Answer: The correct answer is 'temperature will get doubled that is option D.

Step-by-step explanation:

Suppose the volume of the bubble is V, at temperature T and Pressure exerted by atmosphere P.

When bubble is blown with more air until the volume doubles the initial volume:

The new volume of the bubble = V'=2V

The new Temperature of the air inside the bubble will change to T'.

And the atmospheric Pressure remains same.

According Charles law:

$Volume\propto Temperature$ (At constant Pressure)

(V_1)/(T_2)=(V_2)/(T_2)

(V)/(T)=(V')/(T')

T'=(2V* T)/(V)=2T

So, this means that temperature will get 2 times the initial temperature of the gas.

Hence, the correct answer is 'temperature will get doubled that is option D.
