it is the uniform expansion of the liquid (Mercury) to temperature which give the reading.
im just doing this for revision for physics and the mark scheme for a past paper exam question asking exactly this was:
'idea of equal size divisions/expansion for equal temperature rises
OR ∆l / ∆θ constant OR reference to l against θ graph straight line
ignore 1 division = 1°C '
what this means is the liquid expands in proportion to how much it is heated. for example if the temperature is increased by two units then the liquid should rise for example by 3cm and when the temperature is increased by 4 units the liquid should rise by double so 6cm because the temperature has been doubled
hope this answers your question x
Linearity is a feature that ensure linearity. This is a thermometer.
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.
A thermometer is an instrument that measures cold and heat, together with temperature variations.

this is a thermometer that can work twice as much as a normal thermometer or a thermometer that can check the temperature of two things at the same time
yes ! to insure linearity
Within the thermometer's range of operation, a given temperature difference will result in the same expansion in the column of the thermometric liquid.
This would keep the voltage across the inductance a constant, and corrects the non-linearity problem.
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.
its important for recover the calculation equation and for improve linearity equation (pears low )
It is not possible to measure the room temperature with a thermometer. A digital oral thermometer will not work to measure the room temperature. It is meant to measure human temperature, not room temperature. You will need a room thermometer to measure the room temperature.
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.
When a function or given data set differes from a liniar curve fit. the difference between the data and a linear curve fit is your linearity error

yes
When a thermometer reaches thermal equilibrium, the temperature of the thermometer and the substance it is measuring are the same. Therefore, the thermometer is essentially measuring its own temperature.
