Expansion of a substance on heating depends on:
Nature of the substance:
- Different substances have different atomic and molecular structures which affect how they expand when heated.
- Some substances have a higher coefficient of thermal expansion, meaning they expand more when heated compared to others.
- The arrangement of atoms or molecules in a substance can also affect how it expands when heated.
Rise in temperature:
- The increase in temperature is directly proportional to the expansion of a substance.
- When a substance is heated, the kinetic energy of its particles increases, causing them to move more rapidly and take up more space.
- The higher the temperature, the greater the expansion of the substance.
Both A and B:
- The expansion of a substance on heating depends on both the nature of the substance and the rise in temperature.
- The nature of the substance determines its inherent properties that affect expansion, while the rise in temperature directly influences the extent of expansion.
- Therefore, the correct answer is option C - both the nature of the substance and the rise in temperature play a crucial role in determining how a substance expands when heated.
