3. Identify two household products that look similar to each other. List the physical
properties that are the same for the products and identify a property that would
allow you to tell them apart. For example, water and vinegar are both
transparent, colourless, liquids with low viscosity. However, vinegar has a strong
odour while water is odourless.

substances?
