Two moles of a certain gas at a temperature T_0=300K were cooled isochorically so that the pressure of the gas got reduced 2 times. Then as a result of isobaric process, the gas is allowed to expand till its temperature got back to the initial value. Find the total amount of heat absorbed by gas in this process.

Two moles of a certain ideal gas at 300K were cooled at constant volume so that the pressure was reduced to half t he initial value. Then, as a result of heating at constant pressure, the gas expanded till its temperature got back ot the initial value. Find the total amount of heat absorbed by the gas in the process.

Two moles of a certain ideal gas at 300K is cooled at constant volume so that the pressure is reduced to half the original value. Now the gas is heated at constant pressure so that its temperature becomes equal to the initial temperature. Find the total amount of heat absorbed by the gas in the process.

One mole of an ideal gas at temperature T was cooled isochorically till the gas pressure fell from P to (P)/(n) . Then, by an isobaric process, the gas was restored to the initial temperature. The net amount of heat absorbed by the gas in the process is

Six grams of hydrogen gas at a temperature of 273 K isothoermally expanded to five times its initial volume and then isochorically heated so that the pressure in the final state becomes equal to that in the initial state. Find the total amount of heat absorbed by the gas during the entire process.

Two moles of an ideal gas are cooled isochorically and then expanded isobarically to lower the gas temperature back to the initial value. Find the entropy increment of the gas if in this process the gas pressure changed n = 3.3 times.

In a cyclic process initially a gas is at 10^5 Pa pressure and its volume is 2 m^3 . First it undergoes an isobaric expansion to increase its volume to 2.5 m^3 . The in an isochoric process its pressure is doubled. Now the gas is brought back to its initial state by changing the pressure of gas linearly with its volume. Find the total amount of heat supplied to the gas in the process.

Three moles of an ideal gas being initially at a temperature T_i=273K were isothermally expanded 5 times its initial volume and then isochorically heated so that the pressure in the final state becomes equal to that in the initial state. The total heat supplied in the process is 80kJ. Find gamma(=(C_p)/(C_V)) of the gas.
