"Gas Law Variables" It describes volume, pressure, and amount of gas.

Volume: All gases have to be enclosed in a container that can be sealed with no leaks. The space in that container is the volume. In Chemistry, volume is usually measured in liters or milliliters. -Whenever units of volume are used, use them all the way through the problem. In Boyle's law, the volume is a variable. This means that the container involved in the experiment has a movable wall. When the volume goes up, …

…be a symbol "P". There are three units of pressure used in Chemistry. This is a problem because you have to learn to use all three units. · Atmosphere (symbol: atm) · Millimeters of mercury (symbol: mm Hg) · kiloPascals (symbol: kPa) Standard pressure is defined as one atm, 760.0 mm Hg, or 101.325 kPa Amount of Gas: The amount of gas measured in a container is measured in moles or in grams. When using moles, the symbol is "n".
