Four properties of water are listed.

It is colorless and odorless in its pure form.
It reacts with metals to form metal hydroxide and hydrogen gas.
When heated to 100 °C, water evaporates.
It decomposes to form hydrogen and oxygen.

Which are the physical properties of water?

1 answer

The physical properties of water from the listed items are:

  1. It is colorless and odorless in its pure form.
  2. 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.
