Question

Quizplus · Accepted Answer

Water molecules have a dipole moment that makes them able to absorb electromagnetic radiation in the infrared region. This absorption causes water molecules to vibrate and thus the water heats up. This is the principle behind microwave ovens, which use electromagnetic radiation in the microwave region (also absorbed by water) to heat up food containing water.
