Weather & Climate Quiz #2

In the "Density of Fluids Lab", why did the red water float on the top of the vial?

• Because it was hot and therefore denser than the other layers.

• Because it was cold and therefore denser than the other layers.

• Because it was hot and therefore less dense than the other layers.

• Because it was the same density as the other layers.

In the "Density of Fluids Lab", why did the blue water sink to the bottom of the vial?

• Because it was hot and therefore less dense than the other layers.

• Because it was cold and therefore denser than the other layers.

• Because it was cold and therefore less dense than the other layers.

• Because it was the same density as the other layers.

In the "Density of Fluids Lab", why did the clear water stay suspended in the middle of the vial?

• Because it was room temperature and therefore less dense than the cold water, but denser than the hot water.

• Because it was the same density as the other layers.

• Because it was room temperature and therefore denser than the cold water, but less dense than the hot water.

Over time, the layers will mix and the color of the water will become purple because...

• the temperatures of the layers will all become room temperature.

• the densities of the layers will all become the same.

• Both the temperatures and the densities of the layers will become the same.
