c1 - energy

• energy cannot be created or destroyed
• specific latent heat is the energy required to change the state of ing of a material, without changing its temperature
• specific heat capacity is the amount of energy required to raise the temperature of 1kg of material by 1 ℃
• Energy stores :

  Kinetic

  Gravitational

  Chemical

  Elastic potential

  Magnetic

  Electrostatic

  Nuclear

  Thermal
• Internal energy is the energy stored by the particles that make up on object
• The law of conservation of energy states that energy cannot be created or destroyed
• Work done = force x distance
• energy = voltage x current x time
• Power = work done / time
• how can you prevent unwanted energy transfers in homes?

  have thicker walls, fit loft insulation, use double glazing
