The true statement amongst the following is:

Options

  1. ABoth Δ S and S are functions of temperature.
  2. BBoth S and Δ S are not functions of temperature
  3. CS is not a function of temperature but Δ S is a function of temperature
  4. DS is a function of temperature but Δ S is not a function of temperature

Correct answer

A. Both Δ S and S are functions of temperature.

Step-by-step solution

The change in entropy and entropy at the absolute scale of the temperature are the function of the temperature. The entropy change is defined as the heat change at the constant temeprature. ΔS = ∫ dq T S T = ∫ 0 T ncdT T
