A closed system containing gas is fitted with a movable piston. The introduction of 430 J of thermal energy caused the system to expand, doing 238 J of work against a constant pressure of 101 kPa. What is the resulting change in the internal energy, ΔE, of the system? A 350.0 gram sample of copper is initially at 25.0 °C. If the sample absorbs 12.50 kJ of heat from its surroundings, what is final temperature? specific heat (Cu) = 0.386 J/g °C.
