Q2 Higher AQA-PH1FP-QP-Jan12 Q5 5 (a) The diagrams show the arrangement of the particles in a solid and in a gas. Each circle represents one particle.

Q2 contd. 5 (a) (i) Complete the diagram below to show the arrangement of the particles in a liquid.(2 marks) Version 2.0 Copyright © AQA and its licensors. All rights reserved. 5 (a) (ii) Explain, in terms of the particles, why gases are easy to compress (2 marks)

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. Version 2.0 Copyright © AQA and its licensors. All rights reserved.

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.
