Question

Explain the factors affecting Entropy

Answer 1

Factors affecting the entropy of a system :

1)With increase in temperature entropy increases because energy increases with in the system due to which randomness increases.

2)With increase in volume entropy of substance increases as it could be seen in gases the randomness increases because they have larger volume than solid and liquids .Thus the atoms have large space to bounce around.Thus on expansion entropy increases.

similarly when solid becomes liquid randomness increases and thus the entropy of a system.

3) The reaction in which the no. of molecules on product side is more than that on the reactant side ,entropy increases.
