| buoyancy | to exert an upward force on an object immersed in the fluid |
| diffusion | spreading of particles until they dissolve completely |
| heat of fusion | amount of energy required to change a substance from solid phase tot he liquid phase |
| heat of vaporization | the amount of energy required for the liquid at its boiling point |
| kinetic theory | energy moving but depending on the mass |
| melting point | tempature at which a solid starts to liquify |
| pascal | SI unit of measure |
