Why does the substance in the thermometer go up when it gets hot?
The substance inside a thermometer expands when it gets hot due to increased kinetic energy of its molecules. This expansion causes the liquid to rise up the column, indicating a higher temperature reading.
Is it a physical or chemical change when the liquid mercury in a thermometer expands as it is heated?
physical change
What is difference between a clinical and a laboratory thermometer?
A lab thermometer normally is very long and has a wide range of measurement with uniform degrees spread out over the distance and has a mark showing how far into the measured substance it go to get accurate measurements.A clinical thermometer has a larger bore at the bottom where the contents can expand without measurement occuring then a tiny bore where the degrees are spread out at the body temperature. Thus at room temp, all the liquid is down in the big area and only as it gets up to 95 degree or so is the liquid expanded in the reading area. This allows the thermometer to be physically short and easy to handle while having wide degrees to be easy to read. There is also a trap so that the column separates leaving liquid in the tiny bore to read instead of dropping quickly on removal. The liquid has to shaken out of the tiny bore back into the big one.
Is anthracene a sublimable substance?
Yes anthracene is a substance that can sublime.
Who invented laboratory thermometers?
There is debate on who invented the first laboratory thermometer especially since there different kinds invented at different times. However, many think the credit should go to Italian professor, doctor, and physiologist Sanctorius for the air thermometer in 1612.
Why does the substance in the thermometer go up when it gets hot?
The substance inside a thermometer expands when it gets hot due to increased kinetic energy of its molecules. This expansion causes the liquid to rise up the column, indicating a higher temperature reading.
Why does the mercury in the thermometer go up when the temperature is high?
In a mercury thermometer, the mercury expands when it is heated, causing it to rise in the thermometer's narrow tube. This increase in volume is a physical property of mercury known as thermal expansion. The height of the mercury column in the thermometer is then used to measure the temperature.
How does a glass thermometer works?
As the liquid in the thermometer is heated it expands, and the only way the expanding liquid can go is upward. As the liquid in the thermometer cools, it will contract, and the liquid will fall back down into the resevoir, causing the column of liquid to move downward.
When a substance is heated where does the energy go?
When a substance is heated, the energy is absorbed by the substance's particles, causing them to move faster and increase in temperature. This energy can be used to break intermolecular bonds and change the substance's phase, such as melting a solid into a liquid or boiling a liquid into a gas.
Why does the thermometer go down when cooled?
The cold reduces the temperature in the liquid inside the thermometer bulb. Most substances contract when their temperature drops so the liquid in the bulb occupies less space. this causes the column of liquid outside the bulb to become smaller.
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.
What makes mercury in a thermometer go up and down?
Change in temperature is what cause the Mercury to expand up (hotter) or shrink down (colder).

When you insert a column where does it automatically go?
The column will go where the currently selected column is, pushing all columns to the right. So if column D was selected and you inserted a column, column D would become column E and the inserted column would now be column D.The column will go where the currently selected column is, pushing all columns to the right.

Why are the numbers where they are on a thermometer?
The numbers are where they are because the person who made the thermometer scale decided which numbers go where.
Can a meat thermometer go in the oven for accurate temperature readings?
Yes, a meat thermometer can go in the oven for accurate temperature readings as long as it is an oven-safe thermometer designed for high heat cooking.
What do you put the thermometer on on poptropica?
When you get to the lighthouse, you go up the stairs with the torch and your player will say something. Go to your inventory and equip the thermometer and it will place it for you.
