Specific Heat Capacity

• what is specific heat capacity?

  The amount of heat energy required to raise the temperature of 1kg of substance by 1 degree Celsius.
• units for specific heat capacity?

  J/kg degrees celsius
• an iron has an aluminium plate with a mass of 1.5kg. calculate thermal energy stored in the plate when the temp rises from 20 to 200. the shc of aluminium is 913 J/kg?

  200-20=180

  1.5x913x180= 246510J
• a hot water bottle cools down from 80 to 20 releasing 756000J of thermal energy. calculate the mass of the water in the hot water bottle. the shc of water is 4200 J/Kg degrees celsius?

  80-20=60

  m= thermal energy/shc x temp change

  m= 756000/4200 x 60 = 3kg
