Scientists digging in a cave found an unknown substance. The scientists found that the substance’s molecules were moving around each other. The scientists increased the speed of the substance’s molecules and caused a phase change. How did the scientists do this, and how did this affect the substance?

• The scientists transferred energy INTO the substance, and the substance changed into a gas.

• The scientists transferred energy INTO the substance, and the substance changed into a liquid.

• The scientists transferred energy OUT OF the substance, and the substance changed into a solid.

• The scientists transferred energy OUT OF the substance, and the substance changed into a liquid.
