- Thermal energy always move from a hotter area to a colder area.
- Insulators like cardboard and foam can reduce the amount of thermal energy that is transferred into or out of a substance.
Why Do We Need To Know About Thermal Energy
Learning about thermal energy helps us understand how we cook food and keep warm. It’s all about moving heat around. This is important for staying comfortable and alive. For example, when we bake cookies or use hand warmers, it’s thermal energy that makes things hot or changes their state.
This knowledge can also help you find jobs in areas like food science, working with the army, or designing new products. Knowing about thermal energy means you can come up with better ways to keep things warm or cold, like in a thermos, or make fake snow, showing it’s useful for a lot of different things.
