Matter has two basic properties: physical and chemical properties. Which of these statements best describe physical properties?

• Physical properties behave identically for all matter under the same conditions

• Physical properties can be observed without changing the identity of a substance

• Physical properties are observed by seeing how a substance reacts with other substances

• Physical properties cause atoms and molecules to change structure when substances are mixed

If a solid was placed on the moon would it's density change?

• No, density is a measure of mass to volume ratio. Mass DOES change between planetary objects

• No, density is a measure of mass to volume ratio. Mass DOES NOT change between planetary objects

• No, density is a measure of weight to volume ratio. Weight DOES NOT change between planetary objects

• Yes, density is a measure of weight to volume. Weight DOES change between planetary objects
