Answer
Option (c) $–0.0304$ kJ/K
Work Step by Step
Solved by EES Software. Solutions can be verified by copying-and-pasting the following lines on a blank EES screen.
$c=3.65$ "kJ/kg.K"
$m=0.12$ "kg"
$T_1=25$ "C"
$T_2=5$ "C"
$S_{\text{change}}=m*C*\ln((T2+273)/(T1+273))$
Option (c) $–0.0304$ kJ/K is correct.
