問題詳情

37. One mole of an ideal gas undergoes an isothermal reversible expansion at 300 K. During the
process, the system absorbs 750 J of heat from the surroundings. When this gas is
compressed to the original state in one step isothermally, twice as much work is done on the
system as was performed on the surroundings in the expansion. Which of the following
statements are TRUE?

(A)

for the one-step isothermal compression is 2.5 J/K.

(B)

for the one-step isothermal compression is 5.0 J/K.

(C)

for the reversible isothermal expansion is zero.

(D)

for the overall process (expansion and compression) is zero.

(E)

for the overall process (expansion and compression) is -2.5 J/K.
