chemical property
a property of matter that describes a substance based on its ability to change into a new substance with different properties
physical property
a property of matter that can be observed to measured without changing the identity of the matter
matter
anything that has volume and mass
meniscus
the curve at a liquids surface by which you measure the volume of a liquid
