Answer 1

No, not all materials respond to heat in the same way. Different materials have different thermal properties, which determine how they expand or contract when heated or cooled. For example, metals are generally good conductors of heat and expand when heated. This can be observed when a metal object, such as a metal spoon, is placed in a hot liquid. The spoon will expand and can be slightly deformed due to the heat. In contrast, materials like ceramics have lower thermal conductivity and expand much less when exposed to heat.
