Melting of ice.
Ice cubes in a drink absorb heat from the drink making the drink cooler. If we forget to drink it, after some time, it again attains room temperature by absorbing the atmospheric heat. All this happens as per the first and second law of thermodynamics.

How does a car engine operates?
When compression is complete, the spark plugs ignite the fuel, which then increases the temperature and pressure at a constant volume. Then the gas expands adiabatically, called the "power stroke", resulting in a sudden drop in the pressure and temperature. This part of the reaction is what gives power to the car.

How does an air conditioner works?
An air conditioning system uses principles of thermodynamics to cool a living space. In simple terms, it is a closed system that circulates a substance called a refrigerant, altering the pressure of the refrigerant at different points to promote the transfer of heat.

Real life application of second law of thermodynamics.
The first law of thermodynamics is the application of conservation of energy principle to heat and thermodynamic processes.

Real life application of first law of thermodynamics.
The thermodynamics second law states that the entropy of an isolated system can never decrease over time, and is constant if and only if all processes are reversible in nature. The entropy increase accounts for the irreversibility of natural processes, and the asymmetry which is between past and future.

Real life application of entropy.
Entropy, the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work. Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system.
