In this unit I learned about the extensive and intensive properties of matter. An extensive property is a property of matter that depends on the changes of the substances shape or amount. An intensive property is a property of matter that doesn’t depend on the substances shape or amount. The purpose of this investigation was to prove that density is

The characteristic of water as a shape can be used as an example of a physical property. Water can be frozen into ice‚ vaporized‚ or liquidized. The shape of water as a solid is
