What are the 5 reasons to cook food | to enhance flavour, to preserve food for longer, to make sure it's safe to consume, to enhance texture, to vary a diet |
what are the 3 methods of heat transfer | conduction, convection, radiation |
describe convection (3 points) | heat transfer through liquid and gas where warmer liquid rise and cooler liquid sinks, movement of water creates convection currents. |
give an example where convection takes place | oven |
describe radiation (2 points) | heat transfer through radiation waves where food absorbs and heats up |
Give 3 examples where radiation takes place | microwave, toaster, grills |
describe conduction (3 points) | transfer through vibrating particles where when heat transfers particles vibrate and transfer heat energy to food |
give 1 example where conduction occurs | pan |
