Physics - Heat & Thermo Question with Solution | TestHub

A glass bulb of volume 100$c{m}^3$is connected by a narrow tube of negligible volume to another bulb of 300$c{m}^3$. The apparatus is filled with air at a pressure of 76 cm of mercury and a temperature of$12^{\circ }$C, and then sealed. The smaller bulb is then immersed in melting ice whilst the larger bulb is placed in boiling water. Calculate the fraction of the total mass of air in the larger bulb, ignoring the expansion of the bulbs.
