Question

Ice, water, and water vapor are chemically the same but they display different ___ properties.

Answer 1

Step 1 Understanding the concept:

• A physical property is a quality of matter that is independent of its chemical composition. For example, water exists in three forms, solid, liquid, and gas form but in all forms, the chemical composition of 2 atoms of hydrogen combined with 1 atom of oxygen remains the same
• Density, color, hardness, melting and boiling points, and electrical conductivity are all examples of physical qualities.
• Chemical properties are properties of a material that occur as a result of a chemical reaction or change in the material.
• For example magnesium on burning becomes magnesium oxide which is a white powder.

Step 2 Conclusion: Thus Ice, water, and water vapor are chemically the same but they display different physical properties.
