If `20 cm^(3)` gas at `1 atm` is expanded to `50 cm^(3)` at constant `T`, then what is the final pressure

A

`20xx(1)/(50)`

B

`50xx(1)/(20)`

C

`1xx(1)/(20)xx50`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
At constant `T, P_(1)V_(1)=P_(2)V_(2)`
`1xx20= P_(2)xx50, P_(2)=(20)/(50)xx1`
