Question

Let Ta and Tb be the final temperatures of the samples A and B, respectively, in the previous question.
(a) Ta < Tb
(b) Ta = Tb
(c) Ta > Tb
(d) The relation between Ta and Tb cannot be deduced.

Answer 1

The correct answer is (a), which is Ta < Tb.

Explanation:

• By means of isothermal process, as an expansion is undergone by the sample

• A, the initial and final temperatures will always remain the same, that is, Tb. On the contrary, at the initial state as sample B, sample A is the same, in such a way that A’s initial temperature ​Tb and it is increasing via an adiabatic process in which no heat is provided.

• Consequently, at the cost of its internal energy, sample A will expand and less than the initial temperature, its final temperature will be less. This shows that Ta < Tb.
