Flashcards
Conduction
Conduction
The transfer of heat through a solid material by direct contact. Think of a metal spoon heating up in a hot bowl of soup.
Convection
Convection
The transfer of heat through a fluid (liquid or gas) via the movement of currents. Boiling water is a good example.
Radiation
Radiation
The transfer of heat through electromagnetic waves. Think of the sun warming the earth or a broiler cooking food.

Study Notes
Heat Transfer
- Heat transfer involves the movement of thermal energy from one place to another due to temperature differences.
- Conduction is heat transfer through direct contact, like a pan on a stove.
- Convection is heat transfer through the movement of fluids (liquids or gases), such as boiling water.
- Radiation is heat transfer through electromagnetic waves, like heat from a broiler.
- In cooking, understanding heat transfer is essential for even cooking and browning.
Cooking Methods
- Dry-heat cooking methods use air or fat, like roasting, grilling, and frying.
- Moist-heat cooking methods use water or steam, like boiling, steaming, and poaching.
- Combination cooking methods use both dry and moist heat, like braising and stewing.
- Sautéing involves cooking food quickly in a small amount of fat over relatively high heat.
- Sous vide is a cooking method where food is sealed in a bag and cooked in a water bath at a precise temperature.
Phase Changes
- Phase changes involve the transition of matter from one state (solid, liquid, gas) to another.
- Melting is the phase change from solid to liquid, like ice melting into water.
- Boiling/Evaporation is the phase change from liquid to gas, like water boiling into steam.
- Freezing is the phase change from liquid to solid, like water freezing into ice.
- Condensation is the phase change from gas to liquid, like steam condensing on a cold surface.
- Sublimation is the phase change from solid to gas, skipping the liquid phase, like dry ice sublimating into carbon dioxide gas.
Matter
- Matter is anything that has mass and takes up space.
- The three common states of matter are solid, liquid, and gas.
- Solids have a fixed shape and volume.
- Liquids have a fixed volume but take the shape of their container.
- Gases have neither a fixed shape nor a fixed volume and can be compressed.
- Plasma is another state of matter consisting of ionized gas and is less relevant in culinary contexts.
