An ideal gas [Cp = 1.0 kJ/kg-K, R (Gas constant) = 0.3 kJ/kg-K] is compressed from an initial state of 100 kPa and 300 K to 600 kPa and 330 K. What will be the change in entropy of the gas during the process?
[Given : e1.8 = 6, e0.095 = 1.1]
1
-0.445 kJ/kg-K
2
-4.45 kJ/kg-k
3
-44.5 kJ/kg-k
4
+4.45 kJ/kg-k
