The entropy of a sample of a certain substance increases by 0.836 ~J ~K ⁻¹ on adding reversibly 0.3344 ~J of heat at constant temperature. The temperature of the sample is:

Options

  1. A2.5 ~K
  2. B0.3 ~K
  3. C0.016 ~K
  4. D0.4 ~K

Correct answer

D. 0.4 ~K

Step-by-step solution

S= H T ; T= H S = 0.3344 0.836 =0.4 ~K
