The video tutorial explains the phases of matter: solids, liquids, and gases, detailing their properties and energy levels. It introduces the phase change diagram, illustrating how heat energy affects matter's state. The tutorial also covers endothermic and exothermic changes, explaining how heat energy is absorbed or released during phase transitions.

Which of the following is NOT a phase of matter discussed in the video?

• Gas

• Liquid

• Plasma

• Solid

• They assume the shape of their container

• They have high amounts of energy

In which phase of matter are atoms more spread out than in solids but still have a fixed volume?

• Solid

• Liquid

• Plasma

• Gas
