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.
