Every object inside our universe consist of substance or matter. Humans, animals, and even plants consist of substance or matter. Every matter consists of thousands of millions of particles. Matter can be defined as something that has mass and takes up space. Depending on its states, matter can be divided into three main groups, solid, liquid, and gas.
There are several examples of states of a matter around us, like in our house, schools, street, etc.
Does every solid substance, liquid substance, or even gas have a mass and take up some spaces? Yup. Does gas, something that can’t be seen by naked eyes, considered as a matter? How do we prove it? Here are some ways to prove that gas has mass and takes up space.
- Prepare the tools and materials needed. The tools and materials needed in this experiment are stick about 50cm long, two similar balloons, and a thread.
- Knot a thread right in the middle of the stick until it is balanced (the stick is in a horizontal position) and hang it in a certain place.
- Blow the two balloons until both have the same size. Both balloons are placed at the tip of the stick that has been balanced.
- Then, pin one of the balloon until it is deflated. What happened? What is your conclusion?

Characteristics of a matter
Here’s the states of matter definition and examples:
There are some examples of solids, like iron, copper, aluminum, wood and pen. When a pen is put in a glass then moved to a table, both its shape and volume will stay the same. We can conclude that the characteristic of solids is both its shape and volume will always stay the same.
There are some examples of liquids in our everyday life, like water, alcohol, and oil. We take water as an example, if water is poured into a bottle then poured again into a glass then into a bowl, we can observe that the shape of water always follows its container without reducing its volume. From that example we can conclude that the characteristic of liquids is its volume will always stay the same but its shape will always change depending on its container. also read: Gas Laws Definition, Formulas, and Examples
There are some examples of gases that we can found, like the air around us and helium gas that is used to fill the air balloon. To determine the characteristic of gas, we can take room sprays as an example. When we spray room sprays in the corner of a room, we can smell the smell of the room sprays immediately even though we are far from the place where the room spray is sprayed.
It is because that gases spread the aroma of that room sprays so that the volume of that room sprays changed and always filled up the room. From that example we can conclude that the characteristic of gases is that its volume always changed depending on the room that it fills and its shape will also change depending on the room that it fills. To sum up, that’s the states of matter definition and examples you need to learn.
Changes in states of matter
An experiment to prove that a state of matter can be changed is following the steps below.
- Prepare the tools and materials needed for the experiment. The tools and materials needed are fireproof chemistry glassware, spirit lamp, wire gauze, laboratory tripod, and several blocks of ice.
- Put several blocks of ice inside the fireproof chemistry glassware
- Put that glass above the tripod. The wire gauze serves to spread the heat so that the heat does not centered to a certain place.
- Light up the spirit lamp and observe what happened inside the glass.
The result of the experiment is as the following explanations. After the heating occurs for a few minutes, the blocks of ice turned its states into water. And after a few minutes, the water turned its state into a steam. From that experiment, we can conclude that the states of a matter can be changed. also read: Measuring pH Value of Water in Chemistry
Camphor is an example of a changing in state of matter from solids into a gas. As we all know that camphor that is placed inside a wardrobe will become smaller from time to time until it is gone. When we open the wardrobe, we will immediately smell the fumes of a camphor and the clothes will become fragrant. This example shows us that camphor (which is solids) has turned into a fumes (which is a gas).
Changing in States of a Matter
These are the terms of the changing of state of a matter and its explanation.
- It is a change of state where the liquids turned into a gas. Examples of vaporization are hot tea gets cool over time and wet clothes dry in the sun.
- It is a change of state where solids turned into liquids. Example of melting is when an ice cube melts.
- It is a change of state where liquids turned into solids. Example of freezing when water freezes into an ice cube when it is put inside a freezer.
- It is a change of state where a gas turned into liquids. Example of condensation is when a dew forms in the morning. also read: Human Activities Affecting The Life of Ecosystems
- It is a change of state where solids turned into a gas without going through the liquid state. Example of sublimation is solid carbon dioxide. Solid carbon dioxide is also known as dry ice and it sublimates at a room temperature. Putting dry ice in a room temperature will turn it into a gas.
- It is a change of state where gas turned into solids without going through its liquid state. Example of deposition is one may or may not know. It occurs when a gas turned into a frost in a cold winter morning.
By reading the above article, we know a detailed explanation of a matter, its state, and how it changes from one state to another. Hopefully, this article about states of matter definition and examples will help you know better about states of matter and gives you a helpful information.
