Vedclass · Answer

$(A)$ Bimetallic strip works on the principle of thermal expansion of solids, where two different metals expand by different amounts when heated, causing the strip to bend. Thus, $A \rightarrow (s)$.$(B)$ $A$ steam engine converts thermal energy (from steam) into mechanical work. Thus, $B \rightarrow (q)$.$(C)$ An incandescent lamp works by heating a filament to a high temperature, causing it to emit light via radiation. Thus, $C \rightarrow (p)$.$(D)$ An electric fuse is a safety device that melts when the current exceeds a specific limit, breaking the circuit. Thus, $D \rightarrow (r)$.Therefore, the correct matching is $A \rightarrow (s), B \rightarrow (q), C \rightarrow (p), D \rightarrow (r)$.
