Gas pressure
If the The volume of a three-dimensional shape is a measure of the amount of space or capacity it occupies, eg an average can of fizzy drink has a volume of 330 ml. of a container with a gas inside stays the same, the pressure of a gas increases as its A measure of the average kinetic energy of particles in a substance. increases.
As a result, the gas particles will be travelling faster and will collide with the walls of the container more frequently, and with more A push or a pull. The unit of force is the newton (N)..
This means that there is a A relationship tells us how two or more variables work together, eg the relationship between resistance, voltage and current is: resistance = voltage ÷ current. between Force exerted over an area. The greater the pressure, the greater the force exerted over the same area. and temperature. If a pressure gauge is connected to a flask of air and the flask is heated, a graph of pressure against temperature can be produced.
