In which of the following cases entropy increases?

Solution
The correct options are
A Solid changing to liquid
B Crystal dissolve
C Expansion of a gas
In thermodynamics, entropy (usual symbol S) is a measure of the number of specific ways in which a thermodynamic system may be arranged, commonly understood as a measure of disorderliness.
Solid changing to liquid, expansion of a gas, crystal dissolve all these processes involves the disorderliness of particles, in all these processes entropy increases.
But in the case of polymerisation small molecules can join together to make very long molecules called polymers. This process is called polymerisation. Many polymers are made from chemicals that are obtained from crude oil. For example, molecules of ethene join together to make poly (ethene), commonly known as polythene.) Entropy decreases due to polymeriastion.
Hence options A, B & C are correct.
