Understanding Changes in States of Matter

This video tutorial for 4th-grade social studies explains the changes in states of matter, including melting, freezing, evaporation, condensation, sublimation, and deposition. It highlights the role of energy, particularly heat, in these transformations. The video uses everyday examples like ice, chocolate, and steam to illustrate these concepts, making it relatable and easy to understand.

What is an example of a solid turning into a liquid?

• Ice cream melting

• Water freezing

• Camphor sublimating

• Steam condensing

What role does heat energy play in the melting process?

• It increases the temperature

• It has no effect

• It decreases the temperature

• It turns gas into solid
