A gas sample has a volume of 1.5 liters when the thermometer on the wall reads 25°C. What volume will it occupy if it is warmed to 100°C?
A gas has a pressure of 655 mmHg at [math]25 degC[/math]. To what temperature must it be heated in order to raise its pressure to 825 mmHg?
If you were to apply heat to a gas sample with a volume of 2.0 liters starting from 26°C and stopping at 100°C, what would be its volume when you stop heating the sample?
