Why does a clinical thermometer has the range between 35 c to 42 c?
It's the expected range of human body temperatures, so extending its range outside these limits (1) gives more reading span than needed, and (2) makes it harder to get a quick and accurate reading.
What instrument gives the same reading each time it makes the same measurement?
A precise instrument. It is not necessarily accurate.
Why is a laboratory thermometer not used to measure the body temperature?
A thermometer used to measure body temperature is extremely accurate over an extremely small range of temperatures. It will give the temperature to the tenth of a degree. A laboratory thermometer does not have the partial degree separations but gives the temperature over a much wider range of temperatures.
What is the working principle of a liquid in glass thermometer?
Liquids expands on heating and contracts om cooling , when it expands it gives the reading
What's the difference between a thermometer and a temperature sensor?
A temperature probe incorporates a thermocouple in its tip which gives a signal to a piece of electronic kit which translates the signal into a temperature figure. A thermometer is a direct reading instrument which usually incorporates a bulb containing mercury or another fluid, or it may use a bimetallic strip which bends under temperature changes. A thermometer is good for ambient measurements but not suitable for putting into small spaces or pressure vessels for example. A probe is more versatile.
What is the best thermometer for taking temperatures?
rectal because gives most accurate reading
What do you call the thermometer that you stick in your ...?
It's called a rectal thermometer. It gives a slightly more accurate reading than when put under your tongue or in your armpit.
How do you find a temperature of a shirt?
The only possible way is to use a thermometer. The best kind is the instantaneous electronic thermometers where you point at an object and it gives you the temperature reading.
Why the reading of thermometer is taken when the mercury stop expanding?
The mercury will expand and rise up the thermometer tube until it reaches the temperature of the air around it. When it stops expanding, it is the same temperature as the air, and therefore gives an accurate reading.
A psychrometer gives the same reading on both thermometers. What is the relative humidity?
100 %
A bulb thermometer gives an indoor temperature reading of 21 degrees celsius A digital thermometer in the same room gives a reading of 20.7 degrees celsius Which device is more precise?
i got this for science homework too
A psychrometer gives the same reading on both thermometers what is the relative humidity?
100% because, let's say that both the thermometers have a reading of 66o degrees celcius. 66o is 100% of 66o, so the relative humidity is 100%.
How does a thermometer measure temeperature?
Mercury (the red liquid) is used in many older thermometers because it is the only metal which is liquid at room temperature and expands uniformly as the temperature increase. Thus, as the temperature rises and falls the mercury rises and falls inside of the thermometer and gives us a reading as to what temperature it is. Most electronic thermometers used are called thermo-resistors. These types of thermometers use semiconductors that act as temperature sensitive resistors. The colder it is, the less conductive the semiconductor is. A computer measures the conductivity of the metal and determines the temperature based on the resistance of the semiconductor.
Why does a clinical thermometer has the range between 35 c to 42 c?
It's the expected range of human body temperatures, so extending its range outside these limits (1) gives more reading span than needed, and (2) makes it harder to get a quick and accurate reading.
Thermometer is better than finger for assesing temperature in liquid why?
Because your finger doesn't give you a number for temperature. And also, if the liquid is quite warm, it can burn your finger obviously. The thermometer on the other hand is made to deal with extreme temperatures, unlike your finger. It gives a precise, almost accurate reading of the temperature.
What is the use of barometer in detail?
barometer is an instrument used to measure the pressure in the atmosphere and it also gives as an accurate reading.
What instrument gives the same reading each time it makes the same measurement?
A precise instrument. It is not necessarily accurate.
