Question

Use the ideal gas law formula to show that the thermodynamics unit of pressure is J/B ( Joules / Bar)

Thanks

Answer 1

The absolute pressure (P) is the force acting on unit area. In the SI system, the unit for pressure is Pa, Pascal.Kilopascals is equivalent to newtons per meter squared. Joules is equivalent to newton-meters. To get from kPa to J you must multiply by a volume, expressed in cubic meters
