JEE Main 4 April 2026, Shift 1, Chemistry Q54

Question 54 of 75 in this shift, Chemistry question 4 of 25, Section A.

Given below are two statements: Statement I: For an ideal gas, heat capacity at constant volume is always greater than the heat capacity at constant pressure. Statement II: In a constant volume process, no work is produced and all the heat withdrawn goes into the chaotic motion and is reflected by a temperature increase of the ideal gas. In the light of the above statements, choose the correct answer from the options given below
  1. (1)Both Statement I and Statement II are true
  2. (2)Both Statement I and Statement II are false
  3. (3)Statement I is true but Statement II is false
  4. (4)Statement I is false but Statement II is trueOfficial answer
