They work like a temperature gage.

Thermistors are devices which have large changes in resistance with respect to changes in temperature. This change in resistance can be either positive or negative, depending on the design of the thermistor. They are usually used to measure temperature , and can be quite accurate.

A themistor is a special kind of resistor.
We normally want a resistor's resistance to be stable despite changes in temperature.
The opposite is true of thermistors. They are manufactured so that their resistance changes with temperature.
This change can be an increase in resistance with an increase in temperature - a positive temperature coefficient, or a decrease in resistance with an increase in temperature - a negative temperatrure coefficient.

usally buy the coductance change. some conductors become very poor at higher tempratures.

due to heat, potential difference develops at oppostie side of material and due to developed potential differene it act as resistor
