There are five main points to the particle theory: 1. All matter is made up of particles 2. All particles in a pure substance are identical (no two different  pure substances have the same particles) 3. All particles have space between them 4. All particles are always moving – more energy (heat) produces  more movement 5. All particles are attracted to one another ]]> 2017-12-29 01:31:08 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218130136 What is Particle Theory pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218131302 The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles in which are constantly moving or in a continual state of motion. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles]]> 2017-12-29 02:47:28 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218131302 More about Particle Theory pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218131337  Particle Theory are made up of tiny  atoms that come in many shapes and sizes.Atoms are in every piece of matter,Example:-Gold,Silver,Aluminium,and Organism.Particle Theory are found in every thing on earth because Particle Theory is matter.   ]]> 2017-12-29 02:49:53 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218131337 MORE INFO The particles are atoms, molecules or ions. Use of the general term 'particle' means the precise nature of the particles does not have to be specified.Particle theory helps to explain properties and behaviour of materials by providing a model which enables us to visualise what is happening on a very small scale inside those materials. As a model it is useful because it appears to explain many phenomena but as with all models it does have limitations. pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218270968 2018-01-02 01:14:47 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218270968 Kinetic particle theory ,The kinetic particle theory explains the properties of the different states of matter. The particles in solids, liquids and gases have different amounts of energy. They are arranged differently and move in different ways.The table summarises the arrangement and movement of the particles in solids, liquids and gases, and shows simple diagrams for the arrangement of these particles. pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218274212 2018-01-02 03:14:55 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218274212 The particle theory of matter is: pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218355733 A scientific model of the structure of matter; according to the particletheory, all matter is  made up of

Francis Sears and Mark Zemansky, in University Physics, give the example of calculating the landing location and speed of a baseball thrown in the air. They gradually strip the baseball of most of its properties, by first idealizing it as a rigid smooth sphere, then by neglecting rotation, buoyancy and friction, ultimately reducing the problem to the ballistics of a classical point particle.[5] The treatment of large numbers of particles is the realm of statistical physics. pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218419320 2018-01-03 01:47:06 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218419320 The term 'particle' is rather general in meaning, and is refined as needed by various scientific fields. Something that is composed of particles may be referred to as being particulate.However, the noun 'particulate' is most frequently used to refer to pollutants in the Earth's atmosphere, which are a suspension of unconnected particles, rather than a connected particle aggregation. pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218419554 2018-01-03 01:54:03 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218419554 Particles can also be classified according to composition. Composite particles refer to particles that have composition – that is particles which are made of other particles.For example, a carbon-14 atom is made of six protons, eight neutrons, and six electrons. By contrast, elementary particles (also called fundamental particles) refer to particles that are not made of other particles. pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218422278 2018-01-03 03:01:11 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218422278 Both elementary (such as muons) and composite particles (such as uranium nuclei), are known to undergo particle decay. Those that do not are called stable particles, such as the electron or a helium-4 nucleus. The lifetime of stable particles can be either infinite or large enough to hinder attempts to observe such decays. In the latter case, those particles are called "observationally stable". In general, a particle decays from a high-energy state to a lower-energy state by emitting some form of radiation, such as the emission of photons. pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218425203 2018-01-03 04:10:34 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218425203 Colloidal particles are the components of a colloid. A colloid is a substance microscopically dispersed evenly throughout another substance.Such colloidal system can be solid, liquid, or gaseous; as well as continuous or dispersed. The dispersed-phase particles have a diameter of between approximately 5 and 200 nanemeters pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218425514 2018-01-03 04:18:38 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218425514 Properties of Solids, Liquids, and GasesAll materials are made of tiny particles. These are called atoms. Sometimes atoms join together to form molecules. Scientists talk about different materials by talking about these particles. They talk about how the atoms (or molecules) are arranged. This helps scientists explain solids, liquids, and gases. pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218556910 2018-01-03 16:36:05 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218556910 Solids pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218558606 In solids, the particles are arranged in a regular pattern. They are held together by strong forces. This is why solids have a fixed shape. You cannot squash or change the volume of solids. The particles are already as close to each other as they can get.]]> 2018-01-03 16:41:34 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218558606 Liquids pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218558832 With liquids, the particles are still very close. But the forces holding them together are not as strong as in solids. The particles can move around. This is why you can pour a liquid. You cannot squash a liquid because the particles are still very close together.]]> 2018-01-03 16:42:17 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218558832 Gases pinthus2005 https://padlet.com/pinthus2005/ngb920o5peh9/wish/218594128 The particles in a gas are a long way apart. They move around very quickly. Gases are easy to squash because there is a lot of space between the particles.]]> 2018-01-03 18:25:57 UTC https://padlet.com/pinthus2005/ngb920o5peh9/wish/218594128
