Specific Heat Capacity

• What is specific heat capacity?

  Energy required to change state of 1 kg of a substance with no change in temp
• What equation is used to calculate the change in thermal energy?

  ΔE = m × c × ΔT
• How do you rearrange the equation to find mass?

  m = ΔE / (c × ΔT)
• What are the steps to calculate thermal energy change?

  1. Identify mass (m)
  2. Determine specific heat capacity (c)
  3. Calculate temperature change (ΔT)
  4. Use the equation: ΔE = m × c × ΔT
• What is the conversion from Joules to kilojoules?

  • Divide Joules by 1,000
• What is the significance of specific heat capacity in thermal energy calculations?

  • Determines energy needed for temperature changes
  • Varies by substance
