Solution

The correct option is A Cooled
Given,
Inversion temperature of $H e$ is very low
Now,
He expands on heating
$P V \propto R T$
As the temperature increases, $H e$ gas also expands.

Q. When helium gas is allowed to expand into vacuum, heating effect is observed. The reason for this is:

(Assume

A bubble of 5.00 mol of helium is submerged at a certain depth in liquid water when the water (and thus the helium) undergoes a temperature increase $Δ T$ of ${20.0}^{\circ} C$ ; at constant pressure. As a result, the bubble expands. The helium is monoatomic and ideal. How much work W is done by the helium as it expands against the pressure of the surrounding water during the temperature increase? Use the first law of thermodynamics.
