Statement-1: When an ideal gas is taken from a given thermodynamic state to another given thermodynamic state by any polytrophic process, the change in the interval energy of the system will be the same in all processes.
Statement-2: Internal energy of the gas depends only upon its absolute temperature.
Statement-2: Internal energy of the gas depends only upon its absolute temperature.
View answer and explanation
Correct option: A
Statement-1 is true, Statement-2 is true, Statement-2 is the correct explanation for Statement-1
Option A is correct because the change in internal energy of an ideal gas depends only on its initial and final temperatures, and the internal energy itself is a function of absolute temperature only. Therefore, the change in internal energy will be the same regardless of the path taken.
