You are looking at a substance in a sealed jar. At first the substance's molecules are moving around each other. What will happen if you transfer energy into the substance and causes a phase change?

After the phase change, the substance’s molecules will move . . .

• faster, and the substance will be a liquid.

• faster, and the substance will be a gas.

• 
  slower, and the substance will be a solid.

• slower, and the substance will be a liquid.
