Amy was sitting outside on a hot, summer day, enjoying a glass of sweet iced tea. She notices some water droplets on the outside of her glass.  What is causing those water droplets?

• The outside air is heating up the ice, causing it to melt into a liquid.

• The cold liquid in the glass is cooling the air around it, making it condense into a liquid.

• The outside air is heating up the liquid in the glass, causing it to evaporate.

• The liquid in the glass is cooling the air around it, causing it to evaporate.

When you boil water in a pot, some of the water escapes as steam. Which of the following choices explains what is happening with the water molecules in this scenario?

• The molecules slow down as the kinetic energy increases and move farther apart from one another.

• The molecules slow down as the kinetic energy decreases and move closer together.

• The molecules speed up as the kinetic energy increases and the molecules move farther apart from one another.

• The molecules speed up as the kinetic energy decreases and the molecules move closer together.
