Convection, Conduction, and Radiation

Conduction The process which heat or electricity is directly transferred through a substance when there is a difference in temperature or electrical potential. Conduction = TOUCHING

Convection The movement caused within a fluid where the hotter, less dense material rises. Heat Rises Cold Sinks

Radiation Requires no substance to travel from one place to another. It can move through space. Energy moves away from the hotter object

Describe the heat transfer in the picture below. The heat is being transferred from the hot soup bowl to the spoon by conduction.

Describe the heat transfer in the wind, the Earth’s oceans, and the Earth’s mantle. Wind – when heat rises and cool air falls, wind is created Oceans – when warm water rises and cools, currents are created. A second factor is wind. Mantle – when hot magma rises and cool magma/rock falls, it causes the tectonic plates to move. All are examples of convection currents.

Describe how sunburns are related to heat transfer. Sunburns are caused from the radiant energy from the sun. The energy is released by the sun in the form of electromagnetic waves and can cause sunburns on Earth.
