Question

(i) How does the internal energy of an ideal gas change as it follows path i → f as shown? (a) E_int increases. (b) E_int decreases. (c) E_int stays the same. (d) There is not enough information to determine how E_int changes. (ii) From the same choices, how does the internal energy of an ideal gas change as it follows path f → f ' along the isotherm labeled T + ΔT as shown?

For the constant-volume
path, all the energy input
goes into increasing the
internal energy of the gas
because no work is done.

Along the constant-pressure
path, part of the energy
transferred in by heat is
transferred out by work.
Figure 20.4 Energy is trans-
ferred by heat to an ideal gas in
two ways.
