Answer:
Thermometer is device for measuring temperature of any body. It consists of two main parts.
Temperature sensor (mercury bulb, in case of mercury thermometer)
Display device: where the temperature is shown by any physical change (expansion in volume in mercury thermometer)
In mercury thermometer have a mercury bulb and a capillary. On application of heat, mercury increases through capillary. Expansion is proportional to the heat transferred to the mercury bulb. A visible scale is fixed of the capillary, which represent the temperature.

Answer:
A thermometer is a device used for measuring temperature. ... A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin.
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
