Work is high grade energy so entropy can not be expresse as function of work,

Entropy express as function of T&P, T&V, and heat.

So correct answer is A&B.

I also agree with you @Vivek.

Priyanshu said:   8 years ago
Entropy is a function of all available options.

So, D is the correct answer.

Priyanka said:   8 years ago
I think entropy is a function of heat and temperature.

Tds = U+pdV.
Q = T * dS.

UnAvailable energy = f(W) = f(S) where f means function.

It can be expressed in both volume and pressure as well as temperature.

I think D is the correct answer.

Ram said:   9 years ago
Yes, entropy is a function of t,p,v.

According to me, answer A and B both are correct. Answer C is not because entropy change is associate with flow of heat only not with flow of work.

Hussain said:   9 years ago
I Bilieve that a and b answer is correct.

Because from two property rule, any property can be expressed as the function of any other two property.

Heat and work are path function and not property of the system.
