A sample of gas at room temperature is placed in an evacuated bulb of volume `0.51 L` and is found to exert a pressure of `24 kPa`. This bulb is connected to another evacuated bulb whose volume is `0.63 L`, and the gas is allowed to fill both bulbs. What is the new pressure of the gas at room temperature ?

A

`9 kPa`

B

`11 kPa`

C

`7 kPa`

D

`5 kPa`

Text Solution

Verified by Experts

The correct Answer is:
B
At constant `n` and `T`, we can apply Boyle's law:
`p_(1)V_(1) = p_(2)V_(2)`
`(24 kPa) (0.51 L) = p_(2)(0.51 L + 0.63 L)`
`p_(2) = 11 kPa`
