In Joly’s constant volume gas thermometer, why mercury is added in glass bulb?

Solution

The volume changes when the temperature of the bulb is changed. Therefore the volume of gas in the bulb will no longer be constant. To nullify the change in volume of glass bulb due to change in temperature, the mercury is added in the bulb of the thermometer.
