Question

Electrical appliances, automobiles, satellites, aeroplanes.cooking utensils are made by metals due
to their
1) Sonarity
2) Ductility
3) Malleability 4) Both 2 and 3​

Answer 1

Hi there

correct answer is 4 both 2 and 3 because ductility and malleability property of metal is only useful in given appliances

Sonority is the ability to produce a sound when struck. Metals are sonorous; they produce a specific sound when struck with a hard object.

Ductility is the physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking. A ductile substance can be drawn into a wire

Malleability is a substance's ability to deform under pressure (compressive stress). If malleable, a material may be flattened into thin sheets by hammering or rolling. Malleable materials can be flattened into metal leaf.
