How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
What is advantages and disadvantages of clinical thermometer?
Clinical thermometers, also known as medical thermometers, are used for measuring human body temperature. They have kinks at one end which prevent the fluid from flowing back before the readings have been taken. They offer accurate and easy-to-read recordings, in addition they are easy to clean, to carry around and to store.

What are the advantages and disadvantages of using alcohol in a thermometer?
The advantages are:They are cheap.They can be seen clearly as they are in red in color.They are thermomatric liquids.The disadvantages are:They wet the surface.They have less surface tension.They have less density.
What are the disadvantages of shielding a thermometer?
Shielding a thermometer may have some disadvantages, including: Inaccurate readings: If the thermometer is shielded improperly, it may affect the temperature readings by blocking heat or cooling that should be reaching the thermometer. Slow response time: If the thermometer is shielded too much, it may not be able to respond to temperature changes quickly, which can lead to inaccurate readings or delayed readings. Uneven temperature distribution: If the thermometer is shielded, it may not be able to measure the temperature of the surrounding environment accurately, which can lead to uneven temperature distribution. Difficulty in calibration: Shielding the thermometer can make it difficult to calibrate and maintain, which can affect its accuracy over time. Increased cost: Adding a shield to a thermometer may increase the cost of the device and add complexity to its design, which can make it more expensive to produce and maintain. In summary, while shielding a thermometer may be useful in certain circumstances, it can also have some drawbacks that may affect the accuracy and reliability of temperature readings. It is important to consider the specific application and environment before deciding whether to shield a thermometer or not.
