Question | Answer |
---|---|
kinetic energy | energy in the form of motion; depends on the mass of velocity of the object |
melting point | temperature at which a solid begins to liquefy |
heat of fusion | amount of energy required to change a substance from the solid phase to the liquid phase |
heat of vaporization | amount of energy required for liquid particles to escape the attractive forces within the liquid or the energy or the energy required to change from a liquid to a gas |
boiling point | temperature at which the pressure of the atmosphere is equal to the pressure of a liquid's vapor, and a gas molecules can escape the attractive force between the molecules |
diffusion | spreading of particles throughout a given volume until they are uniformly distributed |
plasma | high temperature gas with an overall neutral charge that is most common state of matter in the universe |
thermal expansion | increase in the size of a substance that results of from the separation of its molecules when the temperature is increased |
