Miguel prepares a flower bed on a hot summer morning. He covers the bed with a sheet of plastic that extends to the edge of the bed. He notices at the end of the day that the plastic now extends two inches beyond the edge. Why has that happened?
a) because the weight of the air caused the plastic to expand
b) because the heat of the sun caused the plastic to expand
c) because the lower air pressure caused the plastic to expand
d) because the higher air pressure caused the plastic to expand

Which statement best explains how energy is transferred during evaporation and precipitation?
a) Liquid water loses energy during evaporation and then loses more energy during precipitation.
b) Liquid water absorbs energy from the sun during evaporation and then loses energy, forming precipitation.
c) Liquid water loses energy during evaporation and then absorbs energy from the sun, forming precipitation.
d) Liquid water absorbs energy from the sun during evaporation and then absorbs more energy from clouds during precipitation.

Which statement best describes what will occur when a hot nail is dropped into a container of cold water?
a) Heat energy in the cold water will flow into the nail.
b) Heat energy in the nail will flow into the cold water.
c) The cold water will prevent the nail from losing heat.
d) The hot nail will remain warmer than the cold water.

A builder measures the length of a metal beam and finds that it is slightly shorter than when he measured it that morning. Why is the beam shorter?
a) The temperature increased, causing the beam to expand.
b) The temperature decreased, causing the beam to contract.
c) The beam’s mass decreased, causing the beam to expand.
d) The beam’s mass increased, causing the beam to contract.

Which is an example of the formation of a new substance?

c) ice changing into liquid water
d) ice changing into water vapor

A 50-gram ice cube changes to liquid water and then to water vapor. What happens during this process?
a) The mass of the ice becomes greater than the total mass of the liquid water and the water vapor.
b) The mass of the liquid water becomes greater than the total mass of the ice and the water vapor.
c) The total mass of the ice, liquid water, and the water vapor stays the same.
d) The total mass of the ice, liquid water, and the water vapor decreases.

Outer space can be extremely cold. How does a space suit allow a human to survive the cold of space?
a) A space suit is made of insulating materials that slow the movement of heat.
b) A space suit is made of good conductors that move heat easily.
c) A space suit is made to absorb all surrounding heat.
d) A space suit is made to reflect all light.

How does a warm can of soda become cold when it is placed in a container of ice?
