One Mole Of An Ideal Mono-atomic Gas Is Heated At A Constant Pressure Of One Atmosphere From 0oC To 100oC. The Heat Taken From The Source Is:

A motor-car tyre has a pressure of 2 atmosphere at 27^oC. It suddenly bursts. If (C_p/C_v) = 1.4 for air, find the resulting temperature:

Find the  amount of work done to increase the  temperature of one mole of ideal gas by 30^oC, if it is expanding under the condition  (R = 8.31 J/mol-K):

For an adiabatic expansion of a perfect gas, the value of  is equal to:

In an adiabatic expansion of a gas, the product of pressure and volume:

One of the most efficient engines ever developed operates between 2100 K and 700 K. Its actual efficiency is 40%. What percentage of its maximum possible efficiency is this?

In an adiabatic change, the pressure P and temperature T  of a diatomic gas are related by the relation   where C equals:

By opening the door of a refrigerator inside a closed room:

One mole of an ideal mono-atomic gas is heated at a constant pressure of one atmosphere from 0^oC to 100^oC. Then the change in the internal energy is:

One mole of an ideal mono-atomic gas is heated at a constant pressure of one atmosphere from 0^oC to 100^oC. The work done by the gas is:

Three moles of an ideal mono-atomic gas perform a cycle as shown in figure. The gas temperatures in different states are  The work done by the gas during the cycle will be:
