a. Wind chimes and musical instruments
b. Electrical wires
c. Decorative articles and jewellery
d. Cooking utensils

Answer 1

Answer:

Explanation:.a. Wind chimes and musical instruments: malleable and sonorous

c. Decorative articles and jewellery: malleable

b. Electrical wires: ductile and good conductor of electricity

d. Cooking utensils: good conductor of heat

Explanation:

there are a particular characteristics which are present in a lot of metal that helps them in identifying their characteristics and using them.

They are used in in musical instrument because they are also known as that is they have the capability to produce sound. They are used in jewelry because they are malleable and they can be e casted into small sheet. They are good conductors of heat and electricity and also ductile that is they can be drawn into thin wires

Answer 2

Answer:

a. Wind chimes and musical instruments: Wind chimes are malleable and sonorous, musical instruments are ductile and sonorous

b.Electrical wires: Electrical wire are Ductile and conductors of electricity

Explanation: a. Wind chimes are beaten into sheets(Malleability) into design and are hanged, when wind blows them, they produce a ringing, melodious sound, this property is Sonority.

Musical instruments are drawn into thin wires(Ductility) (for example Guitar, Violin etc) and are played to produce a sound(Sonority).

b. Electrical wires are used to produce electricity everywhere.They are drawn into thin wires(Ductility) and allow electricity to pass through them(Conductors of electricity).
