Well, honey, alcohol has a lower freezing point than water, so it won't freeze in cold temperatures. Plus, it has a wider temperature range for measurement. And let's be real, nobody wants a broken thermometer just because it got a little chilly outside.
Perhaps the most common use of eosin dye is in blood testing. Technicians mix the dye with a small amount of blood, then count how many cells absorb the fluorescent red dye. Several serious diseases cause a count of more than 500 eosinophils/microlitre of blood.
that depends on what type of thermometer. The tube thermometer, the kind with a glass tube with a red liquid in it, uses a small amount of mercury in a very small tube. When the mercury is heated, it expands, pushing further up the tube, as it cools it contracts, going down the tube. A dial thermometer also works on expansion and contraction, but with a coil instead of mercury.
this is how to make the easyest homemade thermometer projectwhat you need: bowl, water, food dye, bottle of drink like coca-cola bottle,play-doh and a straw.building step:step 1: add water into the bowlstep 2: add dye in the bowl of waterstep 3: put some play-doh on the bottle hole and make sure that you put your play-doh around the straw and around the bottle holestep 4: make sure that there is no air and water in the bottle and that the straw is not blockedstep 5: put your bottle part with the water part, but make sure that you don't put water in the bottle because the water will get upper when coldstep 6: put some ice on top of the bottle and wash your red liquid climb up with the ice on top of it.important note: this project do not work like a normal thermometer because normal thermometer have liquid going up when hot and this project go up when cold, please do not frost the dyed water, only frost the top of the project.i made this project at school and though to tell it to all of youWikiAnswers name: Gentlyjack12rd important note: if you edit my page please say what you want to say and put your WikiAnswers name.THANK YOUif you know how to make a thermometer, say your answer with responsibility and will agreed your answers
The rocks in the canyon have varying hues of red, and tan, and indigo. The indigo plant was widely use to make a blue clothing dye.
The red dye is added to make it easier to read the temperature scale on the thermometer. The dye provides a contrast against the clear liquid, making it more visible and accurate to read the temperature markings.
Alcohol, usually with a red dye in it
so that the person that is checking the temperature can see it clearly
The red liquid in a liquid-in-glass thermometer is mineral spirits or ethanol alcohol mixed with red dye. A grey or silver liquid inside the thermometer is mercury. Mercury thermometers are not used anymore due to the dangers associated with mercury.
If the red dye in a thermometer is separated, it likely means that the thermometer has been exposed to extreme temperatures or has been mishandled, causing the dye to separate from the liquid inside. This can affect the accuracy of the thermometer readings and may require replacing the thermometer.
The red liquid in a thermometer is typically mercury. Mercury is used because it expands and contracts uniformly with changes in temperature, allowing for accurate temperature readings. However, due to the toxicity of mercury, many modern thermometers use safer alternatives like alcohol or digital sensors.
The red appearance of the mercury in a thermometer is due to the use of red dye in the mercury to make it more visible against the clear glass tube. The dye helps in magnifying small changes in temperature by making the level of mercury easier to read.
The planet Mercury is grey, similar in colour and general appearance to our moon. Red Mercury is a chemical made of Iodine and Mercury. It was used as a medicine a long time ago before people realised it was actually poisonous. It is either in the form Mercury(I) iodide or Mercury(II) iodide.
Coke contains "caramel color," which is brown. It doesn't have red dye in it.
The Cochineal is an insect used to make carmine dye, a red tint. In various forms it is used to dye fabrics, cosmetics, paints, food coloring for cheeses, yogurts, alcohol, and baked goods. The dye is created from either drying and pulverizing the bodies of the insects, or boiling the dried bodies in which various compounds and elements are added to create the dye. This is not considered a Kosher food in Muslim and Jewish cultures.
most likely it is the red dye food coloring that is added to make it red
The red spirit in a thermometer is typically made of alcohol or a similar liquid that expands and contracts with temperature changes. This allows the thermometer to accurately measure and display the temperature. The red color makes it easier to see and read the temperature level.
