Question

A thick glass tumbler cracks when hot water is poured into it.

• A. True
• B. False

Answer 1

The correct option is A True

1. When hot water is poured into a thick glass tumbler, the inner surface of the tumbler becomes hot and expands.
2. The outer surface of the tumbler does not expand quickly.
3. Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature.
4. Due to this uneven expansion, the glass tumbler cracks.

Hence, the statement is true.
