what the thermometer
Answers
Answer:
a device used to measure body temperature.
The different type of thermometer have different properties and roles according to the situation like glass thermometer is basically used for measuring the temperature of the body, and clinical thermometer is used as a specially designed and calibrated thermometer to measure our body temperature such as a thermometer is known as clinical or doctors thermometer in laboratory thermometer is mainly used in Laboratories to measure the degree or to measure the temperature of that substance is in which temperature...
We find that many of the physical properties like thermal expansion , pressure and volume of different material change with temperature in a regular and systematic manner. We can therefore used these properties as a way of measuring temperature. The simplest thermometer which which all are familiar in the mercury in glass thermometer. It is based on the thermal expansion of the Mercury this thermometer consists of a narrow capillary tube of Glass that is closed at its upper end and has bulb at its lower end the bulb is filled with Mercury inside the capillary tube we can see a small shining thread of America is the Mercury present in Ball of a thermometer expand when heated the extent of its expansion and there for the length of the Mercury thread in the capillary tube depends on the extent of the heating thermometer this in turn depends on the temperature of the object with which the thermometer bulb has been put in the contact. The length of the Mercury thread in the thermometer can thus give a some measure of a temperature of a body , this whole process contains for a Glass Thermometer. This is the most common thermometer used in home and at other places.
