Please answer this. Lesson is heat..
Dear Student,
(5.)
A Thermometer is a device used to measure the temperature or degree of hotness of an object or living being. A thermometer consists of a temperature sensor that senses a physical change with temperature, and a means of converting this physical change into a numerical value.
The first figure is of Clinical Thermometer and the second one is of laboratory thermometer.
Uses and description:-
Clinical thermometer
This thermometer is used to measure the human body temperature. It is a mercury based thermometer and has a temperature range from 35oC to 42oC. The sensor in this is the mercury present in the bulb portion which is placed below the tongue for measuring the temperature. The bulb is connected to the long and narrow tube with a scale that gives the numerical value of the temperature. Mercury in the bulb on heating expands and moves up the scale. The thermometer contains a kink near the bulb that does not allow the mercury level to fall in the thermometer and allows for reading of the correct temperature when it is removed from the mouth.
Laboratory thermometer
The thermometer is similar to the clinical thermometer except that it can measure larger temperature ranges. The thermometer is either mercury or alcohol-based. This thermometer does not contain a kink and therefore needs to be within the object whose temperature is being measured. It is used for measuring temperatures other than the human body temperature. It ranges from -10˚C to 110˚C. Laboratory thermometers are designed for lab purposes such as checking boiling point, freezing point, or temperature of other substances.
6.
We should not use a clinical thermometer for cooking purposes. Because Thermometers used to measure human body temperature do not read high enough temperatures for cooking. They are not manufactured to withstand temperatures above 106 °F (41.1 °C) as their temperature range from 35oC to 42oC.
