500 mL of nitrogen at `27^(@)C` is cooled to `-5^(@)C` at the same pressure. The new volume becomesA. 326.32 mLB. 446.66 mLC. 546.32 mLD. 771.56 mL

Answer» Correct Answer - B
Initial volume, `V_(1)=500" mL"`
Initial temperature,
`T_(1)=27^(@)C=27+273=300K`
Final temperature,
`T_(2)=-5+273=268K`
`V_(2)=?`
`(V_(1))/(T_(1))=(V_(2))/(T_(2))`
`V_(2)=(V_(1)T_(2))/(T_(1))=(500xx268)/(300)`
`=446.66" mL"`
