Specific heat capacity

• Specific heat capacity


  The amount of energy required to raise the temperature of one kilogram of a substance by one degree Celsius
• Calculating energy required to increase temperature

  1. Mass in kg

  2. Specific heat capacity in J/kg/°C

  3. Temperature change in °C
• The change in thermal energy = mass x specific heat capacity x temperature change
• 672 kJ of energy is required to increase 2 kg of water from 20°C to 100°C
• 246.51 kJ of thermal energy is stored in the 1.5 kg aluminium plate when heated from 20°C to 200°C
• The mass of water in the hot water bottle is 3 kg
