MCQ
Pressure exerted by a perfect gas is equal to
  • A
    mean K.E. per unit volume.
  • B
    half of mean K.E. per unit volume.
  • C
    one-third of mean K.E. per unit volume.
  • ✓
    two-third of mean K.E. per unit volume.
✓

Answer

Correct option: D.
two-third of mean K.E. per unit volume.
two-third of mean K.E. per unit volume.
Solution :
$P=\frac{2}{3}$ K.E. (average K.E. of the gas per unit volume).
