Hers, dS= dQ/T.

Question is what does entropy represents (Not proportional or depends). Like the differential equation, I think it shows degradation of available energy.

Please anyone explain.

Ram said:   9 years ago
It is dS = dQ/T. So A is the correct answer.

Abdul Rahman said:   9 years ago
I too think it is option B.

Sahil said:   9 years ago
Answer is b because entropy is a function of temperature.

Explanation : As entropy means degree of randomness, so increase in entropy means that there is an increase in randomness. So, useful energy is degraded or lost.

Entropy is the property which increase with addition of heat and decrease with removal of heat. So I think option B is the right.

How it is?
