CP12 Particle Model CP12a Particles and density Step Learning outcome Had a look Nearly there Nailed it! Describe the arrangements of particles in solids, liquids and gases. Use the particle model to explain the different properties of solids, liquids and gases. Recall the formula relating density, mass and volume. Use the formula relating density, mass and volume. Use the particle model to explain why solids, liquids and gases have different densities. Describe what happens to the mass of a substance when it changes state. Energy and changes of state Step Learning outcome Had a look Nearly there Nailed it! Explain how heating affects the particles in a substance or object, including changes of state. Describe how the temperature of an object changes with time while being heated or cooled to make it change state. Define the term specific heat capacity. Define the term specific latent heat. Explain the difference between specific heat capacity and specific latent heat. Explain ways of reducing unwanted energy transfer through thermal insulation. CP12c Energy calculations Step Learning outcome Had a look Nearly there Nailed it! Use the formula relating change in thermal energy, mass, temperature change and specific heat capacity. Use the formula relating thermal energy, mass and specific latent heat. Recall that the value of specific latent heat for a substance is different for melting/solidifying and for evaporating/condensing.
