Two glass bulbs of equal volume are connected by a narrow tube and are filled with a gas at 0^@C and a pressure of 76cm of mercury. One of the bulbs is then placed in melting ice and the other is placed in a water bath maintained at 62^@C . What is the new value of the pressure inside the bulbs? The volume of the connecting tube is negligible.
