400 J of work is performed on a gasfor reducing its volume by compression. If the change is done adiabatically, whatisthe amount of heat absorbed by it?

The work of 146 kJ is performed in order to compress one kilo mole of a gas adiabatically and in this process the temperature of the gas increases by 7^@C . The gas is (R=8.3ml^-1Jmol^-1K^-1)

When a gas is heated at constant pressure, its volume changes and hence

A Carnot engine, having an efficiency of eta= 1/10 as heat engine, is used as a refrigerator. If the work done on the system is 10 J, the amount of energy absorbed from the reservoir at lower temperature is

104 kj of work is done on certain volume of a gas. If the gas releases 125 kj of heat, calculate the change in internal energy (in kj) of the gas.

Consider two containers A and B containing identical gases at the same pressure , volume and temperature. The gas in container A is compressed to half of its original volume isothermally while the gas in container B is compressed to half of its original value adiabatically . The ratio of final pressure of gas in B to that of gas in A is

One mole of an ideal gas requires 135 J of heat to raise its temperature by 15 ^@ K when heated at constant pressure. If the same gas is heated at constant volume to raise the temperature by the same, then the heat required will be (R = 8.3J /mole ^@K)

In an adiabatic process 90 J of work is done on the gas. The change in internal energy of the gas is

An ideal gas is compressed to half its initial volume by means of several peocesses. Which of the process results in the maximum work done on the gas ?

When the temperature of 5 mol of a gas is changed from 100^@C to 120^@C keeping the volume constant, the change in internal energy of the gas is 80 J, then find the heat capacity of the gas at constant volume.
