MCQ
A degenerate gas is:
  • A
    $He$
  • B
    $O_2$
  • ✓
    $\text{He(ll)}$
  • D
    $He_2$
✓

Answer

Correct option: C.
$\text{He(ll)}$
$\text{He(II)}$ is a degenerate gas. A degenerate gas is one where quantum mechanical effects on the electrons dominate the behavior.A degenerate electron gas can permanently withstand the self$-$gravitation. its energy cannot be radiated away.
