A sample of gas has a volume of 0.2 L, measured at 1 atm pressure and `0^@`C. At the same pressure but at `273^@`C, its volume becomes

Options

A. 0.1 L
B. 0.4 L
C. 0.4 L
D. 0.6 L

Answer

b

Explanation

`V_(1) =0.2L, P_(1) = 1 atm, P_(2) = 1 atm, T_(1) = 273 K, T_(2) = 546 K`
`(P_(1)V_(1))/T_(1)= (P_(2)V_(2))/T_(2)`
`therefore V_(2)=(1 xx 0.2 xx 546)/(1xx273) = 0.4L`
