Science Air Test

Students are investigating chemical changes that occur in different materials. Which TWO investigations would provide evidence of a chemical change?

• Placing a liquid in a freezer until the liquid becomes a solid would provide evidence of a chemical change because the state of matter changes.

• Using a saw to cut a solid into two different pieces would provide evidence of a chemical change because the pieces cannot be put back together

• . Using a hot plate to heat a solid until it changes color and releases an odor would provide evidence of a chemical change because the particles cannot be changed back.

• Placing two different liquids together in a beaker and observing that a solid forms when they mix would provide evidence of a chemical change because a new material is formed.

• Placing a mixture containing a solid and a liquid on a windowsill and letting the liquid evaporate would provide evidence of a chemical change because the evaporated material is lost
