FOOD TECHNOLOGY

Detailed explanation-1: -Conduction and convection are the two methods commonly used in cooking. When boiling a potato, heat is transferred from the cooker to the cooking utensil (solid), the cooking utensil will heat up water (liquid) inside it, and lastly heat will be transferred to molecules in the potato.

Detailed explanation-2: -Convection is one of five heat transfer methods commonly used in cooking, including conduction, boiling, condensation, melting, and radiation. Convection is the process by which food is heated by a moving heat source, such as the hot air in an oven, or even the motion of boiling water in a pot.

Detailed explanation-3: -Examples of Convection Cooking Water coming to a boil and circulating in the pot. Running cold water over frozen food, which transfers heat into the food to thaw it more quickly. Room temperature air moving around frozen food to thaw it.
