Particle model and the three states 0.0 / 5 ? ChemistryParticlesGCSEOCR Created by: emilysworldCreated on: 30-04-19 08:42 What does the particle model not take into account? Forces of attraction between particles, the size of particles, and the space between them 1 of 29 What are intermolecular forces of attraction? The likelihood mof particles being attracted. How much they are attracted to each other 2 of 29 What happens when a gas turns to a liquid? Heat energy decreases so less kinetic energy so the particles can no longer overcome IMFA so they get closer together and move in contact 3 of 29 What is room temperature? 25C 4 of 29 What is viscosity? how thick something is 5 of 29 What is the shape of a solid? hold their own shape 6 of 29 What is the shape of a liquid? take shape of bottom of container 7 of 29 What is the shape of a gas? take as much space as is available 8 of 29 Is there flow/movent in a solid? no 9 of 29 Is there flow/movement in a liquid? Yes 10 of 29 Is there flow/movement in a gas? yes 11 of 29 Do solids diffuse? No 12 of 29 Do liquids diffuse? Yes - move around each other 13 of 29 Do gases diffuse? Yes - fast movement in all directions 14 of 29 Are solids compressible? no 15 of 29 Are liquids compressible? a tiny bit 16 of 29 Are gases compressible? Yes 17 of 29 What is the particle arrangment of a solid? uniform 18 of 29 What is the particle arrangment of a liquid? random 19 of 29 What is the particle arrangment of a gas? random 20 of 29 What is the particle spacing of a solid? touching 21 of 29 What is the particle spacing of a liquid? touching 22 of 29 What is the particle spacing of a gas? far apart 23 of 29 What is the kinetic energy of a solid in comparison to the other states? lowest 24 of 29 What is the kinetic energy of a liquid in comparison to the other states? in between 25 of 29 What is the kinetic energy of a gas in comparison to the other states? highest 26 of 29 What is the IMFA of a solid in comparison to the other states? highest 27 of 29 What is the IMFA of a liquid in comparison to the other states? in between 28 of 29 What is the IMFA of a gas in comparison to the other states? lowest 29 of 29
