A student is investigating chemical changes by using different materials. Which investigation would provide evidence of a chemical change

and why?

• Melting a solid with fire would provide evidence of a chemical change because the solid would change shape.

• Cutting cardboard into many smaller pieces would provide evidence of a chemical change because the pieces cannot be put back together.

• Placing a solid into hot water and stirring while the solid dissolves would provide evidence of a chemical change because the dissolved material is lost.

• Combining two liquids that give off heat and gas would provide evidence of a chemical change because the particles react to make a new material with different properties.
