What is the principle of thermometer?
These liquid thermometers are based on the principal of thermal expansion. When a substance gets hotter, it expands to a greater volume. Nearly all substances exhibit this behavior of thermal expansion. It is the basis of the design and operation of thermometers.
What is the main function of thermometer?
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.
What are parts of thermometer?
The main parts of a mercury thermometer are the capillary, the bulb, the scale, and the expansion chamber.
- Spherical Bulb. The bulb is the lowest part of the thermometer, which has a spherical shape.
- Capillary Tube.
- Expansion Chamber.
- Scale Lines.
- Safety Precautions.
Thermometer and Its Types. 1. Thermometers: • Body temperature is a measurement of the amount of heat in the body. • The balance between heat produced and heat lost is the body temperature. • The normal adult body temperature is 37 degrees Celsius.
What is a platinum wire thermometer?
Platinum Wire Thermometers These are based on the variation of electrical resistance due to temperature Resistance of a metal wire increases with increase in temp. Rt = R0 ( 1 + α t) Range of temp they can measure is from -260 C to 1700 C Temp sensor or material is a coil of fine platinum wire 19 20.
What is the function of mercury in thermometer?
Mercury in clinical thermometers contract when in contact with coldness and expand when in contact with heat. Therefore, indicating the measure of temperature. 2. Thermometers: • There is a normal range in which a person’s body temperature may vary and still be considered normal.
What is the normal range of a thermometer?
Thermometers: Mercury in clinical thermometers contract when in contact with coldness and expand when in contact with heat. Therefore, indicating the measure of temperature. Method Normal Ranges Oral 36.4°C to 37.2°C Rectal 37°C to 37.8°C Axillary 35.9°C to 36.7°C 4.
