Question

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

• A. X:- Malleability Y:- Metallic lustre Z:- Ductility
• B. X:- Malleability Y:- Ductility Z:- Metallic lustre
• C. X:- Metallic lustre Y:- Ductility Z:- Malleability
• D. X:- Metallic lustre Y:- Malleability Z:- Ductility

Answer 1

The correct option is B X:- Malleability

Y:- Ductility

Z:- Metallic lustre

- The ability of metals to be beaten into thin sheets is called malleablity. So, metals are used to make foils to wrap food.

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

-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.
