by using the ideal gas law PV=nRT
P= pressure= 1.10 atm V= volume= ? ; n= moles=0.718 moles
R= gas constant= 0.0821 Latm/molK T= temperature = 293 K
V= nRT/P= 0.718*0.0821*293/1.10 = 17.27/1.10= 15.7 L

Consider a piston cylinder process in air (as an ideal gas with constant specific heats) which goes from state 1 at 1 atm, 300 K to state 2 at: 3 atm and 400K. (use k=1.4, Cp = 1.005 kJ/(kg K), Cv=0.718 kJ/(kg K), R= 0.287 kJ/(kg K)) (these are the same conditions as question 4). What must the heat transfer be (in kJ/kg), if the process takes place without entropy generation and it can be assumed the temperature at system...
