Explanation:
Mercury, like most materials, expands with increasing temperature and contracts with decreasing temperature. As the temperature of the bulb increases, the volume of the enclosed mercury increases, causing the surface of the mercury to move farther from the bulb.

Answer:
A thermometer measures temperature through a glass tube sealed with mercury that expands or contracts as the temperature rises or falls. The tiny size of the bulb and micro-fine size of the tube help the mercury reach the temperature of what it is measuring very rapidly.
