Science Assessment ~ Topics ~ Atoms, Molecules, and States of Matter ~ Misconception AMM091

The mass of the atoms or molecules of a substance increases when the temperature decreases and decreases when the temperature increases (Herrmann-Abell & DeBoer, 2007, 2008).

Items that test for misconception AMM091 in this project (Original Project) and key idea (For any single state of matter, inc…)
Item ID Number	Item Description	How Often the Misconception was Chosen
AM049003	The distance between water molecules increases when a cup of cold water warms up to room temperature.	19%
AM073002	The molecules of hot air are farther apart than the molecules of cold air.	18%
AM045004	The molecules of cold water are closer together than the molecules of hot water.	17%
AM039004	The distance between water molecules increases as a cup of water is warmed.	17%
AM052003	When an iron frying pan cools, the distance between the iron atoms decreases, so the pan gets a tiny bit smaller.	16%
