If the pressure of 1.50 L of hydrogen gas at 100°C decreases from 0.500 atm to 0.115 atm, what is the final volume? Assume temperature remains constant.

In an underground gas reserve, a bubble of methane gas (CH₄) has a volume of 45.0 mL at 1.60 atm pressure. What volume, in milliliters, will the gas bubble occupy when it reaches the surface where the atmospheric pressure is 744 mmHg, if there is no change in temperature?

Which of the following correctly describes the relationship between variables in Boyle's Law?

What was the original temperature of a gas, in °C, if the volume changed from 1.00 L to 1.10 L and the final temperature was 255.0 °C, assuming constant pressure?
