Ok here's my problem:
When I put a piece metal in a graduated cylinder filled with water to measure the metal's volume by "water displacement" I see air bubbles trapped under the metal. How do the air bubbles affect the density, mass and volume of the metal piece? Thanks. Need quick answer.
I was thinking that since air bubbles are light than the water, they would kind of like "float" and therefore push the metal piece upward. But I'm not sure if that affects the volume of the metal piece at all.
I was also thinking that since air do have volume, then it might contribute to an increase in the volume reading of the metal piece, and that without the air bubbles, the volume reading would be definite.
