(A)→(S) We know that bimetallic strip works on the fact that solids expand on heating. (B)→(Q) Thermal energy is converted into mechanical energy in steam engine. (C)→(P) In an incandescent lamp, due to conversion of energy, the lamp becomes hot. The hot body radiates energy by virtue of temperature. (D)→(R) In an electric fuse, electrical energy is converted into heat energy. If the current exceeds its permissible value, the fuse gets melted down because of the excessive heating.
