A piston/cylinder contains air at $600 \mathrm{kPa}, 290 \mathrm{~K}$ and a volume of $0.01 \mathrm{~m}^{3}$. A constant-pressure process gives $54 \mathrm{~kJ}$ of work out. Find the final volume, the temperature of the air, and the heat transfer.

Key Concepts

Ideal Gas Law

This fundamental law relates pressure, volume, and temperature for an ideal gas. It is used to determine any one property of a gas, provided the other two and the amount of gas are known, using the relation PV = nRT or its mass-based counterparts. It underpins the analysis of many thermodynamic processes, especially when dealing with air or other gases under moderate conditions.

Constant Pressure Process

In a constant pressure process, the pressure remains unchanged during the expansion or compression of a gas. This simplifies work calculations since the work done is directly proportional to the change in volume (W = P?V). This concept is key in understanding how changes in temperature and volume interrelate under the constraint of constant pressure.

First Law of Thermodynamics

The first law of thermodynamics is the principle of energy conservation for thermodynamic systems. It states that the change in internal energy of a system is equal to the heat added minus the work done by the system. This concept is crucial for determining how energy is transferred as heat or work during any process.

Work in a Piston-Cylinder System

Work in a piston-cylinder assembly is the energy transferred across the system boundary by the movement of the piston. For a constant-pressure process, the work is calculated by multiplying the pressure by the change in volume. Understanding this concept is essential for analyzing energy interactions in systems where mechanical movement results in energy transfer.
