1
The Specific Heat Capacity
How much energy it takes to raise the temperature for 1.0 g of a substance by 1° C is called the specific heat capacity We can find out how much energy is needed to change an objects temperature with this equation:
2
Q is bigger Effects of Mass on Heat Large object = mcΔT Smaller object
Q is smaller Think of boiling water for tea or cooking, more water means more time and energy Hot water tanks at home Conclusion: bigger objects need more energy to raise their temperature
3
Q is bigger Effect of SHC on Heat Large Specific Heat = mcΔT
Smaller Specific Heat = mcΔT Q is smaller 4.18 J/g·°C 0.32 J/g·°C Conclusion: bigger SHC need more energy to raise their temperature by the same amount
4
Effect of Temp Change on Heat
Large Temp Change = mcΔT Q is bigger Smaller Temp change = mcΔT Q is smaller Conclusion: bigger SHC need more energy to raise their temperature by the same amount
