What are the uses and parts of a thermometer??

There is more than one type of thermometer.  The old ones are being traded for electronic ones these days because they have a mercury inside, which is very, very bad if it gets outside (breaks).  The old ones also have slender glass body sealed on one end by the glass and on the other with a metal tip that goes in your mouth (or rectum) and transfers heat to the mercury which rises up the glass tube, marked approrprietly to show the tempreture's the risig mercury represents.

In a mercury thermometer it is. Most common household thermometers will have a red or blue or some color other than silver inside, and these use a variety of other substances. Mercury thermometers will appear silvery in the center.

Since it measures air pressure it can be used for detecting changes in the weather as high and low pressure zones move across the planet. Another use for barometers is to measure changes in altitude. Most inexpensive altimeters are a barometer that is used to measure relative changes in air pressure in terms of change of altitude. (Radar and GPS altimeters do not work this way)

Take a pile of it, stick a thermometer in it, apply heat, and watch the temperature rise. When it changes from solid to liquid, bingo.

1-thermostat: It senses water temperature and deflects if the water is hot enough, causing a way open for water to circulate around engine cool the engine down.\n\n2- A sensor for battery resource which say to generator when to charge the battery.\n\n3- A sensor for oil level, you should get out of car \nand bring it out from oil tank and watch it, (oil gauge)\n\n4- Oil pressure sensor: alarms if oil pressure is dropped.\n\n5- Back gear light: turns the back gear lamp on if sense the gear is for back.\n\n6- Door opening: alarms if a door is open.\n\n7- Air bag: a mechanical sensor for impact.\n\n8- Gas tank: senses the amount of gas in the tank and say\n it.\n\n9- speed: a digital or mechanical sensor which can say the\n Amount of speed.\n\n10- Rpm: a digital or mechanical sensor which can say how fast is engine turning.

Actually, you can use many other materials for a thermometer, not just mercury.   Mercury is nice because it has properties that make it easier to build a more practical thermometer than the others.   For one it is liquid at room temperature.    Mercury would not be a good material for a thermometer below it's freezing point (see www.webelements.com for details)    Assuming we want thermometer for measuring temperature variations around room temperature, then the other properties of mercury, that is, its temperature expansion coefficient and pressure compressibility, are just right so it will expand predictably over the approximately 1 or 2 inch range that it in your thermometer.    \n\nHope that wasn't too long winded.

Think of different ways you could measure it and describe those methods.  Check the reference section of a library for the CRC Handbook for the specific heat of known reference materials.  Does the specific heat change with temperature?  How could you test that?  Think about measurement methods you could do, without fancy or expensive equipment.  Think about how you could test how good your equipment is and how you can get the best accuracy from it.  If you actually do it, you can make a good science project of it.

Measure a suitable mass of liquid in say a Styrofoam cup (let's say 100 g). Place thermometer in cup along with heating coil. Be sure that resistance heater does not touch the sides of cup or the thermometer. Have ammeter in series with the resistance heater and voltmeter in parallel. Turn on heater and note the current, voltage and time to reach say 10 deg C above the starting temperature. Electrical energy in = heat energy gained by the system. Electrical energy = current x voltage x time (in seconds). Heat gained = specific heat of liquid x change in temperature x mass of liquid.

disadvantage is that mercury is very toxic. so if the thermometer breaks it is very dangerous. one of the reasons it is still used is because it can measure very high temperature. \nMercury will solidify (freeze) at -38.83 °C (-37.89 °F) and so may only be used at higher temperatures

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.

1)Remember that a calories is a measure of the heat it takes \n  to raise 1 degree of the water temperature.\n2)A Calorimeter helps you measure among other thing the\nheat of fusion and since we know the heat of fusion of water its easier to calculate the heat of fusion of other things.

"Temperature" is the measure of the average kinetic energy of the particles of a substance.\nIn the case of using a thermometer to measure temperature, the temperature of the thermometer is what is actually being seen in the measurement, we just assume that it has come to thermal equailibrium (no net flow of heat energy) with the surroundings.\n\nSince a vacuum is totally empty (i.e. no particles), a vacuum does not have a temperature by definition.\n\nIf we also assume this vacuum system is isolated from the rest of the universe and that the walls are perfect reflectors, then the temperature reading on the thermometer will not change when placed into a vacuum....but remember the conditions which we just had to apply.\nThere are 3 methods in which heat [energy] is transfered, through conduction, convection, and radiation.  In a vacuum, conduction and convection are inappliacble in terms of carrying heat away from the thermometer (or to the thermometer).  However, radiation is still quite possible, and likely.  The thermometer will emmit Infra red radiation in the form of photons of light which will carry away heat energy from the thermometer (lowering its temperature).  Likewise, if we allow any other EM radiation to some into the box, it may increase the heat energy of the thermometer (and raise its temperature).  If we assume the box is isolated and its walls are perfect reflectors (which will refrlect 100% of any EM radiation the thermometer emmits back), then the thermometer's heat energy should remain constant as will its temperature.

they are convenient or traditional means of measuring the heat in a standard way to a specific act, for celcius, it conveniently measures temperature relative to the freezing and boiling point of water at 0, and a 100 degrees.  there are the absolute scales, but they dont give us a convenient way to measure things relative ot each other in general... on earth.  the temperature in space would typically be measured on the absolute scale (degrees rankine) that measures the heat of something relative to the absence of heat, where scientists suspect that all molecular motion stops.
