If you touched a hot ceramic coffee mug with your bare hands, this would be an example of what type of heat transfer?

When you touch a hot ceramic coffee mug with your bare hands, the heat you feel is transferred through direct contact. This process is known as conduction, which is the transfer of heat through a solid material or between materials that are in direct contact with each other. In this case, the heat moves from the hot mug to your cooler skin, causing you to feel warmth.

Other types of heat transfer, such as radiation and convection, do not apply here. Radiation involves heat transfer through electromagnetic waves, like the warmth you feel from the sun. Convection refers to heat transfer through fluids (liquids or gases) due to the movement of the fluid itself, often seen in boiling water. Since touching the mug involves no fluid movement or wave radiation, it firmly falls under the category of conduction.
