Particle Theory of Matter STUDY Flashcards Learn Write Spell Test PLAY Match Gravity Created by Jo_Harris4 Terms in this set (20) List the 5 points of the Particle Theory of Matter. 1. All Matter is made up of extremely small particles 2. Each pure substance has its own kind of particle, different from the particles of other pure substances 3.
What are the five points of particle theory?
The Five points of Particle Theory are: 2)All particles in a pure substance are the same. 3)Particles have spaces between them, regardless of size. 5)The particles in a substance are attracted to eachother. The strength of the attractive force depends on the particle. 2)All particles in a pure substance are the same.

What are the 5 main points of the particle theory?

What are the main points of particle theory?
All matter is composed of tiny indivisible particles too small to see. These particles do not share the properties of the material they make up. There is nothing in the space between the particles that make up matter. The particles which make up matter are in constant motion in all physical states.
What are the 4 parts of the particle theory?
The Five points of Particle Theory are:All Matter is made up of tiny particles, invisible to the naked eye.All particles in a pure substance are the same. ... Particles have spaces between them, regardless of size.Particles move faster and spread more when heated.More items...
What does the particle model explain?
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.
Why is the particle theory important?
Scientists find the particle model useful for two reasons. First, it provides a reasonable explanation for the behaviour of matter. Second, it presents a very important idea—the particles of matter are always moving. Matter that seems perfectly motionless is not motionless at all.
What is the particle theory of matter Grade 7?
The particle theory of matter is: A scientific model of the structure of matter; 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.
What are the 3 states of matter?
They are very compressible (particles are widely spaced). There are three states of matter: solid; liquid and gas. They have different properties, which can be explained by looking at the arrangement of their particles.
Who discovered the particle theory?
philosopher DemocritusThe particle theory of matter was not so much discovered as it was formulated, and that formulation began in ancient Greece. The person who is credited with having conceived of the idea that the world is composed of tiny, indivisible particles is the philosopher Democritus, who lived from 460 to 370 BCE.
What are the 3 principles of kinetic theory?
What are the three principles of kinetic theory?...No energy is gained or lost during the collision between molecules.Molecules take up a negligible amount of space in relation to the container space they occupy.The molecules are in constant linear motion.
What is the particle theory of matter Grade 7?
The particle theory of matter is: A scientific model of the structure of matter; 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.
What are the 3 states of matter?
They are very compressible (particles are widely spaced). There are three states of matter: solid; liquid and gas. They have different properties, which can be explained by looking at the arrangement of their particles.
What are the 12 particles of matter?
The 12 elementary particles of matter are six quarks (up, charm, top, Down, Strange, Bottom) 3 electrons (electron, muon, tau) and three neutrinos (e, muon, tau). Four of these elementary particles would suffice in principle to build the world around us: the up and down quarks, the electron and the electron neutrino.
What does particle theory explain?
The particle theory explains- The properties of matter. What happens when matter undergoes physical changes such as melting, boiling, and evaporation.
Why is water an exception in the particle model of matter?
Water behaves differently than most of other substances because its particles are less densely packed in their solid-state (ice) than in their liqu...
What are the limitations of the particle theory of matter?
The particle theory does not take into account: The size and shape of particles The space between particles Furthermore, the particle theory does n...
Why is the particle theory important?
The particle theory is useful for two reasons. First, it provides a reasonable explanation for the matter’s behaviour. Second, it conveys an import...
What is the energy involved in the motion of particles?
Kinetic energy is involved in the motion of particles. When the temperature rises, the kinetic energy of the particles increases thus, aking partic...
Why do water particles move faster?
When the spoon is added the particles bump into the spoon causing the particles in the spoon to begin moving faster
What happens to the volume of particles as they heat up?
As particles heat up, they begin to move faster and spread apart, so the volume will be increased
What is matter made of?
1. All Matter is made up of extremely small particles
Why does heat change?
Thermal Energy also known as Heat causes changes because heat moves from an object with a higher temperature to an object with a lower temperature
Which molecules are free to move around?
The Molecules in a liquid or a gas are free to move around
Why do particles move faster?
Particles move faster (vibrate faster) and spread out more because the heat transmits more energy into them , causing the particles to vibrate more rapidly. For example, it's just like when you step on a very hot pavement in your bare feet. That makes you move a lot faster.
What is the strength of attractive force?
If a particle is negative, it will attract a positive particle and they will stay close together, rather than apart, unlike a positive vs positive, and negative vs negative.
Is a pure substance the same as a particle?
2)All particles in a pure substance are the same. Different substances are made up of different particles
What is matter made of?
All matter is made up of tiny and invisible particles, called atoms . There is not much to say, considering the headline explains it. Everything that exists is made up of particles, be it food, water, air, even the phone in your pocket! For human purposes, matter cannot exist without particles.
Do particles have space?
Particles have space between them, regardless of size. E.i: In a solid, all of the particles still have space between them, but they are much smaller than gasses' particle's spaces . In a liquid, the spaces between the particles are bigger than a solid's, but much smaller than a gasse's. Particles are always vibrating against each other.
