Easy MCQ +4 / -1 PYQ · JEE Mains 2020

For one mole of an ideal gas, which of these statements must be true?
(a) U and H each depends only on temperature
(b) Compressibility factor z is not equal to 1
(c) CP, m – CV, m = R
(d) dU = CVdT for any process

  1. A (a), (c) and (d) Correct answer
  2. B (a) and (c)
  3. C (c) and (d)
  4. D (b), (c) and (d)

Solution

For 1 mole of ideal gas : <br><br>1. Both internal energy (U) and Enthalpy (H) depends on temperature <br><br>2. Compressibility factor Z = 1 <br><br>3. C<sub>P, m</sub> – C<sub>V, m</sub> = R <br><br>4. dU = C<sub>V</sub>dT for all process
