## 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.

## What is the arrangement of particles in solids?

In a solid, particles are packed tightly together in a regular pattern. Solids have fixed shaped that are hard to break apart because individual particles do not have enough energy to escape individually. Solids are ALWAYS in a regular lattice pattern.

In which states are the particles randomly arranged?

Gases

• are much further apart;
• are entirely free to move because the forces between them are weak;
• are randomly arranged;
• move quickly and randomly in all directions.

In which state of matter are the particles mostly touching but arranged in a random way?

In which state of matter are the particles mostly touching but arranged in a random way? The particles are mostly touching but have a random arrangement in a liquid. In a solid, the particles are mostly touching but have a regular arrangement.

### What is particle model of matter?

The particle theory of matter is a model that describes the arrangement and movement of particles in a substance. The model is used to explain the physical properties of solids, liquids and gases.

### How do arrangements of molecules affect the state of matter?

Answer: Matter in the solid state maintains a fixed volume and shape, with component particles (atoms, molecules or ions) close together and fixed into place. Matter in the liquid state maintains a fixed volume, but has a variable shape that adapts to fit its container.

How would you describe the three states of matter?

Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.

Why do particles move matter?

Particles of matter are attracted to each other, so they tend to pull together. The particles can move apart only if they have enough kinetic energy to overcome this force of attraction. If particles do not have enough kinetic energy to overcome the force of attraction between them, matter exists as a solid.

## In which of these 3 states of matter do the particles have the most energy?

gas
All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy.

## Which state of matter has particles with the most energy?

A pure substance in the gaseous state contains more energy than in the liquid state, which in turn contains more energy than in the solid state. Particles has the highest kinetic energy when they are in the gaseous state. Kinetic energy is related to heat (also called thermal energy).

What are the three states of matter in physics?

The three states of matter. are solid, liquid and gas. The particle model represents particles by small, solid spheres. It describes the arrangement, movement and energy of particles in a substance.

What is the particle model of matter?

This model explains the properties of substances in their different states, as well as changes of state. The three states of matter are solid, liquid and gas. The particle model represents particles by small, solid spheres.

### What are the characteristics of the three phases of matter?

The three normal phases of matter have unique characteristics which are listed on the slide. 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.

### What is the particle arrangement for gases?

The particle arrangement for gases is random and the particles are spread out. They fly around, colliding with each other and the sides of their containers. There’s lots of space between the particles, meaning that gasses can be compressed. The more they are compressed, the more they collide with their container and each other.
