Water moves in clumps, owing to its elastic property. As such, roots of plants and our blood vessels have water moving through them, known as capillary action. To demonstrate this, twist a piece of paper towel into a long sausage shape. Put 1 oz. of water in a tall glass, then place the paper towel vertically inside it. Observe the movement of water through the fibers of the paper towel -- you will see that the towel slowly gets wet from the bottom upwards as the water moves through it.
When water freezes it expands and consequently takes up more space as a solid, or ice. This explains why pipes burst during winter in some instances. Get a full glass of warm water and place an ice cube in the top. Assess what happens as the water changes state from solid to liquid -- or melts. Naturally, you might expect the glass to overflow with water. In fact, because the ice cube is floating it has displaced water in the glass. As it melts, the water fills this space. However, because it is denser than ice, it has enough space already in the glass, and the water does not overflow.
Condensation is the process of turning water vapor (gas) into water droplets (liquid). You may have seen this on the bathroom mirror after a hot shower, or inside a car on a cold day. To demonstrate this transient property of water, all you need is a cold window. Stand in front of the window pane and breath heavily onto the glass. Identify the white haze the glass -- this is condensation. If you look closely and continue to breath onto the glass, it will become more evident that this is made up of tiny water droplets.
Water boils at 212 degrees Fahrenheit. As water is heated, the heat energy enables the molecules of the water to move quickly. This enables them to break away into a gaseous state. Once the boiling point is reached, the water will not get hotter, as it is using all available heat energy. Heat a pan of water over a flame and put a thermometer in the water. Watch the temperature rise and note what you see happening on the surface of the water. When the boiling point is reached, you will see large bubbles.
