A chef finds a sealed container consisting of an ingredient that goes into his restaurant’s secret sauce. The ingredient’s molecules are moving in place. What will happen if the chef causes the ingredient to change phase by transferring energy into it?

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

• faster, and the ingredient will be a solid.

• faster, and the ingredient will be a liquid.

• slower, and the ingredient will be a solid.

• slower, and the ingredient will be a liquid.
