Two glass bulbs with equal volume are connected by a narrow tube and filled with a gas at $0^{\large\circ}C$ and pressure of $76\;cm\; Hg$ . One of the bulb is then placed in a water bath maintained at $62^{\large\circ}C$. What is the new value of the pressure inside the bulbs? The volume of the connecting tube is negligible.

Question

$(a)\;23.75 cm\; Hg\qquad(b)\;83.75 cm\; Hg\qquad(c)\;29.75 cm\; Hg\qquad(d)\;30.76 cm\; Hg$
