Why should a clinical thermometer not be washed in hot water?
The idea is based avoiding use of the thermometer when it is reading "higher" than what it is that is being measured. Let's look at what's happening. If we wash a clinical thermometer in hot water, it will respond to that hot water. That will cause the reading to shoot up well above a hundred degrees. If we then try to use it, it will have to "cool down" under the tongue of the person we're using it on. It is actually being cooled by that person. The thermometer will take a relatively long time to reach the temperature of the individual whose temperature is being measured. And this time will vary, but will be longer than it would be for the thermometer to "come up" to temperature. One of the directions for using these thermometers is to first shake it down until it reads less than 95 degrees or so. If you're starting with a thermometer than has just been washed in hot water, you're not going to be able to shake it down per the directions. You'll have to run it under cool water for a bit to cool it so you can use it.
How do you use cherry in a sentence?
My younger sister's favorite phrase seems to be "Prettty please, with a cherry on top." My vanilla shake has a cherry on top.
How do you properly clean and maintain a wash bottle for laboratory use?
To properly clean and maintain a wash bottle for laboratory use, first empty any remaining contents and rinse the bottle with distilled water. Then, fill the bottle with a cleaning solution, such as a mixture of water and detergent, and shake it well. Rinse the bottle thoroughly with distilled water and allow it to air dry before refilling it with the desired solution. Regularly check the bottle for any signs of wear or damage, and replace it if necessary.
Why does soda fizz when you shake it?
When you shake a soda, the carbon dioxide gas that is dissolved in the liquid gets released and forms bubbles, creating fizz.
What happens when you shake soda and then open it"?
When you shake soda and then open it, the carbon dioxide gas that was dissolved in the liquid is released rapidly, causing the soda to fizz and potentially overflow.
What precautions should be taken for using a clinical thermometer?
Before using a clinical thermometer, make sure it is clean and disinfected. Shake it down to below 35°C before using. Place it under the tongue for the recommended amount of time (usually about 3 minutes) without biting down to obtain an accurate reading.
What do you do before taking an axillary temperature?
Shake down the thermometer before using, if the reading on the thermometer is 94.0º F or above.
Why does the clinical thermometer have a constriction?
Quote: When the temperature falls, the column of mercury breaks at the constriction and cannot return to the bulb, thus remaining stationary in the tube. After reading the value, the thermometer must be reset by repeatedly swinging it sharply to shake the mercury back through the constriction. Unquote.
Why we shouldn't shake a Laboratory thermometer?
Shaking a laboratory thermometer can cause the mercury inside to separate, leading to inaccurate temperature readings. It can also damage the delicate capillary tube inside the thermometer, affecting its overall precision and reliability. It's best to handle laboratory thermometers with care to ensure their accuracy and longevity.

Why clinical thermometer is jerked before using it again?
If you have an old thermometer that has mercury, then the shaking makes all of the mercury flow to the bottom of the thermometer. Then, you can get a better reading. The current digital ones work differently. Thermometers used for taking people temperatures are a special kind that go up with heat but don't go down with cold. So you have to shake a thermometer before taking your temperature to make the reading go down below your own temperature. Then the thermometer can go up again to read your temperature.
Why is it not necessary shake the digital or a laboratory thermometer before using it?
Digital and laboratory thermometers do not require shaking because they measure temperature electronically or through physical contact with the object being measured. Shaking is necessary for traditional liquid-in-glass thermometers to ensure uniform mixing of the liquid, but modern digital or laboratory thermometers do not have this requirement.
Why is there a need for us to shake the clinical thermometer prior to each use?
If the clinical thermometer is a mercury based thermometer, it needs to be shaken down prior to each use. This is because there is a pinch point between the mercury reservoir bulb and the capillary tube, to ensure that the mercury does not shrink back into the bulb after the temperature has been taken. The mercury has therefore to be shaken back into the bulb before another measurement can be made. One should note that in many countries use of mercury based clinical thermometers is now discouraged (because mercury is toxic) and electronic thermometers are used in stead - these do not need shaking.
How do you use the clinical theamometer?
1.shake the thermometer vigorously so that the murcery goes below the normal mark 2.keep the rhermometer either in the armpit or under the tongue of the person whose temperature is to be taken 3.wait for 2 minutes 4.take out the thermometer and read the mark where the silver mark of mercury ends
How can I reset a Galileo thermometer?
To reset a Galileo thermometer, gently shake it or rotate it until all the glass bulbs are at the bottom. This will recalibrate the thermometer and allow it to accurately display the temperature.
How should a thermometer be dried properly?
To dry a thermometer properly, gently shake off any excess liquid and then use a soft, clean cloth to wipe it dry. Ensure that the thermometer is completely dry before storing it to prevent damage.
What is a test tube used for in a laboratory?
it is used fr a lot of things like to shake things
