Quick Summary

A thermometer is an instrument used to measure temperature. The concept of temperature is fundamental to thermodynamics and is a measure of the average kinetic energy of particles within an object.12

A bimetallic strip is a thermometer component made of two different metals bonded together. When heated, these metals expand at different rates, causing the strip to bend. This bending action is used to indicate temperature changes. Historically, bimetallic strips were used in thermostats as temperature sensors, though modern devices often use thermistors.31
