Two beakers are filled with the same amount of fluid. One is filled with regular water and the other is filled with salt water. Both start at 67 degrees Fahrenheit. The regular water heats up to 70 degrees but the saltwater heats up to 73 degrees. What does the difference in ending temperatures tell you about the difference between regular and saltwater?

• Salt water absorbs more of the sun’s energy than freshwater.

• Freshwater absorbs more of the sun’s energy than salt water.

• Only salt water absorbs the sun’s energy.

• Only freshwater absorbs the sun’s energy.

Which section of the electromagnetic spectrum is the only one humans can see?

• visible light

• radio waves

• gamma rays

• ultraviolet rays

Why does light separate into colors when passing through a prism?

• Each color has a slightly different wavelength and passes through the prism at a different angle.

• The prism absorbs the white light, but allows the colors to pass through.

• When the light is reflected in the prism, a rainbow is reflected back.

• The white light is destroyed as it passes through the prism.
