The physical properties of water from the listed items are:
- It is colorless and odorless in its pure form.
- When heated to 100 °C, water evaporates.
The first property describes the inherent characteristics of water without changing its chemical composition, making it a physical property. The third property describes a change in state (from liquid to gas), which is also a physical change.
The other two properties are not physical:
- It reacts with metals to form metal hydroxide and hydrogen gas (this is a chemical property).
- It decomposes to form hydrogen and oxygen (this is also a chemical property).
So, the physical properties of water in your list are the first and the third statements.
