The temperature of a gas at pressure P and volume V is `27^(@)C`. Keeping its volume constant. If its temperature is raised to `927^(@)C`, then its pressure will be

A

2p

B

3p

C

4p

D

6p

Text Solution

Verified by Experts

The correct Answer is:
C
By Charle.s law, `(p_(1))/(T_(1)) = (p_(2))/(p_(2))`,
`therefore T_(1) = 27 + 273 = 300 K` and `T_(2) = 927 + 273 = 1200 K`
`p_(2) = (p_(1)T_(2))/(T_(1)) = p xx (1200)/(300) = 4p`
`p_(2) = 4p`
