All cooking methods have one thing in common:
heat
A method of transferring heat by direct contact
Conduction
a method of transferring heat as waves of energy.
Radiation
a method of transferring heat through the movement of molecules in air or liquid.
Convection
What affects food while it is cooking?
Density, Amount, Shape and Size.
In Conduction, heat moves from ________________________________
heat moves from one object to another object
Radiant heat floes evenly from the source __________, unlike which process?
in every direction. Unlike convection.
What kind of air rises? And as it rises it pushes what kind of air down?
Warm air rises, while it rises cool air is pushed out the way creating a convection current.
True or False: Cooking methods can use a combination of heat-transfer processes.
True
Give a example of conduction:
Pancake in a skillet
Give an example of Radiation:
Sun warms the earth
flames on a broiler
Besides air, How does convection also occur?
In liquids
What is the Milliard reaction?
Browning occurs when heat provokes a series of chemical reaction between certain sugars and proteins in the food.
How does a heated molecule pass heat to an unheated molecule?
conduction= heavy heat
What is the difference between convection and radiation?
The heat waves and direction
What keeps convection currents moving?
Currents for cooking (rely on the constant cyclical motion of air, water and other substances to distribute heat).
