Select all statements that are true when comparing a puddle of water and a cube of ice.

Question

They have the same molecular composition.
They are different states of matter.
They have different chemical properties.
They have different physical properties.

Answer 1

The following statements are true when comparing a puddle of water and a cube of ice:

1. They have the same molecular composition. - True. Both water (H₂O) and ice are made up of the same molecules, just arranged differently.

2. They are different states of matter. - True. Water is in a liquid state, while ice is in a solid state.

3. They have different chemical properties. - False. The chemical properties of water and ice are the same because they are composed of the same molecules.

4. They have different physical properties. - True. Water and ice have different physical properties, such as density, melting point, and state of matter.

So, the true statements are:

• They have the same molecular composition.
• They are different states of matter.
• They have different physical properties.
