Heather is investigating the properties of light and how it travels. She places a glass on the windowsill and waits for the sun to shine on the glass and observes what happens. Next, she places a piece of cardboard in front of the glass. Which statement describes the results of her observations?

A Since glass is translucent, most of the light energy was reflected from the glass.
B When the cardboard was placed in front of it, the cardboard absorbed some of the light energy.
C The light from the sun was able to travel through the glass. When the cardboard was placed in front of the glass, it absorbed the light energy from the sun and converted it into heat energy.
D The glass absorbed the light and converted the light energy into heat energy. When the cardboard was placed in front of the glass, the heat was transferred from the glass to the cardboard.
When the sun hit the glass, the light energy was absorbed. When the cardboard was placed in front of the glass, it absorbed the light energy from the sun and converted it into heat energy.

Why is rain likely when warm, moisture-laden air meets cold air? A) The lighter warm air will rise and cool down, causing condensation and rain. B) The cold air moves faster and pushes the warm air away, causing condensation and rain. Eliminate C) The moisture in the warm air condenses on contact with the cold air, causing rain to fall. D) The cold air mixes with the warm air, reducing its temperature causing moisture to condense.
