Do any substances (except water) exist in more than one form (solid, liquid, gas) at particular temperature and pressure?
Can the same substance have different properties in different forms?
Yes, the same substance can have different properties in different forms. For example, solid water (ice) is less dense than liquid water, so it floats. Similarly, diamond and graphite are both forms of carbon, but they have very different properties due to their different crystal structures.
