Motion of Particles in a Gas
The motion of particles in a gas is constant and random. This means that all of the particles are always moving and that there is no pattern to their movement. Temperature of gas is related to the average kinetic energy of the particles/molecules. Earlier we described temperature as how much a particle moves, the greater the temperature the greater the kinetic energy. We can see that this description is useful here as well. For a given gas at a constant volume (so its container does not change), a changing temperature can change the pressure.
How Does Temperature and Pressure Affect the Motion of a Particle?
- If the temperature is increased, what happens to the motion of the particles of a gas if the volume is kept the same?
- If the temperature is increased, what happens to the pressure of a gas if the volume is kept the same?
