One litre of a gas weights 2 g at 300 K and 1 atm pressure. If the pressure is made 0.75 atm at which of the following temperature will one litre of the same gas weight one gram ?

A

450 K

B

600 K

C

800 K

D

900 K

Text Solution

Verified by Experts

The correct Answer is:
A
`(P_(1)V_(1))/(P_(2)V_(2))=(n_(1)T_(1))/(n_(2)T_(2))` [Same gas `:.` molar mass is same ]
`(P_(1)V_(1))/(P_(2)V_(2))=(W_(1)T_(1))/(W_(2)T_(2))`
