What are some events that involve matter and energy

The heating process and the freezing process

Explanation:

When ice is heated up and begins to melt, the matter that makes up the ice (water) is infused with energy. The energy causes the ice to melt into a liquid and then into a gas. As the energy becomes greater and faster, the heat is more effective on melting/evaporating the ice/water.

When water is put in the freezer to chill, the cold air causes the energy cells to slow down, causing air to condense into water, and water to freeze into ice.

These are some examples that are easier to understand than other concepts, but there are many more of these occurrences in the world!
