Question: If two objects are in thermal contact, what will happen to their temperatures over time?

Options:

  1. They will remain the same
  2. They will equalize
  3. One will increase, the other will decrease
  4. They will both decrease

Correct Answer: They will equalize

Solution: 

According to the second law of thermodynamics, heat will flow from the hotter object to the cooler one until they reach thermal equilibrium.

Questions & Step-by-Step Solutions

If two objects are in thermal contact, what will happen to their temperatures over time?
  • Step 1: Identify the two objects that are in thermal contact.
  • Step 2: Determine the initial temperatures of both objects.
  • Step 3: Identify which object is hotter and which is cooler.
  • Step 4: Understand that heat will flow from the hotter object to the cooler object.
  • Step 5: Allow time for the heat transfer to occur.
  • Step 6: Continue the process until both objects reach the same temperature, known as thermal equilibrium.
  • Thermal Contact – When two objects are in thermal contact, they can exchange heat energy.
  • Second Law of Thermodynamics – Heat flows from a hotter object to a cooler one until thermal equilibrium is reached.
  • Thermal Equilibrium – A state where two objects reach the same temperature and no net heat flow occurs between them.
