The mass of the rock will be greater than the total mass of the smaller pieces.
The mass of the rock will be less than the total mass of the smaller pieces.
The mass of the rock will be same as the total mass of the smaller pieces.
The mass of the rock will not be the same as the total mass of the smaller pieces.
A glass marble and a piece of cork of the same shape and size are dropped in water. Which of the following explains correctly why the glass marble sinks while the cork piece floats on water?
The glass marble is denser than water while the cork is less dense than water.
The glass marble is less dense than water while the cork is denser than water.
The glass marble and the cork are both denser than water.
The glass marble and the cork are both less dense than water.

Even though an iceberg and the water that surrounds it are made up of the same substance, the iceberg is able to float. Why is the iceberg able to float?
The volume of the iceberg equals the volume of an equal mass of water.
The mass of the iceberg is greater than the mass of an equal volume of water.
The iceberg is less dense than liquid water so it floats.
The mass of the iceberg is less than the mass of an equal volume of water.

Will the types of wood float?
Yes they will float because they are less dense than water.
No, they will sink because they are much heavier water.

If you needed to find the volume of a rectangular shaped prism, what procedure would be the best to follow?
use a ruler to measure length x width x height
use a graduated cylinder, fill it with water to a specified amount, drop the object in and subtract the difference between the heights.
use an electronic balance, set the units that you want and put it on the balance.
None of the instruments and procedures will do
One balloon is filled with helium and the other is filled with air. The gas inside the balloons each takes up the same amount of space and the difference in mass is only a few grams at most. Why might the helium balloon float and the other balloon rest on the table?
helium has less mass in the same amount of space than air does, so, the helium balloon sinks in air.
helium has less mass in the same amount of space than air does, so, the helium balloon floats in air.
air has less mass in the same amount of space than helium does, so the helium balloon sinks in the air.
helium has more mass in the same amount of space as air and sinks,
