Fig. 6.2 shows that more ice cubes have been added to the glass of water. Fig. 6.2 The ice cubes reduce the temperature of the water. The scale on the liquid-in-glass thermometer shows this decrease in temperature. Explain this action of the liquid-in-glass thermometer. Use ideas about particles in your answer.

What examiners said
Many candidates could describe the stronger attractive forces in a solid. Some candidates were able to describe the particles in a gas as moving freely but fewer referred to particles in a solid being in a fixed arrangement. These ideas needed to be combined to gain full credit.
