Question

Alana drew diagrams to show how particles in a spoon move before and after the spoon is placed in hot liquid.

At left a grid labeled Before of regularly arranged orange balls with large movement lines near each. At right a grid labeled After of regularly arranged orange balls with small movement lines near each.

Which best explains how to correct Alana’s error?

Make the particles in both diagrams larger.
Show more movement in the “Before” diagram.
Add more particles to the “After” diagram.
Switch the labels on the diagrams.

Answer 1

Switch the labels on the diagrams.

Reason: placing the spoon in hot liquid increases particle motion (larger movement lines). The diagram with large movement lines should be labeled After, and the one with small movement lines Before.
