Question

An ideal gas undergoes a process from state 1 (T1=300 KT_1 = 300\text{ K}, p1=100 kPap_1 = 100\text{ kPa}) to state 2 (T2=600 KT_2 = 600\text{ K}, p2=500 kPap_2 = 500\text{ kPa}). The specific heats of the ideal gas are : cp=1 kJ/kg-Kc_p = 1\text{ kJ/kg-K} and cv=0.7 kJ/kg-Kc_v = 0.7\text{ kJ/kg-K}. The change in specific entropy of the ideal gas from state 1 to state 2 (in kJ/kg-K) is ___________(correct to two decimal places).
