A 60.0 mL volume of a gas was found to have a pressure of 2.0 atm at 25°C. What will be the new volume if the pressure is changed to 0.50 atm at constant temperature?
The second volume will be 240 mL.
This is an example of Boyle's law, which states that the volume of a given amount of a gas kept at constant temperature varies inversely with the pressure. In other words, if the volume increases, the pressure decreases, and vice versa. The equation to use is
Rearrange the equation to isolate
