What is the principle of entropy increase?

Answer and Explanation:

The increase in entropy principle is defined as the process in which the total change in entropy of system with its adiabatic surroundings is always positive or equal to zero. The increase in entropy mostly takes place when a solid becomes liquid because randomness is increases when solid becomes liquid so entropy is also increases.

example of increase of entropy is when solid burns and become ash, ice melting
