Question

Define Entropy ? why is it a state function? Explain the effect of increased
temperature on the entropy of substance.​

Answer 1

Answer:

Entropy is a degree of randomness of system.

entropy is state function because it is a function for calculation of randomness of system and for cyclic process, change in entropy = 0.

if temperature increase than entropy also increase.because on increasing temperature randomness increases so entropy also increases

Answer 2

Hi friend here is your answer

_________________________________________

State functions are the properties which depend only on the initial or the final state of the system and not on the path followed by the system

Entropy is the measure of the disorder of the system

As the temperature increases the Entropy increase because as temperature increase the randomnees of molecules increase
