All of the above

Vedclass · Answer

(D) When the water is heated,the following changes occur:$1$. The saturated vapour pressure of water increases with temperature,which exerts more pressure inside the bubble,causing it to expand.$2$. As the temperature increases,the kinetic energy of the air molecules inside the bubble increases,leading to an increase in their root mean square velocity,which increases the pressure exerted by the air on the bubble walls.$3$. The surface tension of water decreases as the temperature increases. Since the excess pressure inside a bubble is given by $P = 2T/r$,a decrease in surface tension $(T)$ allows the bubble to expand for a given internal pressure.Therefore,all the given factors contribute to the increase in the size of the bubble.
