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.
The red stuff in most thermometers is alcohol. The silver stuff is Mercury.
The red liquid inside thermometers is usually colored alcohol or a similar fluid, like dyed ethanol or kerosene. These liquids are chosen for their low freezing points, wide temperature range, and visibility against the white thermometer background.
Because we do!
1. It is the only metal that is a liquid at room temperature. 2. It's is hightly toxic. 3. It's used in the thermometers with the red liquidy stuff.
it is made up of mercury the stuff that used to be in thermometers
Some thermometers use mercury, in these the liquid is silvery. Some thermometers use a red dyed alcohol solutioin.
Digital thermometers, infrared thermometers, and alcohol or galinstan thermometers are commonly used as alternatives to mercury thermometers due to the environmental and health risks associated with mercury.
Mercury is traditionally used in thermometers to measure temperature due to its high thermal expansion and conductivity properties. However, due to its toxic nature, many countries have shifted to safer alternatives such as alcohol or digital thermometers.
The red liquid in a thermometer is called mercury. Mercury is a metal element that expands and rises in the thermometer when exposed to heat, allowing for temperature measurement. However, due to its toxicity, mercury thermometers are being phased out in favor of safer alternatives.
The red stuff is actually miconium- a stored waste product of the larvae (caterpillar).
There are 34 different types of thermometer that range from alcohol thermometers and ear thermometers to medical thermometers and electrical resistance thermometers.
If exposed to extreme heat yes the mercury will expand until the glass tube explodes
