A soap bubble,blown by a mechanical pump at the mouth of a tube, increases in volume, with the time, at a constant rate. The graph that correctly depicts the time dependence of pressure inside the bubble is given by :

A soap bubble is blown with the help of mechanical pump at the mouth of a tube. The pump produces a cartain increase per minute in the volume of the bubble, irrespective of its internal pressure. The graph between the pressure inside the soap bubble and time t will be

The soap bubble formed at the end of the tube is blown very slowly. Draw the graph between excess of pressure inside the bubble with time.
