portion of the system to another, the system is said to be in thermal equilibrium.

(vi) Mechanical equilibrium If no mechanical work is done by one part of the system on another part of the system. it is said to be in mechanical equilibrium. Such a condition exists when pressure remains constant
