What instrument measures relative humidity using two thermometers?
hygrometer psychrometer
Formula to work out humidity?
Relative Humidity can be measured with a psychrometer. A psychrometer has two thermometers, a wet-bulb and dry-bulb. The wet-bulb has a wet cloth on one end. If the wet-bulb is colder than the dry-bulb, than you apply the information to a psychrometer chart, which tells you the relative humidity, from which you can determine "high" or "low". http://andrewslog.files.wordpress.com/2008/04/48d16354-752c-4965-9c43-024073c31186.jpg
How would a thermometer has measure temperatures using the kelvin scale differ from one that measure temperatures using the celsius scale?
The degrees are the same size on both thermometers. But when the two thermometers are side by side and at the same temperature, the number of the reading on the Celsius thermometer is 273.15 higher than the number of the reading on the Kelvin thermometer.
What are alternatives to thermometers?
There are no convenient alternatives to using a thermometer to measure body temperature.
How do they measure temperature?
Using different types of thermometers, thermocouples, thermal resistances, pyrometers, etc.

How do you measure cooled temperature?
Cooled temperatures are still temperatures!. You can measure them using expansion thermometers down to around -15 deg Celsius. Below that you will probably need a thermocouple.

How does a labrotory thermometer work?
There are several types of thermometers in use in laboratories.The simplest is the liquid filled thermometer which converts the expansion of a liquid (mercury or alcohol) into a temperature reading.Bimetallic thermometers use the differential expansion of metals at given temperatures to indicate atemperature.Thermocouple thermometers use the current generated by dissimiiar metals at a temperature to provide a input to an appropriately scaled electrical meter.Liquid crystal thermometers rely on the different melting points of solids to show temperature.Temperatures of objects may also be determined by measuring the infrared emissions from its surfaceAlthough not in use in labs there are also interesting thermometers using the density of liquids at different temperatures to allow calibrated floats to rise or sinkTHANX
What are the disadvantages of using thermometers that do not contain mercury?
They are edible
How do you find low temperature extremes?
by using thermometers
Is Mercury used in thermometers?
In normal and some medical thermometers Mercury is used. That is why you may want to consider using electric thermometers which are more commonly used. They use no mercury.
Do you add one degree when using forehead scanner thermometers?
no
What are alternatives to thermometers?

What could you measure using of therma meter?
Thermometers are used to measure temperature.
