Which of the following materials can be used to make window panes? Give a reason for your answer.
(a) glass
(c) nylon cloth
(b) plastic
(d) cardboard



Answer :

To make window panes, the material that is commonly used is glass. Glass is preferred for window panes because it is transparent, allowing light to pass through while providing insulation. Glass is also durable and can withstand various weather conditions, making it suitable for long-term use. Additionally, glass can be easily cleaned and maintained, keeping the windows looking clear and allowing light to enter the room without obstruction. In contrast, materials like nylon cloth, plastic, and cardboard are not ideal for making window panes. Nylon cloth is not transparent and cannot provide the necessary structural support for a window. Plastic may be transparent but is less durable than glass and can be easily scratched or damaged. Cardboard is not transparent, lacks durability, and cannot provide insulation like glass does. Overall, glass stands out as the most suitable material for making window panes due to its transparency, durability, insulation properties, and ease of maintenance.
