(i)

Qualities of a good thermometric liquid

1. It must be a good thermal conductor
2. It must be easily seen in the tube
3. It must have a wide temperature range between its transition temperatures
4. It must not wet glass
5. It must not vapourize/condense in the tubing
6. It must have uniform/regular expansion

(ii)

Precautions that must be taken when using a liquid-in-glass thermometer

1. It must be sterilized in an antiseptic
2. The bulb must have to be inserted well into the substance
3. Reading must be taken at eye-level
4. The bulb must not touch the sides or bottom of the container
5. Allow sufficient time for thermal equilibrium to be reached
