1. What is the formula for specific heat capacity?

  • Change in temperature = mass / specific heat capacity x energy
  • Energy = mass x specific heat capacity x change in temperature
  • Energy = mass / specific heat capacity / weight
  • Specific heat capacity = energy x mass x change in temperature
