An open flaskh has Helium gas at 2 atm and `327^@C`. The flask is heated to `527^@C` at the same pressure. The fraction of original gas remaining in the flask is 

A

3/4

B

1/4

C

`1//2`

D

2/5

Text Solution

Verified by Experts

The correct Answer is:
A
`n_1T_1 = n_2T_2 , n_1 xx 600 = n_2 xx 800`
`n_2 = 3/4 n_1`.
