Which of the following is not true about pool of water and a piece of ice

These are the answer choices that come along the question:

A. they have same composition

B ... they are in different states of mater

C. they have different chemical properties

D. they have different physical properties

Answer:

These is the one that is not true:

They have different chemical properties

Explanation:

Let's see every choice.

A. they have same composition

True. Both are water, so you know that their composition is H₂O: two atoms of hydrogen per each atom of oxygen.

The composition of the chemical compounds does no vary. Any pure water, in any physical state, in any place of the planet (or of the univers) will always have two atoms of hydrogen per each atom oxygen.

Each compound has its own chemical composition, which will be the same at any condition.

B. they are in different states of mater

True.

There are four states of matter: solid, liquid, gas, and plasma.

Ice is solid and the water in the pool is liquid. So, they are in different states of matter.

C. they have different chemical properties

False.

Being both pure water, as said before, they have the same composition.

This is they have the same kind of atoms, in the same ratio, and bonded together in the same way. That means that they have same chemical properties. This is, they react with the same substances.

D. they have different physical properties

Definetely, true. Physical properties include the state of the matter, the density, the color, the hardness, the viscosity, among others.

So, ice and liquid water have different physical properties.
