What volume will a sample of gas occupy at `87^(@)C` and `720 mm` pressure if its volume at `27^(@)C` and `750 mm` pressure is `250 mL` ? |

Answer» 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` |
