When you open a an I've door to check on a cake that you are baking. A hot,moist air rushed out of the oven,his glass steamed up. This was due to

A.evaporation
B.freezing
C.melting
D.condensation

D. condensation

The correct answer is D. condensation.

When you open the oven door, you allow hot, moist air from inside the oven to come into contact with the cooler air outside. The steam that you see on the glass is formed when the hot, moist air comes into contact with the cooler surface of the glass. This causes the water vapor present in the air to condense into liquid water droplets, which is what makes the glass appear steamed up.

To arrive at this answer, we can eliminate options A, B, and C. Evaporation refers to the process of a liquid turning into a gas, which is not happening in this scenario. Freezing involves the transformation of a liquid into a solid, which also doesn't apply here. Melting refers to the process of a solid turning into a liquid, which is not relevant in this case either. Therefore, the explanation that best fits the situation is condensation.
