Answer 1

Explanation:

A. Mercury expands and contracts as the temperature rise or falls.Bulb thermometers follow the simple principle that liquids change their volumes relative to their temperature. As temperatures rise, the mercury-filled bulb expands into the capillary tube. Its rate of expansion is calibrated on the glass scale.

B. We know that temperature of ice is 0 degree C . If we put thermometer on ice we will observe mercury comes down and mark the lowest point on scale.
