How does thermal expansion work and what is an example?

11. Eleanor M. Savko
12/12/2017
Thermal expansion is the increase in volume of a substance because of an increase in temperature. In other words, higher temperatures mean particles are moving faster and spreading out, causing the increase in volume. An example would be the air in a hot air balloon.

Explain how heat is transferred when liquid water becomes ice.

21. Eleanor M. Savko
12/12/2017
Thermal energy is transferred from the warmer water to the colder air surrounding the water and the water’s molecules slow down and become more tightly held together.
