Pressure and Volume (cont’d) Boyle’s law holds as long as the temperature of the gas remains the same and the amount of gas does not change. A gas whose behavior follows predicted pressure/volume relationships is called an ideal gas .

We can rearrange the equation that relates volume and pressure: For two different sets of V and T values we can write: = constant V T as before, same constant for all values of pressure and volume (as long as amount of gas and temperature stay the same) = constant V 1 T 1 = constant V 2 T 2 = V 1 T 1 V 2 T 2
