Ques. → At 27°C , 2 moles of an ideal monotonic gas occupy a volume V. The gas then expands adiabatically and the volume changes to 2V. Find the final temperature of the gas.

Solution → Here , we shall just use the equation of Adiabatic change!

★The Equation is as follows -

$= > t2v2 {}^{( \gamma - 1)} = t1v1 {}^{( \gamma - 1)}$

•°• We have ,

Temperature t 1 = 27°C = 300 K

Putting values in the formula ,

$= > t2 = t1 (\frac{v1}{v2} ) {}^{ \gamma - 1} \\ \\ = > 300 \times ( \frac{1}{2} ) {}^{ \frac{5}{3} - 1}$

•°• The final temperature of the gas is $<b> <u> 189 K </b> </u>$ !!
