  4. None of the above

Questions & Step-by-Step Solutions

In which of the following processes does heat transfer occur without any medium?
  • Step 1: Understand what heat transfer means. Heat transfer is how heat moves from one place to another.
  • Step 2: Learn about the three main ways heat can transfer: conduction, convection, and radiation.
  • Step 3: Identify conduction. Conduction is heat transfer through direct contact between materials, so it needs a medium (like metal).
  • Step 4: Identify convection. Convection is heat transfer through fluids (liquids or gases) and also needs a medium (like air or water).
  • Step 5: Identify radiation. Radiation is heat transfer through electromagnetic waves and does not need a medium (it can happen in a vacuum).
  • Step 6: Conclude that radiation is the only process listed that allows heat transfer without any medium.
