What is a Beckmann differential thermometer?
A sensitive thermometer with an adjustable range so that small differences in temperature can be measured.
What would the air temperature inside a small building be if it is in the sun and the outside temperature is 100 degrees?
Probably the same, for the equilibrium would take place sooner or later.
What is the use of laboratory thermometer?
As well known, thermometer is an instrument used to measure temperature. Thermo is referred to heat and -Meter is referred to the measuring instrument. The laboratory thermometer is normally mercury based as it expands at a steady rate and has a higher density than water's. This allow it take a small height to expand compare to water which is 13.6x more than the height of mercury when it expands as their density are 13600kgm/s for mercury and 1000kgm/s for water. Furthermore, the mercury used is not poisonous and therefore is safe to be used by students at school. Laboratory thermometer is used to measure low temperature which is between -10 degree Celsius to 120 degree Celsius. This is because in school laboratory, the experiments we conduct just within a small range of temperature around the room temperature., which is about 27-29 degree Celsius.
Do candles increase room temperature?
yes but only if u eat cheese first... in fact even more so if you have wine with your cheese. Realistically though I have heard that a small candle can increase the temperature of your car by 10 degrees when stranded in the cold. By that rationale I am certain that a dozen candles increases the temperature of my small bedroom on a cool day. Efficient? Probably not...
What do you need in order to prove the law of conservation of mass?
You need a closed system where matter and energy cannot escape. Because gas moves through small openings, rubber stoppers should be put in place, if the reaction has a high output of energy, then electrical thermometers should be added. If light is emitted, a photosensor should be used.
What are the uses of the digital thermometers?
They're thermometers..... So.... They do the exact same things as normal thermometers, except the temperature comes out on a small, digital screen. -.-
In the Arctic region the daily temperature range?
the daily temperature range is very small and is always extremely cold
Why can't water thermometers register at 4 celsius?
Around 4°C, the curve of volume vs. temperature is horizontal, meaning that for small changes in temperature, the volume will NOT change.
What has the author Seppo Huovila written?
Seppo Huovila has written: 'Contribution to the measurement and interpretation of small-scale temperature fluctuations' -- subject(s): Thermometers and thermometry, Atmospheric temperature
Does thermometer measure heat or temperature?
Different thermometers make use of different physical properties, that change with temperature - for example, volume, electrical resistance, and others. The basic household thermometer simply has a liquid - previously mercury, nowadays usually colored alcohol - that expands when it is heated.
What is clinical thermometers?
A clinical thermometer, this type of thermometer is sensitive to very small changes in temperature but is able to measure temperatures only within a few degrees of normal body temperature (thirty seven degrees celsius).
What region of the world exhibits a small annual temperature range?
The tropical regions.
Why is mercury is preferred in ordinary thermometers?
To measure the temperature calibrated in the thermometer. Mercury as a liquid reacts well to temperature changes. It expands as it gets warmer, so thermometers measure the rise of the mercury to measure temperature.
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.
What kind of a device is a thermopile?
Thermopiles respond to changes in temperature and create electricity from this. They are made of thermocouples connected together in a small series depending on the device the thermopile is in. They are usually attached to devices like thermometers or professional devices used to measure a person's temperature.
What is a Beckmann differential thermometer?
A sensitive thermometer with an adjustable range so that small differences in temperature can be measured.
What materials are inside oven thermometers?
Wire and a small device called a 'thermistor'
