Question

you removed a coke can from the refrigerator. when you come back a few minutes later, you realize the can has begun to sweat. in other words, moisture forms on the outside of the can. select all of the statements that describe the formation of condensation on the can.
a water vapor in the air gains energy, causing it to form condensation on the can.
b as water molecules in the air come in contact with the cold can, they will slow down.
c as water molecules in the warm air collide with the cold can, they will lose energy and become colder.
d vapor molecules in the air are attracted to water molecules on the can, causing them to bind to the can.

Explanation:

Condensation occurs when warm, moist air comes in contact with a cold surface. Water molecules in the warm air slow down and lose energy upon collision with the cold can. Water vapor in the air doesn't gain energy to form condensation (it loses energy). There is no significant attraction - based binding as described in option D.

Answer:

B. As water molecules in the air come in contact with the cold can, they will slow down.
C. As water molecules in the warm air collide with the cold can, they will lose energy and become colder.
