Pressure Volume Work Calculator
To find work from pressure and volume, multiply the pressure by the change in volume and add a negative sign.
Pressure Volume Work Calculator
This calculator helps you find the work done when a gas expands or compresses. When a gas changes volume under pressure, it does work. This concept is important in thermodynamics, chemistry, and physics.
This tool is useful for students, engineers, and scientists who study gases, energy transfer, and mechanical systems. Instead of solving long equations, just enter the values, and the calculator will give the answer instantly.
Formula
The formula for pressure-volume work is:
| Symbol | Meaning |
|---|---|
| W | Work Done (Joules) |
| p | Pressure (Pa or atm) |
| dV | Change in Volume (m³ or L) |
What is Pressure Volume Work?
Pressure-volume work happens when a gas expands or compresses under pressure. The negative sign in the formula shows that when a gas expands, it does work on its surroundings, and when it compresses, work is done on the gas.
For example, in a car engine, gases expand inside cylinders, pushing pistons to generate motion and energy. This principle is used in engines, refrigeration, and many industrial systems.
Understanding pressure-volume work helps in studying gas laws, energy efficiency, and thermodynamics.
Final Words
To sum up, gases do work when they expand or compress. This calculator makes it quick and easy to find work done in physics, chemistry, and engineering.
FAQs
1. How to calculate pressure-volume work?
Use the formula: W = – p × dV, where p is pressure and dV is the change in volume.
2. How do you calculate volume from pressure?
Use gas laws to find volume based on pressure and temperature.
3. What is the expression for pressure-volume work?
It is work = – pressure × change in volume.
