Stephen placed a thermometer in a glass of ice water. He observed that the volume of the colored liquid inside the thermometer decreased. This happened because the molecules of liquid in the thermometer
moved slower and closer together when the liquid contracted.
were less attracted to each other because of electrostatic attraction.
changed the solid to a liquid.
moved from the thermometer into the ice water because the thermometer was warmer.
