States of Matter
Hello reader. We are going to discuss about another topic of science in this post. The topic is related to physics and chemistry. The topic is "states of matter".
What is a state of matter? A state of matter is a distinct form in which matter can exist. There are 4 states of matter: solids, liquids, gases, and plasma. But let's discuss about solids, liquids, and gases first.
In a solid, the particles are tightly packed together. The particles are held together by the forces of attraction. The forces of attraction are so strong that the particles cannot move freely, but they can vibrate. As a result, a solid has a stable, definite shape, and a definite volume. Solids can only change their shape by force, as when broken or cut. Solids however can change into liquids by being heated, which causes the particles to vibrate strong enough to escape the forces of attraction. This process of changing is called melting. Liquids can also change to solid if the temperature is cool enough.
The particles of a solid.
A liquid is a fluid that follows the shape of it's container and retains a constant volume, without pressure. The volume is definite if the temperature and pressure are constant. The liquid can change to a gas if the temperature is hot enough.

In a gas, the particles can move freely. The particles are not attracted at all. It can not only follow the shape of its container, but it also can fill it. The gaps between the particles in a gas are big.
