Question

Maria touches a warm door with her cold hands. Which of the following statements identifies the type of energy transfer that occurs and the motion of the particles during the process?

A. Radiation; slow-moving particles in Maria’s skin collide with fast-moving particles in the door.
B. Conduction; fast-moving particles in Maria’s skin collide with slow-moving particles in the door.
C. Conduction; slow-moving particles in Maria’s skin collide with fast-moving particles in the door.
D. Radiation; fast-moving particles in Maria’s skin collide with slow-moving particles in the door

Answer 1

C. conduction is when two things are touching. the hand is warmer so it has faster moving particles

Answer 2

C

Radiation doesn't make sense.

And hot moves to cold, her skin particles weren't fast moving since it was cold.
