An 80.0-gram sample of a gas was heated from 25 °C to 225 °C. During this process, 346 J of work was done by the system and its internal energy increased by 6365 J. What is the specific heat of the gas?

Answer 1

dE = q + w
w = -346J from the problem.
dE increased by 6365 J.
Solve for q
Then q = mass x specific heat x (Tfinal-Tinitial)
Substitute and solve for sp. h.
