Answer:
Energy added to solid water will turn it into liquid water; add energy into liquid water and it will be turned into water vapor.
Explanation:
Adding energy is basically adding heat; the more heat, the more excited the molecules of H2O gets. In solid water, the molecules aren't really moving because they don't have a lot of energy, so it is solid. In liquid water (which is water in room temperature), it has a medium amount of energy; the molecules aren't stuck together but it isn't completely dispersed, so it is in liquid form. However, in water vapor, the energy becomes very high and the molecules are excited. The hydrogen bonds holding the molecules together break and the water is released as a vapor.
Most solids a) are dense and difficult to compress.
Most solids are closely compacted, their molecules are close together and vibrate. They don't move freely like gas or water molecules do.
They are difficult to be squeezed or flattened.
