Answer:
1.)APPEARANCE---Metals generally appear with grey or black coloured whereas non metals comes with multi colors.
2.)HARDNESS--- Metals are generally hard but non metals weak.
3.)MALLEABILITY--- Metals are malleable and can be splited into thin sheets while non metals can not.
4.)DUCTILITY--- Metals can be drawn into thin wires while non metals can not.
5.)HEAT AND ELECTRICAL CONDUCTION---Metals are the best conductor of heat and electricity whereas non metals are not.
GIVE REASONS----
A.)Aluminium is malleable, soft and does not react with food items, so it is used to wrap food items.
B.)Immersion rods for heating liquids are made up of metallic substances because metals are good conductors of heat and electricity. The immersion rod needs electric supply to get heated and; in turn; to heat liquids.
