JEE PYQ: Thermodynamics Question 18
Question 18 - 2020 (09 Jan Shift 2)
The true statement amongst the following is:
(1) Both $\Delta S$ and $S$ are functions of temperature.
(2) Both $S$ and $\Delta S$ are not functions of temperature.
(3) $S$ is not a function of temperature but $\Delta S$ is a function of temperature.
(4) $S$ is a function of temperature but $\Delta S$ is not a function of temperature.
Show Answer
Answer: (1)
Solution
A system at higher temperature has greater entropy (randomness). $\Delta S$ is related with $q$ and $T$ as: $\Delta S = \int \dfrac{dq}{T}$.
