Question

give two reasons why mercury is used in thermometer

Answer 1

Following are the reasons why we use mercury in thermometer

1: It doesn't wet the glass, so you don't get inaccurate readings if the temperature is falling.

2: It is a metal, so it's a good conductor of heat. This means that it reacts quickly to changes of temperature.

3: It is very reflective, so it's easy to see and to read accurately.
