Why does a mercury-in-glass laboratory thermometer have a narrow capillary bore?
To increase the sensitivity of the thermometer, that is, for the thermometer to respond quickly to small changes in temperature.
How do you increase the range of a thermometer?
If you're the one designing the thermometer, you could make it longer or make the bore wider. If you've got an existing thermometer, there's not much you can do.
What is meant by linearity of thermometer?
it is the uniform expansion of the liquid (mercury) to temperature which give the reading.
Why does alcohol in a thermometer rise?
Alcohol in a thermometer rises whenever the temperature of its surrounding increases. As the temperature increases, the heat causes the alcohol to expand ever so slightly, which shows up as an increase of height of the alcohol in the tube of the thermometer.
How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
The capillary tubing has a uniform bore in a mercury thermometer?
yes ! to insure linearity
What is linearity of a thermometer?
Within the thermometer's range of operation, a given temperature difference will result in the same expansion in the column of the thermometric liquid.
How does the temperature increase on a thermometer?
it gets hotter
Why does a mercury-in-glass laboratory thermometer have a narrow capillary bore?
To increase the sensitivity of the thermometer, that is, for the thermometer to respond quickly to small changes in temperature.
What is the need for trapezoidal waveform for linearity correction?
This would keep the voltage across the inductance a constant, and corrects the non-linearity problem.
How do you increase the range of a thermometer?
If you're the one designing the thermometer, you could make it longer or make the bore wider. If you've got an existing thermometer, there's not much you can do.
What is the limit of linearity range?
Limit of Linearity is the concentration at which the calibration curve departs from linearity by a specified amount. A deviation of approximately 5% is usually considered the upper limit. Common at higher concentrations.
What happens if you place a thermometer in any wavelength of visible spectrum?
Depending on the intensity of the light the thermometer should indicate an increase in temperature.
Linearity is how much important in method validation?
its important for recover the calculation equation and for improve linearity equation (pears low )
What happens to the values as you move up the left side a min thermometer?
They Increase.
What is terminal linearity?
Terminal linearity is when there is no flexibility allowed in the placement of the straight line in order to minimize the deviations ( or non-linearities). The straight line must be located so that each of its end points coincides with the device's upper and lower range values. This means that the non linearity measured will be larger than that measured by the independent linearity definitions.
What is meant by linearity of thermometer?
it is the uniform expansion of the liquid (mercury) to temperature which give the reading.
