we can call it matter everything that occupies space in space and has mass. It is the body of things, objects, animals, plants and people.
They exist three physical states in which subjects can present themselves: the solid, the liquid and the gas. These states vary according to the conditions they are in, depending on the temperature and pressure of the atmosphere.
in the state solid, the particles are agglomerated, condensed, tightly bound, giving shape to the object or the body. As an example of solid state we have the chair, the table, the pencil, the iron, a wooden stub, among many others. Ice is water in solid state. the solids are measured in mass units: milligrams, grams, kilograms, tons, among others.
Solid State Matters
in the state liquid, the particles (what we call little pieces) meet less united, not having a determinate form. We can see that liquids always adapt to the shape of the container. in which they are placed. You just have to remember a glass of water, a vase of flowers or even the water spilled on the floor. the liquids
are measured in volume units, in milliliters, liters, cubic centimeters, etc., with the fundamental unit for this type of measurement being the cubic meter (m3). A liquid body has only defined volume.
liquid state of matter
In the gaseous state, bodies do not have their own shapes either, but they spread through space. In this state, the bits and pieces are connected very weakly, leaving the body (gas) with no defined shape or volume. We can observe the gaseous state when we take very hot bath and a whitish smoke appears from the water. This smoke is the least condensed water, loosely united, being spread through the air. Another example is when mom opens a pot of very hot food and a little smoke comes out of it. This is vapor, that is, the body in a gaseous state.
The measurements of gaseous are made through special apparatus, it is not possible for man to measure it, as in the case of solids and liquids.
