Worked Solution & Example Answer:Name two methods by which heat can be transferred. - Leaving Cert Physics - Question d - 2007
Step 1
Conduction
Answer
Conduction is the transfer of heat through a material without any movement of the material itself. It occurs when there is a temperature difference within the material, leading to the transfer of kinetic energy from the faster-moving (hotter) particles to slower-moving (cooler) particles.
Step 2
Convection
Answer
Convection is the transfer of heat in fluids (liquids and gases) due to the movement of the fluid itself. Warmer, less dense regions of the fluid rise, while cooler, denser regions sink. This process creates a circulation pattern that helps to transfer heat throughout the fluid.
