Question

Two metal strips that constitute a thermostat must necessarily differ in their (A) Mass (B) Length (C) Resistivity (D) Coefficient of linear expansion

Tardigrade Admin · Accepted Answer

Thermostat is used in electric apparatus like refrigerator, iron etc., for automatic cut off. Therefore, for metallic strips to bend on heating their coefficient of linear expansion should be different.
