Okay, in this question we are working with partial pressures and partial pressure refers to the pressure of a gas in a mixture.
00:22
So it is a partial pressure of the entire pressure.
00:26
This is the pressure of just the gas, an individual gas.
00:31
Pressure results from collisions of the gas particles with the walls of the container.
01:03
More collisions, of course, would be equal to a higher partial pressure.
01:18
Okay, so since the gases in this mixture are all at the same temperature, because they're all in the same container, so they're going to all have the same temperature, which means they all have the same average kinetic energy, because kinetic energy is a measure of temperature.
01:48
Our temperature measures that average kinetic energy.
01:50
All right, so they all have the same average energy of motion...
