Answer 1

1 Copper is a good conductor of electricity & coppes wire transmit energy faster without causing wire neat - up. copper are resistant agaiust metal exhaustion. Copper required dess susulation & cau transfer high power call getting overloaded where as irou are less resistant against metal exhaustion. Iron wires are effective in handling low voltages, they are less pliable & durable . compared to copper wires. 2. Iron react with onygen present in cooker of moisturel ļ form ison oxide. This iron oxide (res03) is known as rust or corrosion. Iron onide is brown stor colour layer on the surface of Iron metal. - 4fe + 30₂ - 2Fe2O3 - Ferrous oxide (Rust) 13. Chlorine present in table salt react ealth aluminiu & form aluminium Chloride. The layer of aluminium chloride is develop on the surface of aluminum pots. Al + 3Nalls NO + Alche aluminium chloride
