A guess/prediction
Anything that has mass and takes up space
Matter
the smallest unit of the element that maintains the properties of that element
atom
water vapor, oxygen, air
examples of gases
the change of state from a liquid to a gas that usually occurs at the surface of the liquid
evaporation
The factor that stays the same
Constant
Mass
made of one or more of the same kind of atom
element
