The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.

. Use the particle model of matter to explain why solids have a fixed shape but gases fill the shape of the container they are in. - Solids cannot be compressed because the particles are arranged in a regular pattern with almost no spaces between the particles. All matter is made up of particles that are incredibly small - much too small to see with the naked eye.
Scientists use the Particle Theory of Matter to describe temperature. Heat cool and compress atoms and molecules and watch as they change between solid liquid and gas phases. Topic 2 - States of matter and mixtures.
Expansion and Contraction States of Matter P1. There are forces between the particles. Solid liquid and gas.
It describes the arrangement movement and energy of particles in a. The particle theory of matter is a model that describes the arrangement and movement of particles in a substance. Particle model of matter to explain why solids have a fixed shape but gases fill the shape of the container they are in Liquids have very small spaces between the particles and so it is much harder to squash them together so they are not easily compressed.
21 Describe the arrangement movement and the relative energy of particles in each of the three states of matter. The particles have spaces between them. Compare and relate the characteristics of the three states of matter solid liquid and gas in terms of the arrangement and movement of the.
The three states of matter. The particles might be atoms molecules or ions. Liquids have very small spaces between the particles and so it is much harder to squash them together so they are not easily compressed.
Give an example of a liquid State a state of matter that cannot flow Give a state of matter that can be compressed Explain why sand is a solid and describe why someone might thing its. - Solids have a fixed shape and do not flow because the particles can vibrate but cannot move from place to place. The particle model describes matter in a very specific way.
Scientists use models to explain things we cant see without advanced equipment. Are solid liquid and gas. According to the particle theory all matter is made up of extremely tiny particles and each pure substance has its own kind of particle different from the particles from any other pure substance.
LEARNING TIP Are you able to explain the particle. Describe how the particles are arranged in solids liquids and gases. Liquids contain particles that are more loosely packed than solids but still closely packed compared to gases.
The particle model represents particles by small solid spheres. The water displaced by the object will be transferred to the measuring cylinder. Solids a solid will cause the molecules to vibrate faster and therefore cause the molecules to push each other further apart.
If an object can hold its own shape and is difficult to compress it is a solid. Solid liquid and gas. Describe the relationship between the motion of particles and temperature including the idea that there is a lowest possible temperature 273C known as absolute.
Solids contain particles that are tightly packed with very little space between particles. One of these things is an individual atom. Describe the particle structure of solids liquids and gases in terms of the arrangement separation and motion of the particles and represent these states using simple particle diagrams.
It can also be used to explain what happens in changes of state Figure 1 on the next page. The three states of matter can be represented by a simple model. All matter is made of tiny particles.
The kinetic theory of matter particle theory says that all matter consists of many very small particles which are constantly moving or in a continual state of motion. The particle theory of matter is. The particles of matter are always moving.
It has several key ideas. The particles can be atoms or combinations of atoms that are bonded. It describes four important aspects of matter.
For an irregular shaped object you can find its volume by submerging it in a eureka can filled with water. Thus the particle model can be used to explain the properties of solids liquids and gases. Use models to understand the behaviour of particles in the three states of matter.
The Particle Theory of Matter helps us think about how matter behaves. Describe the solid liquid and gaseous states of matter and explain their inter-conversion in terms of the kinetic particle theory and the energy changes involved. It also helps us explain why different matter has different properties.
The particles in matter are always moving. Particles are arranged and move differently in each state of matter. Adding heat to matter makes the particles move faster.
Describe the method to find the density of a solid object 1 use a balance to measure its mass 2 find the volume of the shape. The model is used to explain. In this model particles are represented by small solid spheres.
A scientific model of the structure of matter.
