Question

1. name three modern uses for quartz and explain why it is valuable in industry.

Explanation:

Quartz is used in watches due to its piezoelectric property which can convert mechanical stress to an electric charge and vice - versa, enabling accurate timekeeping. It is also used in glass - making as it provides high melting point and chemical resistance to the glass products. In electronics, quartz is used in semiconductors because of its stable physical and chemical properties, which are crucial for the performance of electronic components.

Answer:

1. Watches: Piezoelectric property for timekeeping.
2. Glass - making: High melting point and chemical resistance.
3. Electronics: Stable physical and chemical properties for semiconductors.
