Calibration is the process of configuring an instrument to provide a result for a sample within an acceptable range, ensuring accuracy and precision in measurements. It involves comparing the measurements of a device under test with a standard or reference to detect, correlate, report, or eliminate by adjustment any variation in the accuracy of the instrument being calibrated.
Thermochromism is the property of substances to change color due to a change in temperature, which is often utilized in applications such as mood rings, thermometers, and smart windows. This phenomenon is primarily driven by molecular structural changes or phase transitions that alter the way a material absorbs and reflects light.
A bimetallic strip is a component made of two different metals bonded together that expand at different rates when heated, causing the strip to bend. This property is utilized in various applications such as thermostats and thermometers to convert temperature changes into mechanical displacement.
