  • P1 - Energy For The Home
    • Moving And Storing Heat
      • When substance is heated gains kinetic energy
      • Measured on an absolute scale
      • The unit of heat is joules (J)
      • Temperature normally measured in °C
      • Specific heat capacity can tell you home much you have stored
        • Specific heat capacity is the amount of energy needed to raise the temperature of 1 kg of a substance by 1 °C.
        • materials that need to gain a lot of energy warm  up also release a lot of energy when they cool down again. they can "store" a lot of heat
