AQA GCSE Physics Topic 3 - Particle Model Of Matter

Below is everything the examiners think you know, if you're not sure of something click on the link to watch my YouTube video explanation. For a copy of these you can print off, get the FREE revision guide I wrote for you.

• I can describe the energy changes that happen when a substance changes state

• I can describe the energy in the atoms and molecules as internal energy

• I can explain that a change in the internal energy will lead to a change in temperature or a change in state

• I can define density

• I can recall the units needed for ρ = m/v

 I can rearrange ρ = m/v

 I can use ρ = m/v

• I can define specific heat capacity and specific latent heat

• I can recall the units needed for ΔE = mcΔθ

• I can rearrange ΔE = mcΔθ

• I can use ΔE = mcΔθ

• I can recall the units needed  for E = mL

• I can rearrange E = mL

• I can use E = mL

• I can describe the movement of particles in a gas

• I can relate the temperature of the gas to the average kinetic energy of the system

• I can explain how the motion of a gas relates to the pressure in a system

• I can relate the volume of a gas to the pressure -Physics only

• I can recall the units needed for pV = constant-Physics only

• I can rearrange pV = constant-Physics only

• I can use pV = constant-Physics only

• I can explain how doing work on a system can increase the temperature-Physics only
