DEAR FRIEND

A thermometer is a device that is used to measure the temperature of a body. Common types of thermometers are Medical thermometers, Infrared thermometers, Mercury thermometers, thermocouple thermometers, laboratory thermometers, Bimetallic strip thermometers, Pyrometers, etc.

Thermometer is made of a long narrow glass tube; with a bulb at one end. The narrow tube appears as a continuous silver line; because it is filled with mercury. Mercury is a metal which is in liquid state at room temperature and it readily expands or contracts at the slightest change in temperature.
