Given
`V_(1)=250 mL`
`T_(1)=27^(@)C` or `300.15 K`
`P_(1)=750 mm`
`V_(2)=?`
`T_(2)=87^(@)C` or `360.15 K`
`P_(2)=720 mm`
`:. (P_(1)V_(1))/(T_(1))=(P_(2)V_(2))/(T_(2))`
or `V_(2)=(P_(1)V_(1))/(T_(1))xx(T_(2))/(P_(2))=(750xx250)/(300.15)xx(360.15)/(720)=312.5 mL`
`:. Change in volume =V_(2)-V_(1)=170-152=18 mL`
