Q2 contd.
b) The diagram below shows the model that a science teacher used to show
her students that there is a link between the temperature of a gas and the
speed of the gas particles.
The ball-bearings represent the gas particles. Switching the motor on makes
the ball-bearings move around in all directions.

Q2 contd.
(b) (i) How is the motion of the ball-bearings similar to the motion of the
gas particles?
(1 mark)
(b) (ii) The faster the motor runs, the faster the ball-bearings move.
Increasing the speed of the motor is like increasing the temperature of a
gas.
Use the model to predict what happens to the speed of the gas particles
when the temperature of a gas is increased.
