# How do you describe the phases of matter?

## How do you describe the phases of matter?

The states in which matter can exist: as a solid, liquid, or gas. Examples of phase changes are melting (changing from a solid to a liquid), freezing (changing from a liquid to a solid), evaporation (changing from a liquid to a gas), and condensation (changing from a gas to a liquid). …

## How does the arrangement of particles in matter explain its properties?

The looser arrangement of particles is what allows liquids to take on the shape of their container. The intermolecular forces between particles in liquid determine properties like viscosity and surface tension. Particles in a liquid are higher in energy than the solid state, but lower in energy than the gas state.

How are the molecules arranged in a solid matter?

In crystalline solids, the atoms, ions or molecules are arranged in an ordered and symmetrical pattern that is repeated over the entire crystal. The smallest repeating structure of a solid is called a unit cell, which is like a brick in a wall. Unit cells combine to form a network called a crystal lattice.

### What are the 3 states of matter and their characteristics?

There are three common states of matter:

• Solids – relatively rigid, definite volume and shape. In a solid, the atoms and molecules are attached to each other.
• Liquids – definite volume but able to change shape by flowing. In a liquid, the atoms and molecules are loosely bonded.
• Gases – no definite volume or shape.

### What are the three states of matter how are molecules arranged in them?

solid: Relatively rigid, definite volume and shape. In a solid, the atoms and molecules are closely bonded that they vibrate in place but don’t move around. liquids: Definite volume but able to change shape by flowing. In a liquid, the atoms and molecules are loosely bonded.

How are molecules arranged in the three states of matter?

The arrangement of molecules in the three states of matter is different. The molecules in a solid are packed close to each other. The only movements they make are small vibrations about their fixed positions. The spaces between molecules are known as inter-molecular spaces. These are almost negligible in solids.

## What makes up the three phases of matter?

Matter is something that has mass and volume (takes up space). Matter can be found in several phases or states. The three most common phases of matter on Earth are solids, liquids and gases. Less commonly, we can also find matter as plasma or Bose-Einstein (BE) condensate. Solids have a fixed shape and volume.

## What do you mean by molecular arrangement in liquids?

Arrangement in liquids: The molecules in a liquid can move about a little. They are less tightly packed than in solids, that is, they have bigger intermolecular spaces. The molecules of liquids do not have fixed positions. The intermolecular forces of attraction between the molecules of a liquid are weaker than those in solids.

How are molecules bound in the solid phase?

In the solid phase the molecules are closely bound to one another by molecular forces. A solid holds its shape and the volume of a solid is fixed by the shape of the solid. In the liquid phase the molecular forces are weaker than in a solid.
