A glass bulb of volume `400 cm^(3)` is connected to another bulb of volume `200 cm^(3)` by means of a tube of negligible volume. The bulbs contain dry air and are both at a common temperature and pressure of `20^(@) C` and 1.000 atm, respectively. The larger bulb is immersed in steam at `100^(@) C` and the smaller in melting ice at `0^(@)`. Find the final common pressure.

Options

A. 1.13 atm
B. 1.23 atm
C. 1.43 atm
D. 1.53 atm

Answer
