Sublimation
matter that contains energy to overcome attractive forces within it’s atoms, with positively & negatively changed particles
Plasma
increase of the volume of the substance when the temperature increased
Thermal expansion
fluid’s ability to exert an upward force on an object immersed in it
Buoyancy
amount of force exerted per unit area, SI unit is pascal(Pa)
Pressure
the speed and direction of a moving object
Velocity
states that the volume & pressure of a gas are related
