Heat is Transferred 3 Ways Convection the transfer
- Slides: 11
Heat is Transferred 3 Ways • Convection –the transfer of thermal energy by movement of currents within a gas or a liquid E. g. Air and ocean current, boiling water • Radiation – transfer of energy by electromagnetic waves E. g. Roasting marshmallows over a fire – the transfer of thermal energy between particles within a substance by touch • Conduction E. g. Getting a burn from picking up a hot pot on the stove
HEAT TRANSFER SCENES Physical Sciences Can you identify which type of heat transfer is occurring?
Ben’s breath on a cold day Convection –The Ben’s breath is circulating in the air
Hot cocoa Convection –The heat in the hot cocoa is travelling in a current in the cup Conduction –When your hand touches the cup
Soup spoon in hot soup Conduction –Heat transferred from soup to spoon through direct contact
A geyser named Geysirs -a hot spring that releases water and hot steam out of the Earth’s surface Convection –Hot steam and water are circulating under and above ground in currents
Chicks huddling under a heat lamp Radiation –Heat is being transferred by electromagnetic waves (Light energy) via the heat lamp
Baking chocolate cake Convection –Heat in the oven circulates in currents to bake the cake Conduction –The woman is transferring heat to her oven mitts
Melting ice cream Conduction –Heat is being transferred from the hand to the ice cream cone causing the ice cream to melt
Fireplace Radiation –The room is being heated through electromagnetic waves (light energy)
Boiling water Convection –The heat is circulating in a current through the boiling water Conduction –Heat is being transferred through touch from the hot water directly to the eggs
