False: Heat is the transfer of energy between two objects or systems due to a temperature difference. It is not the total energy of a group of particles.
Do all materials respond to heat in the same way? Give an example to support your answer.
No, different materials respond to heat in different ways. Some materials can conduct heat well, while others are poor conductors. For example, metals such as copper or aluminum are good conductors of heat, meaning they can transfer heat quickly and efficiently. This is why metal pots and pans heat up quickly when placed on a stove.
On the other hand, materials like wood or plastic are poor conductors of heat, also known as insulators. They tend to resist the flow of heat, so they may not heat up as quickly as metals when exposed to the same heat source. An example of this can be seen when touching a metal spoon and a wooden spoon that have been left in a pot of boiling water. The metal spoon will feel hot much faster than the wooden spoon since it conducts heat better.
