A one litre spherer and a two litre sphere are connected with a capillary tube of nefligible volume. They contain an idel gas at `27^(0)C` at a pressure of `100cm` of `Hg`. Keeping the temperature of one litre sphere constant at `27^(0)C`, if temperature of two litre sphere is increased to `127^(0)C`, then the final pressure is

Options

A. `110 cm` of `Hg`
B. `120 cm` of `Hg`
C. `150 cm` of `Hg`
D. `200 cm` of `Hg`

Answer

B

Explanation

`(PV_(1))/(T_(1)) + (PV_(2))/(T_(1)) = (P^(1)V_(1))/(T_(1)) + (P^(1)V_(2))/(T_(2))`
