Equilibrium temperature: 74.19 °C

  • 24304 J of heat was transferred from the hotter object to the cooler one.
  • Object 2 has a larger thermal capacity, so it changed temperature less than object 1.
  • The equilibrium temperature (74.19 °C) sits off-center because the two objects have different thermal capacities.

Next stepThis calculation assumes no heat is lost to the environment (perfectly insulated system). In practice, insulation losses will lower the true equilibrium temperature.
