Physics ISOBARIC AND ISOCHORIC PROCESS

Isobaric Process

In an isobaric process, P is fixed. Work done by the gas is

`W = P (V_2 - V_1) = mu R (T_2 - T_1)`

Since temperature changes, so does internal energy. The heat absorbed goes partly to increase internal energy and partly to do work.

The change in temperature for a given amount of heat is determined by the specific heat of the gas at constant pressure.

Isochoric Process

In an isochoric process, V is constant. No work is done on or by the gas.
`W=int_(V_1)^(V_2)PdV`

From `ΔQ = ΔU + ΔW`, the heat absorbed by the gas goes entirely to change its internal energy and its temperature.

The change in temperature for a given amount of heat is determined by the specific heat of the gas at constant volume.
