Ice contracts on heating.
- When ice is heated, it converts to water and expands at a temperature of 0° C, and then when it is heated further between 0°C and 4°C, instead of expanding it begins to contract.
- This phenomenon is known as anomalous expansion of water.
- All the other options only expand on heating due to the increase in kinetic energy of the molecules.
- Hence the correct option is ice.
