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.

The liquid in a thermometer move up the glass tube when the air temperature?
The liquid in a thermometer rises in the glass tube when the air temperature increases due to thermal expansion. As the temperature rises, the liquid (usually mercury or alcohol) absorbs heat and expands, occupying more space and causing it to move upward in the tube. This movement allows the thermometer to accurately reflect the ambient temperature. Conversely, when the temperature drops, the liquid contracts and moves down the tube.
Why lab thermometer do not have kink?
the temparature of the liquid must be read while the thermometer is in the liquid.since the level of mercury drops as soon as the thermometer is taken out of the liquid ,therefore no need of the kink in thermometer.
How does the alchohol thermometer works?
An alcohol thermometer operates based on the principle that alcohol expands when heated and contracts when cooled. The liquid alcohol inside the thermometer expands up the tube as the temperature rises and contracts as the temperature drops, allowing for temperature measurement based on the level of the liquid in the tube.
Why does the liquid mercury in thermometer fall on cooling?
When a thermometer cools, the temperature of the liquid mercury inside it decreases. As the temperature drops, the kinetic energy of the mercury atoms decreases, causing them to move closer together and occupy less volume. This contraction leads to the mercury descending in the narrow tube of the thermometer, reflecting the drop in temperature. Thus, the level of mercury falls as it cools.
Why the doctor drops the thermometer in a antiseptic solution?
Because it has just been in your mouth, which has many types of bacteria inside. This could harm someone else if it gets into them.
Rain is drops of liquid what?

How do I use hcg liquid drops?
You should have gotten instructions with it. However you typically will put some of the drops in your food before you eat it so it can absorb into your body to help flush the fat out.
What is the lowest temperature that a thermometer can go to?
The lowest temperature that a standard mercury or alcohol thermometer can typically measure is around -39°C to -40°C. Below this temperature, the liquid inside the thermometer may freeze, rendering it ineffective for measuring further drops in temperature. Digital thermometers may have a lower limit depending on their design and the type of sensor they use.
How long do you use the HCG liquid diet drops?
The drops need to be included with your food so it can absorb. So you have to take it before you eat. It needs to be taken continually for you to keep getting the effects of it.
