9. From your PORE: Hot & Cold Water Part 1, explain why the red dye spread faster than the blue dye.
__________________________________________________________________________________________________
Choose the best answer:
Hot substances have (more/less) thermal energy, therefore the particles move (faster/slower).
Cooler substances have (more/less) thermal energy, therefore the particles move (faster/slower).
