Specific Heat Capacity
Define Specific Heat Capacity
Yes! Specific heat capacity is back! No, this is not a mistake - specific heat capacity appears twice in the specification! So here goes!
Specific Heat Capacity Equation
Sometimes E is also written as Q.
List of different substances and their specific heat capacities (J/kg°C)
- Water = 4200
- Air = 990
- Copper = 390
- Iron = 450
- Concrete = 3400
- Cotton = 1400
- Using the list, how much energy has been put into 10kg of cotton for the temperature to rise by 20oC?
- Your answer should include: 280kJ / 280 kJ / 280000J / 280000 J
- For the same amount of mass, which requires more energy to raise the temperature by 15oC, water or concrete?
- water
- Calculate the mass of iron, when it takes 50kJ of energy to raise the temperature by 300 degrees C?
- Your answer should include: 0.37kg / 370g
- Using the table, how much energy has been put into 10kg of cotton for the temperature to rise by 20 degrees C?
- Your answer should include: 280kJ / 280000J / 280000 J / 280 kJ
