Water is needed in our everyday lives and coincidentally, it’s everywhere. It is also what I am very fond of, being a swimmer myself. As a student, however, water is more than just the medium I swim in. It has very many interesting properties that I would like to discuss. So sit back, relax, and take a glass of water. You’ll thank me later.
Water has three states. In other words, it can be a solid, liquid, and even a gas under the right circumstances. As a solid, water becomes what is called ice. Water can become ice by reaching its freezing point, 0 ºC or 32 ºF. Solids, much like ice, have constant shape and volume. With this knowledge, mankind invented delicacies such as ice cream. Ice has also been used around the world by people to treat bruises and muscle pains due to its coldness.
The second state of water is what we see almost everywhere which is, of course, its liquid state. Now, before I get into the details of water as a liquid, I delved deeper and found out that water is a molecule made up of two hydrogen atoms and one oxygen atom. Upon learning this, I instantly thought that maybe fish can breathe underwater because their gills allow them to filter the hydrogen, leaving only the oxygen for breathing.
Anyway, going back to water as a liquid, there are many kinds of liquids in the world. Different drinks have been made for to satisfy the many, different tastes we, humans, have acquired. Examples are iced tea, carbonated drinks, tea and coffee. Just by closely examining our own bodies alone, we can see that we are made up of a liquid known as blood. Like solids, liquids have constant volume but have an indefinite shape. In other words, liquids can’t maintain a shape of its own and takes the shape of its container instead. This is because the particles of any liquid can slide past each other, making it much more malleable than solids.
Because of these properties of water when in liquid state, we are able to enjoy the hot summer by going to a beach or a pool to swim in, which brings me to the next state of water, gas. If water gets heated enough, 100 ºC or 212 ºF to be exact, it turns into water vapor. Unlike solids and liquids, gases have neither a constant shape nor a constant volume. They, however, take shape and size if put into a container. Clouds are observable examples of water in its gaseous state, as they are the result of water vapor being cooled just enough to form clouds. Aside from vapor, mankind has discovered other gaseous substances such as hydrogen and nitrogen.
Water and its three states of matter have been and continue to be useful in our everyday lives. Personally, I love water and all its forms. But, you already knew that.
