Multiple Choice

Which statement best compares and contrasts two physical properties of matter?

• Density and solubility are similar because they both involve water, but they are different because density involves dissolving a material and solubility involves floating or sinking a material.

• Density and solubility are similar because they both involve a material’s mass and volume, but they are different because density involves floating materials and solubility involves sinking materials.

• Boiling points and melting points are similar because they both involve changing the heat of a material, but they are different because boiling point involves adding heat to a material and melting point involves removing heat from a material.

• Boiling points and melting points are similar because they both involve the change in a state of a material, but they are different because boiling point involves a change from a liquid to a gas and melting point involves a change from a solid to a liquid.
