👉 In physics, a psychrometric device is used to determine the temperature of an object or substance based on its perceived change in color or texture. The term "psychrometry" refers to this process because it involves measuring and interpreting the way colors and textures change with changes in temperature. Psychrometrical devices are often found in thermometers, which measure the temperature of a substance through changes in its color or density. For example, a thermometer may be used to measure the temperature of a cup
