What is the type of energy transferred to my body in each of the following as either internal energy, heat transfer, or doing work, when i am basking in sunlight, eating food and riding an elevator to a higher floor?
Isabella AlvarezI would attempt the following: eating food = internal energy (energy your cells obtain by transforming food through chemical reactions); riding an elevator = working (against gravity to increase potential energy); and, finally, basking in sunlight = heat transfer (through radiative transfer from a hot body to a cold one).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
