Question

Scientific Reason in the electric equipment producing heat e.g .iron, electric heater, boiler and toaster an alloy such as nichrome is used, not pure metals

Answer 1

Answer:

nichrome is the alloy of nikel and chromium which has high resistivity and high melting point. In this high resistivity is used to produce heat which make it red hot and high melting point help it stop the alloy from being melt. But

pure metals may have low resistivity or low melting point. So nichrome is used in heat applying products like toaster, hair dryer, iron etc.
