In the Classroom

Pre-Experience (Things to Look Out For):

• Do you know what evaporation is? Try to define it in your own terms.

• How do you think it might be different from vaporization/boiling?

• What are some real-world examples of evaporation you’ve seen?

Post-Experience (Things to Think About):

• Can you name a few scenarios where evaporation is essential?

• Other than molecular speeds, what are the factors that can potentially affect evaporation?

• Is there a temperature threshold for evaporation to happen?

• When we get hot, we sweat, and our skin eventually dries due to evaporation. Why does this happen? What purpose does sweating serve? (Hint: it has to do with a heat-transfer that occurs as part of evaporation)
