BRAINCAKEParticle model of matter
Revision notes for Particle model of matter in AQA Combined Science: Trilogy (8464). Every lesson in BrainCake comes with R.E.C.I.P.E. recall steps, a quick check and spaced reviews.
- Density of materialsThe density of a material tells you how much mass is packed into a given volume.
- Changes of stateMatter changes state when its particles gain or lose enough energy to change how they are arranged.
- Internal energyEvery object is made of particles (atoms and molecules), and those particles store energy.
- Temperature changes in a system and specific heat capacityWhen a system is heated and its temperature rises, the size of the rise depends on three things: the mass of the substance heated, the type of…
- Changes of state and specific latent heatThe energy needed for a substance to change state is called latent heat.
- Particle motion in gasesThe molecules of a gas are in constant random motion.
