One mole of an ideal monoatomic gas is processed in process ABCD then answer the following question (Given : R = 2 cal./mol-K)

A monoatomic ideal gas is taken through cyclic process ABCA shown in density – temperature curve as:Consider the following statements and choose the correct option(s). Take number of moles of the gas to be 1.Heat absorbed in process A→B is RT0Heat absorbed in process A→B is 0.5 RT0Efficiency of the process is ln 4−1ln 4+0.5Efficiency of the process is ln 8−1ln 8+0.5

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 :

Figure shows variation of internal energy (U) with the pressure (P) of 2.0 moles gas in cyclic process abcda.  The temperature of gas at c and d are 300 K and 500 K.  Heat absorbed in the process  is 400 R ln X.  Find the value of X.

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
