Are The molecules of the liquid inside a thermometer increase in speed when the thermometer is cooled.?
No, the molecules of the liquid inside a thermometer do not increase in speed when the thermometer is cooled. Instead, they lose energy and slow down, causing the liquid to contract and move down the scale. When the thermometer is heated, the molecules gain energy and speed up, leading to expansion of the liquid.
Why can a mercury thermometer be used only at high temperatures?
A mercury thermometer can go down to -30 deg C
Why doesn't the liquid in the thermometer move when you turn it upside down?
The liquid in a thermometer does not move when turned upside down because of the properties of the liquid used (usually mercury or alcohol) and the vacuum-sealed tube design of the thermometer. This design prevents the liquid from freely moving when the thermometer is inverted.
Why wouldn't you take a mercury in glass thermometer with you to south pole?
If I only had those 2 choices... I would use ALCOHOL since Mercury freezes at -38.72° Celsius. The North Pole can get down below -50° Celsius. Ethanol (alcohol) freezes at -114 ° Celsius Methanol (alcohol) freezes at -97.8° Celsius
Would Earth's atmosphere liquefy or freeze if the Sun went out?
Eventually, it would cool down until it freezes.
Why does sitting in a cold bathtub cool your body down?
It cools your body down because the water is so cold that the temperature in you u body goes like a thermometer.
What would be a cool down activity?
A cool down activity could be gentle stretches.
Why does the liquid in a thermometer go down before the temperature is taken?
It does not by itself. It must be shaken down. The liquid is mercury, which is very heat-expansive, i.e. it changes its volume noticeably and quickly depending on its temperature. The warmer, the larger the volume. That's why it's used in thermometers. However, thermometers are built so that the mercury does not go down by itself to enable taking precise readings (otherwise, it would fall quickly immediately after the thermometer is removed from the body). So, the thermometer must cool and the contracted but vacuum-stuck mercury must then be shaken down to take another measurement.
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.
Can Chuck Norris cool down the sun?
Chuck Norris would never cool down the sun. Its Chuck Norris approved.
What happens to the mercury in the thermometer when the air is cool?
In a mercury thermometer, the level of mercury falls as the temperature of the air around it cools.A mercury thermometer has a bulb of mercury at the bottom and a thin tube above it with markings in Celsius degrees or Fahrenheit degrees. When the temperature warms, the mercury expands and rises up the tube. When the temperature cools, the mercury contracts and shrinks back toward the bulb at the bottom.
How did dinosaurs keep cool?
they would lay down in water
What is temperature and how a thermometer measures it?
temperture is how much or how many degree's it is and a thermometer measures it by sticking it in a place like water or something else and then the bar would go up or down like DUHHH
Why the alcohol level in a thermometer goes down when it's cold?
When the temperature drops, the alcohol in the thermometer contracts and takes up less space. This results in the alcohol level appearing to go down in the thermometer.
How is ethanol harnessed?
Ethanol is typically produced through the fermentation of sugars in crops such as corn or sugarcane. These crops are broken down into sugars, which are then fermented by yeast to produce ethanol. The ethanol is then separated from the mixture through a distillation process.
What would happen if you used a clinical thermometer to measure a hot drink?
Using a clinical thermometer to measure a hot drink can result in inaccurate readings as most clinical thermometers are not designed to measure temperatures of hot drinks. This can damage the thermometer and give false temperature values. It is recommended to use a thermometer specifically designed for measuring high temperatures in such cases.
How would tea cool down in a metal cup?
Tea in a metal cup would cool down relatively quickly, since the metal cup wall conducts heat very well.
