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. There are some examples of liquids in our everyday life, like water, alcohol, and oil. We can conclude that the characteristic of solids is both its shape and volume will always stay the same. When a pen is put in a glass then moved to a table, both its shape and volume will stay the same. There are some examples of solids, like iron, copper, aluminum, wood and pen. Here’s the states of matter definition and examples: Then, pin one of the balloon until it is deflated.Both balloons are placed at the tip of the stick that has been balanced. Blow the two balloons until both have the same size.

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.

The tools and materials needed in this experiment are stick about 50cm long, two similar balloons, and a thread.

Prepare the tools and materials needed.

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. Does every solid substance, liquid substance, or even gas have a mass and take up some spaces? Yup.

What are the 3 states of matter
