| Question | Answer |
| Energy added can do two things. What are they? | 1. increase kinetic energy 2. break/make bonds |
| potential energy = | = intermolecular forces |
| What is latent heat? | the energy needed for a substance to change its state and break its bonds, without changing the temperature |
| define specific latent heat | the amount of energy required to melt/boil 1kg of a substance without changing its temperature |
| What is the formula for latent heat? | specific latent heat = energy / mass |
| The amount of energy required to change the state of a sample depends on what? | 1. the substance 2. the state change 3. the mass |
| define specific latent heat of fusion | the energy needed to change the state of 1kg of a substance from solid to liquid |
| define specific latent heat of vaporisation | the energy needed to change the state of 1kg of a substance from liquid to gas |
