Exploring the States of Matter and Thermal Energy

This lesson, led by Kayleigh, explores how heat affects matter, focusing on the three common states: solid, liquid, and gas. It explains the properties of each state and how they change when heat is applied or removed, leading to transitions like melting, freezing, evaporation, and condensation. The lesson includes a Phet simulation to visualize these changes, emphasizing the role of thermal and kinetic energy in state transitions.

What are the three most common states of matter?

• Solid, Liquid, and Gas

• Solid, Liquid, and Plasma

• Solid, Gas, and Plasma

• Liquid, Gas, and Plasma

How do solids behave when moved to a new container?

• They keep both shape and volume

• They change both shape and volume

• They change volume but keep the same shape

• They change shape but keep the same volume

Why is it hard to compress a solid?

• Because the atoms and molecules are loosely packed

• Because the atoms and molecules are tightly packed and hardly move

• Because the atoms and molecules are moving very fast

• Because the atoms and molecules are in a random pattern

In the Phet simulation, what does the red line on the phase diagram represent?

• The current temperature
