it rises because the molecules are expanding the space between each other and they have nowhere else to go but up. when it is cold the molecules move closer to each other therefore the liquid will appear to be moving downward.

Why does the liquid in the thermometer go up and down when the weather changes?
the liquid in the thermometer rises because of the surrounding heat which causes a chemical reaction wihtin the substance which makes the liquid rises. When, the liquid sinks, itn is because the air has gotten cooler
Thermometer is better than finger for assesing temperature in liquid why?
Because your finger doesn't give you a number for temperature. And also, if the liquid is quite warm, it can burn your finger obviously. The thermometer on the other hand is made to deal with extreme temperatures, unlike your finger. It gives a precise, almost accurate reading of the temperature.
Why is it necessary to warm the thermometer before placing it into the solutions?
The thermometer reading will change from reading the solution temperature.
Is peee warm or cold?
It is Warm because it has just can out of your bladder which is inside your body and the inside of your body is warm so yeah it is warm
What would the result be if a recovery cylinder were filled with liquid and allowed to warm up?
The result of filling a recovery cylinder with iquid refrigerant and allowing it to warm up is that the heat of the container would warm the refrigerant inside of it. The refrigerant would, as a result expand.
What happen to the liquid in a thermometer when it gets warm?
The liquid expand from heat. We use these expansion to indicate temperature. Common thermometer liquid is Mercury and alcohol.
What happens to the mercury in the thermometer when the air gets warm?
mercury explodes
What happens to liquid water when you add heat?

What are the advantages of a liquid in glass thermometer?
When the glass thermometer is in contact with a warmer object, conduction will cause the galss bulb to warm. This will cause the liquid inside the bulb to warm and, as a result, to expand. Since this liquid has nowhere else to go, it will expand into the capillary at the end of the bulb. The capillary is placed next to a graduate scale which is calibrated to give the temperature.
Which tool tells you how warm the water is inside the fish tank?
A thermometer. You can get them for a grrrreat price at www.bigalsonline.com
What do you do if your cellphone gets liquid in it?
Switch it off & remove the battery. Place it somewhere warm - such as on top of a warm (NOT hot !) radiator, with the battery cover removed, so that any liquid inside the phone should evaporate. Leave it at least eight hours (preferably overnight) and it should work.
How the inside of green house works?
sun warms it, it gets warm
Is it true condensation of water vapor occurs when air gets warm?
No, this is backwards. When air gets warm it can hold more water vapour so liquid water will evaporate.
What would happen if a person who is wering a hevy winter jacket were to place a thermometer inside the jacket next to his or herskin?
If you place a thermometer by a person skin in a winter jacket it would be warm because the jacket is keeping in the heat.
