Which of the following is a physical property of water?
a. it is a liquid.
b. it reacts with many substances.
c. both of the above

Hi there!

First of all, you have to pay attention to the question, and they are asking for something physical, and physical means to be seen on the outside.

The answer is A because you can clearly see that water is a liquid. Being a liquid is a physical property.

It wouldn't be B because I believe it would be a chemical property to react with many substances.

Hope this helps! :D
