You can calculate pressure and temperature for a constant volume process using the combined gas law.
Initially, a minimum of 5.2 bar is needed to convert air to liquid under pressure. This pressure is for the initial process. For the final process, less than 1.7 bar is needed.
At engineering level technically both process are same except there definition both process give hyperbolic curve in P-V diagram and straight line in T-S diagram. and even in polytropic process PV^n=constant if n=1 then it is not hyperbolic process it is isothermal process even though the definition says pv=c is hyperbolic process.

At the boiling point the energy goes into breaking the intermolecular bonds, but the average kinetic energy stays constant and so does the temperature until all of the bonds are broken and the substance is in the vapor state.

When analyzing a constant pressure expansion process, key factors to consider include the initial and final pressure, volume, and temperature of the system, as well as the work done and heat transferred during the process. Additionally, understanding the ideal gas law and the concept of enthalpy can help in analyzing the behavior of the system accurately.
In an adiabatic process for an ideal gas, the integral of Cp dT/T is equal to R ln(P2/P1), where Cp is the specific heat at constant pressure, R is the gas constant, P1 is the initial pressure, and P2 is the final pressure. This relationship shows that the change in temperature with respect to the initial and final pressures is related to the specific heat capacity and gas constant.
An isobaric process is a thermodynamic process that occurs at a constant pressure. This means that the system is allowed to exchange heat with its surroundings but the pressure remains the same throughout the process. In an isobaric process, the work done is determined by the change in volume of the system.
A piston cylinder process actually includes two processes. The gas inside the piston undergoes both the constant pressure process and the contant volume process.
In Polytropic process the product of Pressure and Volume (PV) power 'n' is constant where, 'n' is polytropic index
An isobaric process is when pressure remains constant, while an isothermal process is when temperature remains constant in thermodynamics.
The process is called isothermal expansion. This occurs when a gas expands and cools down while maintaining a constant pressure.
An isothermal process in thermodynamics is when the temperature remains constant, while an isobaric process is when the pressure remains constant.
Boyle's Law, which states that pressure and volume are inversely proportional at a constant temperature, expressed as PV = constant. Mathematically, this can be written as P1V1 = P2V2, where P represents pressure and V represents volume at different points in the process.
Temperature is constant during an isothermal process. The work done (W) is equal to the heat added (Q). The change in internal energy (ΔU) is zero for an isothermal process. The pressure can vary during an isothermal process, depending on the specific conditions.
Constant pressure enthalpy is a measure of the energy content of a system at a constant pressure. During a process, changes in the system's energy content are reflected in the enthalpy changes. The relationship between constant pressure enthalpy and changes in energy content is that they are directly related - as the enthalpy changes, so does the energy content of the system.
If pressure is held constant, volume and temperature are directly proportional. That is, as long as pressure is constant, if volume goes up so does temperature, if temperature goes down so does volume. This follows the model V1/T1=V2/T2, with V1 as initial volume, T1 as initial temperature, V2 as final volume, and T2 as final temperature.
