What is the temperature coefficient?
The material temperature coefficient describes how a certain property changes when the temperature increases or decreases by 1 Kelvin (equivalent to 1 ° Celsius). Some of the common properties that differ in temperature include electrical resistance and elasticity. Linear changes in material properties are easy to calculate the temperature coefficient, but the calculations are more difficult if the change in the properties is not linear. There are a number of practical applications for materials that change with temperature, especially in electronics, and therefore the study of temperature coefficients is important.
When a substance is heated or cooled, its properties can change. For example, the resistance of the object may increase or decrease depending on its temperature. Other properties such as the elasticity of the material may also vary depending on the temperature. Substances with temperature -related properties are useful for different different application, so scientists must be able to accurately assess what changes will occur with a particular type of material. In other words, tThe eplot coefficient is how the property changes when the temperature changes 1 Kelvin. The Kelvin scale is an alternative temperature rate with a point other than the Celsius scale, but a change in 1 Kelvin is the equivalent of 1 ° Celsius.
As the material changes with the temperature, it depends on different factors. For example, some materials have an electricity resistance that changes linearly with temperature. This means that if the temperature doubles, then the resistance will also double. It is much easier to calculate the temperature coefficient if the material varies linearly with the temperature.
If the change with the temperature is not linear, it is more difficult to calculate the temperature coefficient. In this situation, scientists usually try to discover a number of temperature coefficients that can be used in different temperature ranges. However, it is not always possible to calculate the useful temperature coefficient.
An example of a practical application that is possible because of the known temperature coefMaterial Icient is temperature -dependent resistors. They are used in a number of electrical circuits and allow the engineer to change the way the circuit behaves depending on the outside temperature. Without being able to predict how the material reacts to temperature changes, it would not be possible.
