Question
5 Two metal blocks of equal mass M of the same sub-
stance, one at an initial temperature Ti and the other at
an initial temperature T2, are placed in a well-insulated
(adiabatic) box of constant volume. A device that can
produce work from a flow of heat across a tempera-
ture difference (i.., a heat engine) is connected between
the two blocks. Develop expressions for the maximum
amount of work that can be obtained from this process
and the common final temperature of the blocks when
this amount of work is obtained. You may assume that
