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

\[ \text{entropy change} = \frac{ \text{change in heat}}{temperature} \Rightarrow \frac{ \text{315 joules}}{350 kelvin} \]

\[ \text{entropy change} = 0.90 \ \frac{joules}{kelvin}
\]

which option would that be?*
