What is conduction? - the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material., What is convection? - the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat., What is radiation? - radiation is the emission or transmission of energy in the form of waves, What are the three main types of heat transfer? - conduction, radiation, convection, When you touch your hand to a desk and the desk feels cold but then it gets warmer what process is this? - conduction, A radiator puts warm air out at the top and draws in cooler air at the bottom what process is this? - convection, A burning candle emits radiation in the form of heat and light what process is this? - radiation, How is visible light transferred from the fire? - The fire gives off visible light through radiation, What happens when kinetic energy increases? - Temperature also increases, What does a thermostat do? - Measures temperature,
