Identify the type of energy transferred to your body in each of the following as either internal energy, heat transfer, or doing work: (a) basking in sunlight; (b) eating food; (c) riding an elevator to a higher floor.
Basking in Sunlight: During basking in sunlight, heat of Sun gets transfers in the body. So here energy transfer is the Heat transfer.
Eating Food: Eating food gives us energy which is store in our body as internal energy. So here energy transfer is as Internal energy
Riding an elevator to a higher floor: When moving upward work is done against gravity to increase potential energy. So here heat transfer is Work done
