Question

If a running system has a total change in the heat of 315 joules, and it is running at a temperature of 350 K, what is the entropy?

A.1.54 joules/kelvin
B.0.847 joules/kelvin
C.1.22 joules/kelvin
D.0.900 joules/kelvin
E.0.762 joules/kelvin

Answer 1

change in entropy = change in heat/temperature

Answer 2

\[\Delta S=\frac{ \Delta Q }{ T }\]where ∆S is the change in entropy (J/K); ∆Q is the change in heat (J); and T is the temperature (K).
