One litre of helium gas at a pressure of 76 cm-Hg and temperature `27^@C` is heated till its pressure and volume are doubled. The final temperature attained by the gas is

A

`900^@`

B

`927^@`

C

`627^@`

D

`327^@`

Text Solution

Verified by Experts

The correct Answer is:
B
`(P_(1)V_(1))/T_(1) = (P_(2)V_(2))/T_(2)`
`(76xx1)/300 = (2(76)xx2xx1)/T_(2)`
`therefore T_(2) = 1200K or 927^@C`
