Why should not use water in the thermometer?
One of the problems with water in a thermometer is the effect of capillary action - the column of water tends to "stick" to the sides of the thermometer and create a U-shaped surface at the top. This makes it very difficult to read the thermometer. Previously mercury was considered to be a good medium for thermometers, but this has been discontinued due to the health risks from a broken mercury thermometer; the current medium in thermometers is dyed ethanol or methanol.
Are alcohol thermometers better than mercury thermometers?
Both alcohol and mercury thermometers are effective for measuring temperature, but alcohol thermometers are generally safer to use due to the toxicity of mercury. However, mercury thermometers provide more accurate readings at higher temperatures compared to alcohol thermometers.
What property of half-lives makes radioactive material so problematic?
The property of half-lives that makes radioactive material problematic is that they can remain dangerous for long periods of time. This means that even after a substantial amount of time has passed, the material can still emit radiation and pose a threat to human health and the environment.
Why mercury is preferred as a thermometric substance?
Reason1.The mercury is good conductor of heat and expand rapidly and thus the temp;change quickly. 2.Mercury has a low heat capacity3.The mercury is opeque to light and can been seen clearly4.The mercury does not stick with the wall of container.5.Mercury has a freezing point of -39c and boiling point of 357
Is mercury explosive?
No, bit it can be used as a switch in a detonator for explosives. It is liquid and conductive and so movement makes the makes the material flow and bridge contacts completing a circuit and causing detonation.
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
Why isn't mercury in thermometers any more?
I don't know to what extent mercury is still being used, but it makes sense to phase it out: mercury is extremely toxic. If a mercury thermometer breaks, you have to be careful not to breathe the vapors.I don't know to what extent mercury is still being used, but it makes sense to phase it out: mercury is extremely toxic.

What makes mercury special that it can be used in a thermometer?
Mercury is a heavy metal also known as QUICKSILVER it is special because it is in a form of liquid
What makes mercury go up and down a thermometer?
the heat and temperature that causes it to rise and fall.
What makes mercury in a thermometer go up and down?
Change in temperature is what cause the Mercury to expand up (hotter) or shrink down (colder).
What makes mercury so special it can be used in a thermometer?
Mercury is a heavy metal also known as QUICKSILVER it is special because it is in a form of liquid
Why is mercury used in a thermometer why not green water?
Water does not change as much in volume with temperature as much as Mercury does, which makes it more difficult to read temperature Changes on a scale.
Explain how a deformation thermometer measures temperature?
IT measures it by the alcohol or mercury being touch by heat so the fluid rises.There is a chemical in the thermometer (the red liquid ) and it reacts to heat or coldness. cold makes it retract and the heat makes it expand * * * * * That is NOT a deformation thermometer but an expansion thermometer. A deformation thermometer has a bimetallic strip. This is a strip made by joining together two strips of metal with very different coefficients of thermal expansion. When heated, one of the metals expands much more than the other. But, because they are bonded together it is not permitted to expand freely and as a result the bimetallic strip is deformed. The amount of deformation is converted to a temperature scale for display.
Why do we jerk a clinical thermometer?
We jerk a clinical thermometer to ensure that the mercury or alcohol inside is at the lowest point on the scale before use. This makes sure that we get an accurate measurement of body temperature when placed in the mouth, under the arm, or in the rectum. Jerking the thermometer helps to reset the mercury column to the starting position for a new reading.
What is mercury's mass made of?
It is made up of the material which makes up the planet.
Which property makes it difficult for electricity to pass through a material?
density
What property of glass makes it a good material for windows?
you use salt
