WHY does hot water have less mass than cold water?? Explain how temperature affects the mass of water

Hot water molecules are more spread out so not as many will fit into the same space/volume. Hot Cold

Viscosity: a liquid’s resistance to flowing Add to sentence box: *high viscosity = flows slowly, low viscosity = flows quickly Click on the picture below. Test different liquids, using the same temperature for both liquids. (You can change the temp., just change both of them to the same thing. Vocabulary!! (Add to your vocab. Paper)
