The entropy may be expressed as a function of
A. Pressure and temperature
B. Temperature and volume
C. Heat and work
D. All of these
Answer: Option D
Solution (By Examveda Team)
The entropy (S) is a thermodynamic property that quantifies the degree of disorder or randomness in a system. It can be expressed as a function of various thermodynamic parameters. Option D, All of these, is the correct choice because entropy can indeed be expressed as a function of pressure and temperature, temperature and volume, as well as heat and work.Entropy as a function of pressure and temperature (S = f(P, T)) is applicable in various processes such as isothermal processes, isobaric processes, and adiabatic processes where pressure and temperature changes occur simultaneously.
Entropy as a function of temperature and volume (S = f(T, V)) is relevant in processes like isentropic processes, where temperature and volume variations are significant.
Entropy as a function of heat and work (S = f(Q, W)) is applicable in thermodynamic cycles such as the Carnot cycle, where the heat transfer (Q) and work done (W) are crucial parameters.
Therefore, Option D correctly encompasses all these possibilities, making it the most suitable choice.

option D is correct. entropy changes is expressed in combination of any two - p,v,t in formulations , also external heat transfer is related to entropy, as dQ/T ... and work transfer associates with entropy if there is heat generation, otherwise high quality energy results in no entropy generation. So opt D is correct, as all parameters connects or results in entropy change and hence entropy can be expressed in all above parameters.
please describe it more as in question option A is showing correct.But when I checked it is showing Option B is the correct option.I think there is a mistake please correct that mistake because it will confuse which option is correct
Ans is wrong and d option is correct
Sole function of entropy is temperature.
According to Tds = du + pdv
And Tds = dh - vdp
Entropy can be a function of volume also
entropy can also expressed as vol and tem...
Entropy as a function of Temperature and volume.
I am not understanding how Entropy can be expressed as a function of "pressure and temperature"?
