usually an alcohol and different alcohols in each bulb that change relative densities at different temperatures.

The coefficient of thermal expansion for the liquid in the thermometer (mercury, alcohol, etc.) is greater than that for the glass capillary tube it is in.  Therefore, as the thermometer heats up, the liquid expands relative to the tube and is forced up the tube.  Conversely, when the thermometer is cooled, the liquid is drawn back down the tube.  The small bulb of liquid at the base of the thermometer magnifies this effect.

erm, high, like really hot. ok, the melting point of α-D-glucose: 146°C\nβ-D-glucose: 150°C [1]\nit probably decomposes before it boils but i found this phase change data [2]\n\nQuantity Value Units Method Reference Comment \nTfus 423.

At 20 degrees C, it's 0.6g/100mL. You can convert that to a Ksp.

This is a bit complicated but you might try this....\n\nStart with a centralized heat source, preferably electrical, so it should remain fairly constant.  You will need three thermometers, each to be held in place by their own stands.  Place a block or bar of metal so that it does not quite touch the heat source, and in contact with its thermometer at the far end.  Place a wooden bowl with water (a metal or glass container would taint your study ) near the heat source with its thermometer just in the water.  Place your last thermometer the same distance from the heat source, thus testing the heat conductivity of air.  If you had access to more thermometers and stands, you could place them at various points in a line from the heat source.  You will notice that the last thermometer will by far have the lowest readings.

Mercury freezing point: -38.72 degrees C\n\nA mercury thermometer will probably lose accuracy somewhat above the freezing point, because as one approaches the phase\ntransition from liquid to solid, one loses the linear dependence\nof the column length on temperature.\n\n\nAlcohol's freezing point is -117 degrees therefore it doesn't get cold enough to freeze alcohol.\n\nTherefore alcohol is better at low temperatures

Solid, there are only 2 elements that are liquid at room temperature, Mercury, and Bromine. 2 other elements will melt from the heat of your hand, (slightly above room temperature), Cesium and Gallium.

A mercury-in-glass thermometer, invented by German physicist Daniel Gabriel Fahrenheit, is a thermometer consisting of mercury in a glass tube. Calibrated marks on the tube allow the temperature to be read by the length of the mercury within the tube, which varies according to the temperature. To increase the sensitivity, there is usually a bulb of mercury at the end of the thermometer which contains most of the mercury; expansion and contraction of this volume of mercury is then amplified in the much narrower bore of the tube. The space above the mercury may be filled with nitrogen or it may be a vacuum.\n\nAs an alternative to mercury, some household thermometers contain alcohol with a red dye added. These are safer and easier to read.\n\n\n\nThermometer: A device used to measure the temperature of gaseous, liquid or solid matter or of a chemical reaction such as fire. Temperature measurement is important to a wide range of activities, including industry, scientific research, and health care. In health care, thermometers are used to measure the temperature of the human body. They include the following types: \n\nOral thermometers (those placed under the tongue) \nRectal thermometers (those placed within the rectum) \nMulti-purpose thermometers (those that can be placed under the tongue, in the rectum or under the armpit) \nEardrum thermometers (those placed inside the ear). \nBasal thermometers (highly sensitive thermometers placed under the tongue or in the rectum to measure slight temperature changes indicating that ovulation has taken place in a woman). \n\nPrinciples of operation of infrared thermometer:\nAll object surfaces emit infrared energy. The hotter an object is, the more active its molecules are, and the more infrared energy it emits. An infrared thermometer incorporates optics that collect the radiant infrared energy from the object and focus it onto a detector. The detector converts the energy into an electrical signal, which is amplified, digitally converted and linearized to be available as a linear electrical output signal from 4 to 20 mA. The temperature of the body can therefore be determined by measuring the intensity of this infrared energy.

In part, specific gravity can be measured with a hydrometer.  You establish a range that the liquid displaces and let it bob until it comes to equalibrium.  This test can be measured at any temperature.  \n\nHowever, mass density is done in a container that is kept at a constant temprature.  The math is easy once the measurments are taken, but there is more time involved in setting up the test and bringing the whole thing to equalibrum

um, no. It's not mercury. Liquids can mean any liquid, not just a periodic element. Lauric Acid has an atomic mass of 280g/mole, which is OVER any element by itself and it's melting point is at *negative*16 degrees Celsius. Long fatty chains like vegetable oils are in multiples of that.

the easy answer is that it is less dense, but if you want the real answer, it is most dense at 4C, here is a graph\n\nhttp://www.piercecollege.edu/offices/weather/water.html

The test liquid will sink to the bottom because it is more dense than water. Water has a density of 1.0 g/ml. There fore it can be simply thought of as "lighter."\n\nThere will be two visible separate layers.

There are several way in which a barometer work.  The most common is a needle attached to a spring and a tensioning device which expands and contracts based upon the amount of atmospheric pressure it is exposed to.  \nThe second type is what is called Galileo's barometer.  Globes are filled with a number of\nliquids of different specific gravities (this is the density of the liquid with respect to the density of water).  As the air pressure changes, these different globes will either float or sink based upon the changes in air pressure.   The third type is the electronic barometer.  It uses a pressure transducer, which causes changes in electric current bases upon changes in air pressure.  These changes are converted into either an analog (needle meter) or digital display of the value of the air pressure.

"A heat pack like the one you are describing contains sodium acetate and water. It turns out that sodium acetate is very good at supercooling. It "freezes" at 130 degrees F (54 degrees C), but it is happy to exist as a liquid at a much lower temperature and is extremely stable. Clicking the disk, however, has the ability to force a few molecules to flip to the solid state, and the rest of the liquid then rushes to solidify as well. The temperature of the solidifying liquid jumps up to 130 degrees F in the process.\n\nWhen you boil the solid, you melt it back to the liquid state. You have to completely melt every crystal, by the way, or the liquid will quickly re-solidify. You can repeat this cycle forever, theoretically, just as you can freeze and melt water as many times as you like. The plastic pouch eventually wears out and leaks, though (since sodium acetate is a food additive, it is non-toxic)."
