Air in a thundercloud expands as it rises. If its initial temperature is 300 K and no energy is lost by thermal con- duction on expansion, what is its temperature when the ini- tial volume has doubled

Explanation:

Given data

Initial temperature of air Ti=300 K

Vf (final volume of air)=2Vi (initial volume of air )

To find

Final temperature

Solution

Since no energy is lost by thermal conduction during the process we categorize  this process as an adiabatic one.Hence we apply;

Where air is predominantly a diatomic gas Y=1.4m

Substitute the given values

So

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
