WebCALC The temperature of 0.150 mol of an ideal gas is held constant at 77.0°C while its volume is reduced to 25.0% of its initial volume. The initial pressure of the gas is 1.25 atm. (c) Does the gas exchange heat with its surroundings? If so, how much? Does the gas absorb or liberate heat?

Webonly if the specific heats are constant. We can relate the specific heats of an ideal gas to its gas constant as follows. We write the first law in terms of internal energy, and assume a quasi-static process so that we can also write it in terms of enthalpy, as in Section 2.3.4, WebNov 5, 2024 · Specific Heat for an Ideal Gas at Constant Pressure and Volume. The heat capacity at constant volume of nR = 1 J·K −1 of any gas, including an ideal gas is: \[\mathrm{(\dfrac{∂U}{∂T})_V=c_v}\] This represents the dimensionless heat capacity at constant volume; it is generally a function of temperature due to intermolecular forces.

The heat capacity of an object, denoted by , is the limit where is the amount of heat that must be added to the object (of mass M) in order to raise its temperature by .
