Why does the mercury move up and down the scale as the temperature changes?
A mercury thermometer is designed so that most of the volume of mercury in it is contained in a bulb, and only a small fraction of the total available volume is in the stem on which the scale is located. Rising temperatures cause the volume of the mercury to expand, and, since in a properly designed thermometer the bulb is always full, the expansion in volume shows as a rise of the location of the top of the total volume of mercury into more of the volume of the stem. (The unfilled part of the volume of the stem is evacuated to prevent development of an opposing pressure from any gas that might otherwise be present.) Falling temperatures have the opposite effect.
What mineral makes up a thermometer?
the red part in a thermometer is mercury.
How can you measure a room height using a thermometer?
1) Place thermometer perpendicular to the floor and against the wall. 2) Make a mark on the wall at the top of the thermometer. 3) Shift thermometer up so bottom is at mark. 4) Repeat 2) and 3) until close to the ceiling. 5) Shift thermometer up until it touches ceiling and mark location of highest mark on thermometer to determine fraction of thermometer length for last segment. This would give the height of the room in units of "thermometers". This is not a standard unit of measurement, but it is a measurement. If you desire a more standard unit like centimeters, then measure the length of the thermometer and multiply by height of the room in "thermometers". However, you didn't say whether you had a ruler for measuring the thermometer. As as alternative, you could look up the length of the thermometer in the catalog from which it was purchased.
Why does the liquid level rise in a theremometer when the temperature is higher?
When the liquid is heated (by the environment), the particles in the liquid have more energy, and start moving around more, which causes the liquid to expand and take up more room. Conversely, in cold temperatures, the particles do not have as much energy, and do not move as much, so the liquid contracts.
How do you Change Celsius to Fahrenheit on a ear thermometer from Meijer?
For a Meijer K1-8120 from Bestmed. Turn on the thermometer... when display pops up, press the button again. The units should now be in Fahrenheit . Hope this helps.
Why is the stem of thermometer made up of glass?
To enable you to read the level the fluid has reached
Why does the substance in the column of the thermometer go up when it is heated?
The substance expands - and the tube (column) constrains it to go upwards.
How does thermometer liquid?
When temperature goes up the liquid expands. The liquid then takes up more space and you see this as a rise in scale on the thermometer. The same applies vise versa
Why does a thermometer rise up when its hot?
Usually when a thing gets hot, it expands. The liquid in the thermometer gets hot, and expands, so it takes up more room in the tube.
What makes mercury go up and down a thermometer?
the heat and temperature that causes it to rise and fall.
How does liquid thermometer work?
When temperature goes up the liquid expands. The liquid then takes up more space and you see this as a rise in scale on the thermometer. The same applies vise versa

Why a mercruy in a glass thermometer holes up a uniform stem?
because it is cheap and it does not expand on heating therfore it doesnt break
Why does alcohol in a thermometer rise?
Alcohol in a thermometer rises whenever the temperature of its surrounding increases. As the temperature increases, the heat causes the alcohol to expand ever so slightly, which shows up as an increase of height of the alcohol in the tube of the thermometer.
What is the boiling point of the thermometer?
The question to ask is: What is the boiling point of mercury (as mercury is the substance within a thermometer, unless of course you are referring to the material that makes up the thermometer itself).You can simply google that.But...it's 356.7° C
What do you call the thermometers with the red stuff in it?
Mercury is a silver-white to dim substance. In the event that your thermometer is loaded up with a red fluid, your thermometer contains red colored liquor or mineral spirits and not mercury.
What Happens when you heat up a thermometer with your hands?
If you hold a thermometer close to you it will start to heat up. Your body temperature will start affecting it and the heat reading on it should start to rise. Once you pull it away from you (depending on the temperate of where you are) it should start to cool off again.
