Question

A one litre sphere and a two litre sphere are connected with a capillary tube of negligible volume. They contain an ideal gas at 27⁰C at a pressure of 100cm of Hg. Keeping the temperature of one litre sphere constant at 27⁰C, if temperature of two litre sphere is increased to 127⁰C, then the final pressure is

Moderate

Solution

$By coservation of moles \frac{{PV}_{1}}{T_{1}} + \frac{{PV}_{2}}{T_{1}} = \frac{P^{1} V_{1}}{T_{1}} + \frac{P^{1} V_{2}}{T_{2}}$
