Question

A thick glass tumbler cracks immediately when we pour hot water into it. This example is governed by which principle?

• A. Thermal expansion of solids
• B. Thermal expansion of liquids
• C. Thermal expansion of gases
• D. Anomalous expansion

Answer 1

The correct option is A Thermal expansion of solids

When hot water is poured into thick glass tumbler, the inner surface of the tumbler becomes hot and expands. The outer surface of the tumbler does not expand quickly. Due to this uneven expansion, the glass tumbler cracks.
