Starting from equilibrium at point 0, what point on the pv diagram will describe the ideal gas after the following process? lock the piston head in place, and hold the container above a very hot flame.

Isobaric Process.

The isobaric process is a thermodynamic process where the pressure is constant: ΔP = 0.

Isobaric stated that if a situation in an ideal gas cylinder has a fixed volume then if the temperature is changed the cylinder pressure will change linearly. In the isobaric process, the system pressure is kept constant.

According to the first law of thermodynamics, where W is the work done on the system, U is the energy in and Q is heated with Δ indicating changes during the process, while d is the differential symbol.

If a gas carries out a thermodynamic process by keeping the pressure constant, the gas is said to carry out an isobaric process. Because gas is under constant pressure, it does business (W = p∆V). The heat here can be expressed as gas heat at a constant pressure Qp. Thus, the work done by gas (W) can be expressed as the difference in energy (heat) that is absorbed by the gas at constant pressure (Qp) with the energy (heat) absorbed by the gas at a constant volume (QV).

In an isobaric process, there is usually a change in internal energy, work is carried out by the system, and heat is transferred so that no amount in the first law of thermodynamics easily reduces to zero.
