Which statements below are an appropriate hypothesis in response to this question? Check all that apply. If a substance changes state of matter (e.g., liquid to gas), then this is a physical change because the original properties of the substance have not changed. If a substance undergoes a physical change, then it will retain most of its original properties because no new substance is formed. If a substance undergoes a chemical change, then it will not retain its original properties because a new substance is formed. If a precipitate is formed when two substances are mixed, then a chemical change has taken place because precipitates are new substances.

Changes of matter from liquid to gas is a physical property because original properties of the substance have not changed, and formation of precipitation is a chemical property because all original properties are changed.

What are physical and chemical properties?

Physical properties are those properties which can be seen by simple eyes and chemical properties are those properties sometimes which are not observable by simple eyes.

Physical properties: This property of any substance changes the structure of the given substance but not the original properties.
Chemical properties: This property of any substance changes the bonding as well as structure of the substance and in addition of this their original properties also changes.
Formation of a precipitate is an example of chemical change because new product is formed.

Hence, option all options are correct.
