± Using Microwave Radiation to Heat Coffee Microwave ovens use microwave radiation to heat food. The microwaves are absorbed by the water molecules in the food, which is transferred to other components of the food. As the water becomes hotter, so does the food.

Approximately 80% of infrared (IR) radiation emitted by Earth is trapped by greenhouse gases, causing the warming of Earth\'s atmosphere known as the greenhouse effect. Even though nitrogen (N2) and oxygen (O2) make up the majority of the atmosphere (~99%), they do not contribute to the greenhouse effect. However, carbon dioxide (CO2) is a major contributor. Why does CO2 contribute to the greenhouse effect, while N2 and O2 do not? CO2 absorbs ultraviolet radiation escaping from the Earth\'s surface, creating...

1. Microwave ovens work by irradiating food with microwave radiation. Microwaves are absorbed by polar molecules (mostly water) and physically rotate. The increased rotation is an increase in kinetic energy which increases the temperature of the food. a.)
