please answer this question
Answers
(a) Lustre
➡ Metal (Iron nail/Coin): Yes it shines.
➡ Non-metal (Sulphur): No, it is dull in nature.
(b) Hardness
➡ Metal (Iron nail/Coin): It is quite hard and does not break when force is applied.
➡ Non-metal (Sulphur): It is brittle in nature and crushes to form a powder when force is applied.
(c) Malleability
➡ Metal (Iron nail/Coin): Yes it can be drawn into thin sheets. A coin itself proves it as it is relatively in a compressed form.
➡ Non-metal (Sulphur): Sulphur cubes form a powder when tried to be beaten into thin sheets.
(d) Ductility
➡ Metal (Iron nail/Coin): Yes, it can be drawn into wires. A nail has a protruding end which displays this property.
➡ Non-metal (Sulphur): Sulphur cubes form a powder when tried to be drawn into wires.
(e) Conduction of electricity
➡ Metal (Iron nail/Coin): Metals are usually good conductors of electricity. Iron wires are used in electricity experiments in labs.
➡ Non-metal (Sulphur): Sulphur does not conduct electricity. When connected to a circuit, the bulb doesn't glow if sulphur is attached.
(f) Conduction of heat
➡ Metal (Iron nail/Coin): Iron conducts heat. It is used to make kitchen appliances and utensils.
➡ Non-metal (Sulphur): When heat is passed through sulphur, it undergoes a chemical change and a new substance is formed. It cannot conduct electricity.
