When you use a microwave oven to increase the temperature of a cup of hot chocolate, which type of heat transfer is taking place?
Using electromagnetic waves
The electromagnetic radiation that passes through a microwave oven has a frequency in the microwave range (hundreds of megahertz). This radiation causes the polar water molecules in the food to oscillate at the same frequency, which causes the food to heat up.

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.
