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.

How is the pH scale different from other scales of measurement like the Fahrenheit temperature scale?
pH is a logarithmic scale, so a change of 1 in pH means a change of 10 in the quantity. It is also negative, so as pH increases the measured quantity actuallly goes down. The temperature scales are simply direct scales; all changes mean the same thing and going up means going up.
How do you change the digital temperature to Fahrenheit in a 2006 tiburon?
Hold the OUTSIDE TEMP and down on the TEMP button till it changes
What is the word equation for solid mercury two oxide breads down when heated forming the elements mercury and oxygen?
Mercury+Oxygen----> Mercury Oxide
What is the opposite of Celsius?
It is an international metric temperature scale on which water freezes at 0° and boils at 100° under normal atmospheric conditions. The term "Celsius" is usually preferred to "centigrade," especially in technical contexts. Until 1948 the scale was known as centigrade when it was renamed in honour of Celsius, though in general usage (for example television weather forecasts) it was still called centigrade until quite recently. Celsius refers to Anders Celsius, the Swedish Astronomer who developed the temperature scale with 100 degrees at the freezing point of pure water (actually its triple point) at normal pressure and 0 degrees at its boiling point. On his death in 1744 Linneaus reversed the scale.
How does living near ocean affect climate?
Land hearts up & cools down quickly compared to water. It is rapidly by changes in the amount of sunlight & the air temperature
Why does the mercury moves up and down the scale as the temperature changes?
because it goes up and it goes down which creates the oxide to create a firm to make the thermionic to keep the track
Is there a new substance formed when mercury and iodine are ground together?
When Mercury and Iodine are ground together, a compound called Mercury(I) Iodide is formed with the chemical formula Hg2I2 but this compound is sensitive to light and will break down into elemental Mercury and Mercury(II) Iodide with the chemical formula HgI2 .Interestingly, Mercury(II) Iodide changes color with changes in temperature, changing from orange at room temperature to yellow above 126 degrees Celsius due to a change in crystal structure.
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 are examples of thermal expansion and contraction?
the Mercury in a thermometer expands when heated and contracts when the temperature cools down.
Why do you use mercury in thermometer?
As tempertature rises, the mercury in the thermometer expands, causing it to go up. As temperature decreases, the mercury in the thermometer contracts, causing it to go down on the scale. However, mercury thermometers are very dangerous if it breakes and gets on your skin. so it it reccomended to use an electric thermometer. these thermometers use thermoelectric current to measure temperature. ergo. they are safe if they break cheers <3 -Eli

How is the maximum temperature recorded?
In the days when only mercury thermometers were available a small indicating pellet was placed on top of the mercury thread inside the thermometer. As the temperature rose he indicator was pushed up against a calibrated scale with the mercury. When the maximum temperature had been reached and the thread of mercury fell the indicator remained at the highest point until read and reset by shaking down the tube. Today digital thermometers have memories which can be interrogated electronically.
How do changes in temperature cause rocks to break down?
It breaks down the rocks
Is Mercury ductile?
Mercury is a liquid at room temperature. Ductile means that something is easily shaped or bent. No Mercury is not ductile. (at least not at RT)
What is the diffrerence between digital thermometer and mercury thermometer?
Digital thremometer is shows digit and run by electric or cells mercury thermometer is shows mercury up and down. when temperature low and down.
How does a thermomether works?
A mercury thermometer (like the kind a medic might use) is a thin glass tube filled with the metallic element mercury, which is a liquid. The rate at which mercury expands with heat is known and happens at a constant rate, so the movement of the mercury column up and down the tube can be read off at a scale on the side. Because mercury is relatively dense, it isn't affected too much by changes in atmospheric pressure.
