Use the descriptions of two different experiments to answer the next three questions:
Experiment X Experiment Y
Students find the mass of a test tube of Students mass an empty balloon, filled it
water, a fizzing tablet and a beaker. They with a gas and massed it again. They
add the tablet to the water, it bubbles and measured its volume by placing it in a full
they collect the gas in a graduated cylinder. container of water that overflows. They
They mass the water and the beaker again collected the overflow and find the volume
and subtract this mass from the first. They the balloon displaced. They find the mass
divide the change in mass by the volume of by subtracting the mass of the balloon
gas they collected in the graduated cylinder. empty from it’s mass when it is full of gas.
Then they divide the mass by the volume.

Essay
3. If the clean up begins immediately, how is the density of the oil an advantage for the clean
up crew?
4. The oil in a spill with combine with water in a few days and sink to the bottom. How has
the water affected the density of the oil?
2. Because marine mammals and birds live on the surface, they are more likely
be damaged than fish swimming underneath. Marine birds are also at greater
risk of harm than fish because they land and float on the surface.
3. Because the oil that floats on water is much easier to clean up than if it were
to sink to the bottom.
