Fig. 9.1 shows the molecular structure of a solid and a gas. In the middle box of Fig. 9.1, draw a sketch to represent the molecular structure of a liquid.
Explain why a gas is easier to compress than a solid.
The temperature of a liquid-in-glass thermometer rises. State two ways in which the molecules of the liquid in the thermometer are affected.
Fig. 9.2 shows the liquid-in-glass thermometer. There is no scale on the thermometer. State what is meant by the ice point and the steam point.
Describe how the ice point and the steam point are used to mark the thermometer.
Explain how increasing the mass of liquid in the bulb affects the range of a liquid-in-glass thermometer.
Explain how increasing the diameter of the narrow tube affects the range of a liquid-in-glass thermometer.
