VARIATIONS IN PROPERTIES OF MATERIALS WITH TEMPERATURE

Variation of some property of a substance with temperature is utilized in most forms of temperature measurement.

Here, today, we will discuss about some of the properties which alter in various substances with temperature.

    1. You would have come across many substances which expand as their temperature rises. So, it can be said that a measure of temperature is obtainable if we are able to take equal amounts of expansion to indicate equal increments of temperature.

    2. As we would have seen in some liquids that when they are subjected to a temperature rise, their molecules gain some motion and there is a change of state from liquid to vapor. Therefore, we can say that equal increments of temperature can be indicated by measuring equal increments of the pressure of the vapor.


From the above various methods we can classify temperature-measuring instruments in the following ways:

  1. Expansion type (liquid or solid)

  2. Vapor-pressure type

  3. Electrical type: includes resistance and thermoelectric types.

  4. Radiation type
