Matter and Pressure KS3 Y8
- Solids
- Keep there shape and volume
- Atoms vibrate in fixed positions
- Keep there shape and volume
- Liquids
- Change shape, can flow
- Atoms move more free than solids
- Atoms move more free than solids
- Volume can't change
- Change shape, can flow
- Gases
- Can be compressed
- A fluid
- No fixed volume
- Can be compressed
- Evaporation
- Change of state
- Liquid to gas
- One particle on the surface on the water
- Gets a harder push
- Particles left behind have lost energy
- Get colder
- Get colder
- Gets a harder push
- Slow proccess
- Occur at different temperature
- Occur at different temperature
- One particle on the surface on the water
- Liquid to gas
- Change of state
- Boiling
- Quick proccess
- Can only occur at certain temperatures
- Quick proccess
- Expansion of solids
- Particles move further away from eachother
- Vibration and collision
- Metal gains volume
- Bends upwards
- Bends upwards
- Particles move further away from eachother
- Pressure
- Force/ Area
- P=F/A
- P=F/A
- More pressure on a smaller facet
- More pressure pushed on a certain area
- More pressure pushed on a certain area
- Larger area
- Less concentration
- Less concentration
- Force/ Area
- Pressure in liquids
- Depth*Gravitational pull*density
- P=h*g*p
- Pascal
- 1N/CM(2)
- 10000N/M(2)
- 1N/CM(2)
- P=h*g*p
- Depth*Gravitational pull*density
- Pressure in gases
- Collide with walls
- A force in each collision
- When compressed more collisions
- Less surface area
- Less surface area
- A force in each collision
- When it is heated
- Particles move quicker
- Collide more
- Collide more
- Particles move quicker
- Collide with walls
