Heat Energy Transfer GCSE Physics

Textbook reference CCEA Physics, Page 17 – 25 Key words list, what do you think the words and phrases mean? You don’t want to get confused… like President Bush!

Learning Intentions State the three types of heat energy transfer Recall in detail how the three types of heat energy transfer occur.

Don’t let the cold in!!!

Heat Transfer Heat Flow Objects get hot if heat energy (thermal energy) passes into them. We know they get hot because the temperature rises. It is important that we know the difference between temperature and heat: Temperature - the measure of how hot something is, measured in degrees Celsius; Heat - a flow of energy from a hot object to a cold object. Heat is measured in joules (J).

Particle motion in a substance

Heat Flow Heat always flows from hot to cold. Heat does not flow from a cold object to a hot object. For example the heat from a hotplate passes into a cold pan to heat up the water in the pan. The greater the temperature difference between the hot object and the cold object, the greater is the flow of heat. HOT HEAT COLD

Types of Heat Energy Transfer Page 17 TThe three ways in which heat can move (types of heat energy transfer) are… Conduction Convection Radiation

Convection

10 Which weighs more?

Convection Structure of a Liquid and a Gas Both states of matter flow and carry the heat energy with them.

Particles move feely Gain heat energy Move faster and spread out Volume becomes less dense Rises and bringing the heat energy What causes the convection currents?

 The movement of hotter areas in a liquid can be seen using potassium permanganate as a dye: H E A T This cycle is called a convection current.  Can you explain how the convection current moves using the idea of density? The diagrams on the left will help you. Change in Density
