Question

It's cold outside and you decide to cook pasta. As you boil the noodles, the kitchen window begins to fog up.
Is this evaporation or condensation

Answer 1

The fogging up of the kitchen window is a result of condensation. When you boil pasta, the steam (water vapor) released from the boiling water rises and comes into contact with the cooler surface of the window. As the steam cools down, it changes back into liquid water, causing the window to fog up. In contrast, evaporation is the process of water turning into vapor, which occurs when the heat causes the water to turn into steam.
