Question

the baby chickens are kept warm from the heat lamps demonstrates this type of heat transfer. convection radiation conduction

Explanation:

Heat transfer by radiation occurs without a medium through electromagnetic waves. Heat lamps emit infrared radiation which warms the baby - chickens. Convection involves heat transfer through fluid motion and conduction requires direct contact. Since the heat from the lamp reaches the chickens without direct contact or fluid - mediated transfer, it is radiation.

Answer:

B. radiation
