(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The volume of a gas is decreased by a constant external pressure of 0.25 atm, changing from 2.0 liters to 0.50 liters. During this compression, 75 J of energy flows out of the gas. Find the work done by the gas and its change in internal energy.

2. Relevant equations

First Law of Thermodynamics= ΔE=Q - W

3. The attempt at a solution

Is 75 J of energy the final energy

I'm not too sure on how to find the Q or W

I'm not too sure on how to complete this problem

Could someone me help on how to start the problem
