A substance has particles that are moving around each other. A scientist wants to increase particle speed to cause a phase change. The scientist transferred energy...

• INTO the substance and it change to a gas.

• INTO the substance and it change to a liquid

• OUT of the substance and it changed to a solid

• OUT of the substance and it changed to a liquid.

Both food started in the same phase. Energy was transferred into both of these jars. Only one of them changed phase. Which one was it and how did it change? (use the picture to help!)

• The SWEET food changed because the molecules were able to move fast enough to overcome the attraction between them. Its molecules now move away from each other.

• The SWEET food changed because the strong attraction between molecules made their movement slower. Its molecules now move around each other.

• The SOUR food changed because the weak attraction between molecules let them move faster. Its molecules now move away from each other.

• The SOUR food changed because the molecules were able to move fast enough to overcome the attraction between them. Its molecules now move in place.
