Basic Gas Laws Send me an email and I will send you the Powerpoint of this. Boyle s Law Deals with the relationship between the pressure on a gas and the volume it occupies as long as the temperature is constant Characteristics of Gases Expansion Expansion. A gas will expand to fill its container. Low density Low density. Gases possess low levels of matter per unit volume.
Pressure is a consequence of the moving gas molecules striking the sides of the container.
Pressure results from the collision of particles with the sides of a container. As the volume of a confined gas decreases, the pressure of the gas increases. As the volume of a confined gas increases the pressure decreases. The relationship between pressure and volume is referred to as an inverse relationship. If you begin with some pressure, it will have some volume.
