Final answer:
Food can be cooked by radiation, which refers to the emission of energy as electromagnetic waves or moving subatomic particles. Radiation can be used in cooking, such as in microwave ovens that use microwaves to heat food by exciting water molecules.
Step-by-step explanation:
Food can be cooked by radiation. Radiation is the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization. In the context of cooking, radiation can refer to electromagnetic radiation such as microwaves or infrared radiation that is used to heat and cook food. For example, microwaves use radiation in the form of microwaves to heat food by exciting water molecules within the food, generating heat and cooking the food.
