A gas piston is a system that is used in the generators to produce energy. With the change in the volume of the piston at the constant pressure, the energy in joules is, 266.49 J.

<h3>What is energy?</h3>

The energy of the system is given by the negative product of the pressure and the change in the volume.

Given,

Pressure = 2.12 atm

Initial volume = 0.260 L

Final volume = 1.50 L

Energy = -PΔV

= - (2.12) (1.24)

= - 2.63 L. atm

Converting the units:

1 L atm = 101.325 J

-2.63 L atm = 266.49 J

Therefore, 266.49 J is the energy.
