What could make two thermometers (A and B) have the same temperature but the red liquid is higher in thermometer A than in thermometer B.
The liquid inside the thermometer

If molecules are moving quickly in warm water (not at the boiling point), what is stopping the molecules from moving very far apart and becoming a gas
The attraction of the water molecules to each other
300
What are the two PROPERTIES of matter?
All matter has mass and volume (takes up space)
300
An increase in temperature increases the motion of molecules and the distance between them in which state(s) of matter.
Solid, liquid and gas

What happens if you put a drop of blue and yellow food coloring in two cups of water. One is hot, the other is cold. Why does this happen.
They will both eventually turn green but it will spread and combine faster in the hot water because the molecules are moving faster.

Miss Miller was doing an experiment. She has a metal ball and a ring it barely fits through. She wants to weld them together into a sculpture. She heats up the metal ball, tries to put it through the metal ring and it no longer fits! Why?
The molecules are moving faster and slightly spreading out
