- 1Physics 4Simple kinetic molecular model of matter
- 2Kinetic molecular modelKinetic molecular theory explains the forces between molecules and the energy they possess
3 basic assumptions - 33 basic assumptions- All matters are composed of small particles (atoms&molecules)
- Particles are in constant motion
(Different in 3 matters) (When particles collide with other or wall, energy is not lost)
- With increasing temperature, particles vibrate faster and more strongly as they gain kinetic energy (leads to increased collision rate, collision energy) - 4Particles in solidParticles held closely together by attractive forces
Will/can bend/vibrate, but will stay in close proximity - 5Particles in liquidParticles will glide or flow over each other, but will stay towards bottom of container
Motion is more random than solid - 6Particles in gasesParticles are in continual straightness motion
KE is stronger than attractive force between particles, particles are farther apart and move more freely - 7Properties of solids
- 8Peoperties od liquids

- 14Particles model of liquid 2
- 15Particles model of liquid 3
- 16Diffusion... Confusion
- 17Evidence for random movement of particles in liquid
- 18Evidence for random movement of particles in liquid 2 (Brownian motion)
- 19Brownian motion
- 20Particle model - gas
- 21Particle model - gas 2
- 22Temperature and motion
- 23Pressure and motion
- 24Temperature and pressure at constant volume
- 25The physical properties of 3 states
- 26The physical properties of 3 states
- 27Evaporation and condensation
- 28Evaporation and heating
- 29Evaporation and cooling
- 30Latent heat of vaporization
- 31just wat is this
- 32Temperature and evaporation
- 33Surface area and evaporation
- 34Flow rate of air and evaporation
- 35yaaaasRelate the change in volume of a gas to
change in pressure applied to the gas at
constant temperature and use the equation
pV = constant at constant temperature. - 36Boyle's law
- 37Boyle's law
- 38Physics 6Transfer of thermal energy
- 39Insulators and conductorsHeat energy can move through a substance by conduction
Metals are good conductors of heat, but non-metals and gases aren't so much
Poor conductors of heat is known as insulators
From hot end to cold end - 40Good and bad conductors of heat
- 41Comparing the thermal conductivities of different materialsMetal rods of different types e.g. copper, brass and iron may be used to compare the conductivity of different metals
- 42Comparing the thermal conductivities of different materials
- 43Comparing the thermal conductivities of different materialsHeat is conducted faster through a rod if it
has large cross-section area, is short and as a large temperature difference between its ends - 44Heat transfer and molecular motion
- 45—
- 46—
- 47Convection in fluidLiquid and gases are fluid
Particles in fluids can move from place to place
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy.
Heat energy is transferred from hot places to cold places by convection - 48Convection in liquids
- 49Convection in liquids 2
- 50—As hot water above candle rises it pushes the dye round the apparatus
- 51Convection in gases
- 52Can use smoke to see it
- 53FluidsA continuous, amorphous substance whose molecules move freely past one another and that has the tendency to assume the shape of its container; a liquid or gas
- 54Convection in fluids
- 55Convection in fluids 2
- 56RadiationRecognise radiation as the method of heat
transfer that does not require a medium to travel through.
Identify infra-red radiation as the part of the electromagnetic spectrum often involved in heat transfer by radiation. - 57Radiation
- 58welp here comes hard stuuf
