Question

Do all materials respond to heat in the same way? Give an example to support your answer.

Answer 1

No, not all materials respond to heat in the same way. Different materials have different thermal properties, leading to varying responses when subjected to heat. For example, metals generally have high thermal conductivity and expand when heated. This can be observed in a metal wire, which elongates when heated due to the increase in molecular motion and interatomic spacing. In contrast, ceramics have low thermal conductivity and expand less when heated. This can be seen in a ceramic plate, which remains relatively stable in shape when exposed to heat.
