A real gas is subjective to an adiabatic process form `(2"bar",40L,300K)` to `(4"bar",30L,300K)` against a constant pressure of 4 bar. The enthalpy change for the process is `(1"bar"-litre=100J):`

1 mole of real gas is subjected to a process from (2 "bar", 40 lit., 300K) to ( 4 bar , 30 lit., 400K) . If Change in interal energy is 20 kJ then calculate enthalpy charge for the process.

One mole of a real gas is subjective to a process form (2"bar",30lit,300k) to (2"bar",50lit,400k) Given C_(v)=40J//mol//K,C_(P)=50J//mol//K Calculate triangleU .

A certain gas is expanded from (1L, 10atm) to (4L, 5atm) against a constant external pressure of 1 atm. If the initial temperature of gas is 300K and heat capacity for the process is 50J ""^(@)C^(-1) (use 1L atm = 100J), then

A certain gas is expanded from (1L, 10atm) to (4L, 5atm) against a constant external pressure of 1 atm. If the initial temperature of gas is 300K and heat capacity for the process is 50J ""^(@)C^(-1) (use 1L atm = 100J), then

A certain mass of an ideal gas absorbes 80 kJ heat and gas is expended from 2 L to 10 L at constant pressure of 25 bar. What is DeltaU for gas in the process ? ( 1 bar-L= 100 J)

A certain gas in expanded from (1L, 10 atm) to (4L, 5 atm) against a constant external pressure of 1atm . If the initial temperature of gas is 300K and heat capacity for the process is 50J^(@)C^(-1) , the enthalpy change during the process is: (use: 1L-atm = 100J)
