Question

state the first and second law of thermodynamics

Answer 1

First Law of Thermodynamics: The amount of heat given to a system is used up in two ways, first to increase the internal energy and second to do the external work.

Second Law of Thermodynamics: The second law of thermodynamics is the outcome of human experience under which heat energy can be converted into mechanical energy.

Answer 2

Answer:

The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic processes, distinguishing two kinds of transfer of energy, as heat and as thermodynamic work, and relating them to a function of a body's state, called Internal energy.

The second law states that if the physical process is irreversible, the combined entropy of the system and the environment must increase.
