1
New cards
Motion of molecules of a gas
constant random motion
2
New cards
What is the temperature of the gas related to
the average kinetic energy of the molecules
3
New cards
What does changing the temperature of a gas do (if held at constant volume)
changes the pressure exerted by the gas
4
New cards
Why does increasing temperature of a gas, increase the pressure exerted
provides more energy to molecules, increases the speed at which the particles move, increasing number of collisions with walls per second, therefore increasing pressure
