1. solid and liquid
2. Evaporation changes liquid water to water vapour.
for #1: for example, it's raining, when it rains, the rain is water (liquid).
Or it's snowing, the snow is solid.
for #2: for example, when you are making tea, you need hot water, so you add heat, then the water lessens because it's transforming to gas, and sometimes you can see it.
