Final answer:
The resistance of an object can be affected by changes in temperature. Thermistors, which are semiconductor crystals with a strong temperature dependence, are commonly used for temperature measurement.
Step-by-step explanation:
The resistance of an object can be affected by changes in temperature.
This relationship is described by the equation R = Ro (1 + αAT), where Ro is the original resistance and R is the resistance after a temperature change AT.
Thermistors, which are semiconductor crystals with a strong temperature dependence, are commonly used to measure temperature based on the effect of temperature on resistance.
