Which one among the following would expand the most on being heated?

❌ B. Water: As a liquid, water has stronger intermolecular forces (such as hydrogen bonding) than air, which limits its expansion. Additionally, water exhibits anomalous expansion between 0°C and 4°C, where it actually contracts upon heating.

• ❌ C. Alcohol: While alcohol (liquid) has a higher coefficient of expansion than water and is often used in thermometers for this reason, its expansion is still much lower than that of any gas.

• ❌ D. Glass: As a solid, glass has the least expansion because its molecules are tightly packed in a fixed structure with strong bonds, allowing only for small vibrations rather than large increases in volume.
