How does heat transfer when you hold an ice cube in your hand?

• from the cold ice cube to your warm hand

• the cold ice cube makes your hand cold

• from your warm hand to the cold ice cube

• very carefully

Although you may not be able to observe the particles in matter moving, how can you detect the motion?

• by the material’s weight

• by how warm or cool a material is

• by the way the material moves up and down slightly

• by the material’s vibration as it goes through your hands
