Helium gas at `300 K` is shifted from a vessel of `250 cm^(3)` to a vessel of `1 L` capacity. The pressure of gas will

Options

A. become four times
B. becomes double
C. decrease to half of the original value
D. decrease to `1//4th` of the original value

Answer

D

Explanation

`250 xx P_(1) = 1000 xx P_(2)`
`:.` the pressure `P_(2) = (250)/(1000) P_(1) = 1//4 P_(1)`
