Thermodynamics question

2022 · Q106

NEETChemistryThermodynamicsMCQ+4 / −1

One mole of an ideal gas at 300 K is expanded isothermally from 1 L to 10 L volume. Δ\DeltaΔU for this process is :

(Use R = 8.314 J k−-−1 mol−-−1)

  1. A
    0 J
  2. B
    1260 J
  3. C
    2520 J
  4. D
    5040 J

Correct answer: A

$\Delta$U = nCv$\Delta$T

For isothermal condition; $\Delta$T = 0

$\therefore$ $\Delta$U = 0
