QPages 76-77: Q11: HC Verma: Concepts of Physics - Volume 2 Specific Heat Capacities of Gases Pages 76-77: Q11 Solution: Let and be the final temperatures of the samples A and B,…

Let TaT_a and TbT_b be the final temperatures of the samples A and B, respectively, in the previous question.

Multiple Choice Options

  • A Ta<TbT_a < T_b
  • B Ta=TbT_a = T_b
  • C Ta>TbT_a > T_b
  • D The relation between TaT_a and TbT_b cannot be deduced.

Step-by-Step Verified Solution

**Answer:** (a) T_a < T_b. **Step-by-Step Explanation:** Adiabatic expansion cools the gas, while isothermal expansion keeps temperature constant. So T_a < T_b.
