Boyle's law developed by Robert Boyle in 1662, states that if we keep the temperature of a gas constant in a sealed container. Its pressure (P) varies inversely with its volume (V). In other words at any given temperature. If we pressurize a gas its volume will be reduced proportionately to the pressure change. If we increase the volume of a gas its pressure will increase.
I am not sure what you mean by the steps, but I can help you identify a Boyle's Law problem, and tell you how to solve it.
Boyle's Law is that Pressure, P is inversely related to volume, V at constant temperature and number of moles. The mathematical relationship is
which rearranges to
You can tell a problem will be a Boyle's law problem, if there is a change in pressure or volume and it asks you about the other.
For example, you could be asked the following:
If a gas at atmospheric pressure, has its container expand to three times its volume, what is the new pressure.
