Question

Identify the properties of the metals from the uses mentioned in the table given below.
$$\begin{array}{cc}\text{Uses}& \text{Property}\\ \text{Used to make foils to wrap food}& \text{X}\\ \text{Used to make electric wires}& \text{Y}\\ \text{Used to make ornaments}& \text{Z}\end{array}$$

Answer 1

X - Malleability:
The ability of metals to be beaten into thin sheets is called malleablity. Therefore, metals are used to make foils to wrap food which are malleable.

Y - Ductility:
The ability of metals to be drawn into wires is called ductility. Therefore, ductle metals are used to make electric wires.

Z - Lustrous:
Metals have a unique ability to reflect light. This results in a shiny surface and this property of metals is known as metallic lustre. Hence, metals are used to make ornaments.
