This question has two parts.
A. A small, closed chamber of gas is heated. When the gas in the
chamber expands, it does 5 J of work on a piston. The gas has
an initial energy of 8 Jand a final energy of 30 J. Considering
the equation for the first law of thermodynamics (AU = Q + W).
does the work done in this scenario have a positive or negative
value? Explain
B. How much heat is added to the gas in the chamber?
