Which statement best compares and contrasts two physical properties of matter? Density and solubility are similar because they b
oth 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.
I believe the correct answer would be that b<span>oiling 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. Boiling and melting are phase changes that can happen to a substance however they differ in the process that happens.</span>
The last statement is the correct comparison of two physical properties. "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. " In addition, boiling point can also describe the temperature where a gas changes to a liquid. Likewise, melting point can also describe the temperature where a liquid changes to a solid. As to density and solubility, there is no direct relationship between the two. Density of a substance is its mass per unit volume. Whereas, solubility describes the ability a substance (solid, liquid or gas) dissolves in a solvent (solid, liquid or gas). The solvent is not necessarily water. Solubility depends on the complex physical and chemical properties of the solute and solvent, as well as the environment (temperature, pressure, etc.).
