In physics we refer to how heavy the object is as the mass.
Fg = mass x acceleration due to gravity

It is to some sea creatures. Like the ones with air filled areas like lungs and swim bladders
Answer:
I believe it would be Pennsylvania and New Jersey they both border Maryland. Didn't see any other states that border Maryland with West Virginia and Virginia being exempt from the question.
Explanation:
You can look at magnesium, it can react with oxygen to form oxides. (chemical) it is malleable and a solid at room temperature. (physical)
to measure its density, the mass and volume can be worked out and from this density too. look up the equation, it is quite easy :)
physical changes -- it can be melted, and oxidized <span />
