Answer:

Temperature is a physical quantity that expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder or hotter. Temperature is measured with a thermometer.

Explanation:

There are different types

Digital thermometers. ...

Ear (or tympanic) thermometers. ...

Infared thermometers. ...

Strip-type thermometers. ...

Mercury thermometers.

Digital thermometers work by using heat sensors that determine body temperature. They can be used to take temperature readings in the mouth, rectum, or armpit. When assessing digital thermometer readings, keep in mind that armpit (axillary) temperature runs about ½ to 1°F (0.6°C) cooler than oral readings.

Answer:

Ans. A reliable measure of the hotness of an object is called its temperature. It

is measured by a device called thermometer.

There are two types of thermometer:

(i) Clinical thermometer: The thermometer that measures the

temperature of our body is called clinical thermometer. It consists of

a long, narrow, uniform glass tube. It has a bulb at one end which

contains mercury. Outside the bulb a small shining thread of mercury

can be seen. There is also a scale on the thermometer. The scale used

in it is the Celsius scale, indicated by °C. A clinical thermometer reads

temperature from 35°C to 42°C.

(ii) Laboratory thermometer: This type of thermometer is used to

measure the temperature of different objects in laboratories. It is

made of a thin glass tube sealed at one end and a bulb with mercury

at the other end. The portion of the capillary tube above the bulb is

graduated in degrees usually from -10°C to 110°C.
