Question

Quizplus · Accepted Answer

Bimetallic strip consists of two different types of metals having different coefficients of thermal expansion. When heated or cooled, the strip bends due to the differential expansion or contraction of the two metals. This bending can be calibrated to indicate temperature changes, making it usable as a thermometer.
