Explain the used of a maximum minimum thermometer is used?
i dont no just leave me alone
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 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.
Why is it important for laser and radar guns to have regular calibration?
Law enforcement agencies regularly calibrate their radar guns to avoid disputes in court. Laser speed detection devices are actually so accurate that there is little need to calibrate them on a regular basis.
Explain why it is necessary to have a standard thermometer?
to make the same type of measurement around world so that there is a universal when measuring certain substances.
Why is it important to calibrate a bimetallic thermometer every day?
Accuracy is lost when thermometers are bumped or dropped.
Why is important to calibrate a bimetallic thermometer every day?
Accuracy is lost when thermometers are bumped or dropped.
When you calibrate a thermometer you should place it in an ice bath water and ice mixed together and the temperature should be?
32
Why it is necessary to calibrate a thermometer and a volumetric glassware?
In order to get a more precise and accurate reading.
Is it important to calibrate your touch screen?
If you feel the touch insensitivity is better to calibrate your touch screen.
Why it is important the luquid in the thermometer has uniformly?
It is important for the liquid in the thermometer to be uniform for accurate measurements. If a thermometer is not calibrated properly, it will detect measurements in temperatures that are inaccurate.
why is it important to calibrate a pH meter before you used it?
checking ph
How do you calibrate a thermometer?
You first put ice into a cup then add cold water, then stir. You then wait until it is 0 degrees ( which will take about 5 minutes ) then you put the thermometer in and make sure it is 0 degrees celsius. Then boil water and put a thermometer in and make sure it's 100 degrees celsius.
Why do you need to calibrate?
Calibrating a microscope simplifies the process of obtaining quick and accurate measurements. It is important to calibrate the microscope for each object you plan to view with the lens.
How do you calibrate a thermometer into degrees Celsius?
The end points are ice which is zero celsius, and boiling water which is 100 celsius. Divide the distance between into 100 equal degrees.
Explain how you would use a wet bulb thermometer and a dry bulb thermometer to find the relative humidity?
the wet bulb is cooler
Explain how an ordinary glass fever thermometer is designed?
By using glass.
