Kinetic particle model of matter — practice question

Fig. 5.1 presents diagrams showing how molecules are arranged in the three states of matter, together with descriptions of the way the molecules move.
(a)[4]

On Fig. 5.1, draw a line: link each arrangement of molecules to the correct state of matter then link each state of matter to the correct description of the movement of molecules.

(b(i))[1]

State how the increase in temperature affects the motion of the air molecules in the tyre.

(b(ii))[1]

State how the rise in temperature affects the pressure of the air in the tyre.

(c(i))[2]

Add the omitted labels to Fig. 5.2.

(c(ii))[1]

The thermometer in Fig. 5.2 is designed to measure temperatures in the range from $0 ^{\circ}\text{C}$ to $100 ^{\circ}\text{C}$. State the name of a suitable liquid for use in this thermometer.

(c(iii))[2]

Describe and explain the changes in the thermometer in Fig. 5.2 when the temperature of the liquid increases.
