States of Matter & Phase Changes

Master states of matter and phase changes! Learn about solids, liquids, gases, and molecule movement.

Phase Change Diagram Click on the blue blinking dots and a box will appear that you can type in. Label the diagram with the following terms:solid liquid gas freezing melting condensation evaporation solid liquid gas freezing melting condensation evaporation Molecules in Matter Draw a picture of the molecules in each state of matter. What happens to the molecules in a liquid when heat energy is removed. What happens to molecules in a liquid when heat energy is added? Use the word bank. Type the word on the line that completes the statement.Word Bank:phase change kinetic melting point condensation heat energy stays the same The melting point is the temperature at which a solid changes to a liquid. As heat energy is taken away from a substance the molecules movement slows down. This also means that there is less kinetic energy within the molecules. Condensation is when a gas changes into a liquid as heat is taken away. A phase change is a change in states of matter due to adding or removing heat energy. Think of the Phase Change Diagram: During a phase change the temperature stays the same until the entire substance changes to the next state of matter. Think of the Phase Change Diagram: During a phase change the heat energy continues to be added or removed.
