One mole of a real gas is subjected to a process from (2 bar, 30 lit, 300 K) to (2 bar, 50 lit, 400 K)Given :  CV = 40 J/mol/K, Cp = 50 J/mol/KCalculate ΔU

1 mole of an ideal gas A(CV, m = 3R) and 2 mole of an ideal gas B are  taken in a container and expanded reversible and adiabatically from 1 litre to 4 litre starting from initial temperature of 320 K. ΔE or ΔU for the process is :

Two thermodynamical process are shown in the figure. The molar heat capacity for process A and B are CA and CB. The molar heat capacity at constant pressure and constant volume are represented by CP and CV, respectively. Choose the correct statement.

In an isothermal process, a mass of gas has its volume reduced from 50 cm3 to 32 cm3. If the initial pressure of the gas is 80 kPa, determine its final pressure.a.125 Pab.125kPac.1.25kPad.12.5kPaClear my choice
