A gas is confined to a cylinder fitted with a piston and anelectrical heater, as shown here: Suppose that current is supplied to the heater so that 100 J ofenergy is added. Consider two different situations. In case (1)the piston is allowed to move as the energy is added. In case (2) the piston is fixed so that it cannot move. (a) In whichcase does the gas have the higher temperature after additionof the electrical energy? (b) Identify the sign (positive, negative,or zero) of q and w in each case? (c) In which case is ΔEfor the system (the gas in the cylinder) larger?

Question
A gas is confined to a cylinder fitted with a piston and an
electrical heater, as shown here:
Suppose that current is supplied to the heater so that 100 J of
energy is added. Consider two different situations. In case (1)
the piston is allowed to move as the energy is added. In case
(2) the piston is fixed so that it cannot move. (a) In which
case does the gas have the higher temperature after addition
of the electrical energy? (b) Identify the sign (positive, negative,
or zero) of q and w in each case? (c) In which case is ΔE
for the system (the gas in the cylinder) larger?
