5.15 Temperature and Speed

5.15 understand that an increase in temperature results in an increase in the speed of gas molecules

What is Temperature?

Temperature is a measure of the average kinetic energy of the particles in a substance. What this means is that as we increase the temperature of a gas the particles have more kinetic energy and therefore move around at a greater speed and collide with each other more often, it also means that they collide with the walls of the container more often and with a greater force, so looking back at the previous video [see 5.12] an increase in force and a constant surface area results in an increase in pressure \ increase temperature (of a gas) => increased pressure (of the gas).
