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?
because the heat of the sun caused the plastic to expand
The temperature decreased, causing the beam to contract.
by conduction
water vapor changing into liquid water
A gas forms after the liquids are mixed.
wood burning
Heat transferred through the ice cube into the pavement by conduction.
The water absorbed heat energy and evaporated.
Anya placed an ice cube on the sidewalk on a warm day. The ice cube soon melted to form a puddle. What process caused the ice cube to melt?
because the heat of the sun caused the plastic to expand
The temperature decreased, causing the beam to contract.

Tonya observes a mixture of two clear liquids in a container to see if a chemical change occurs. Which observation demonstrates the mixture is undergoing a chemical change?
because the heat of the sun caused the plastic to expand
The temperature decreased, causing the beam to contract.

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?
because the heat of the sun caused the plastic to expand
The temperature decreased, causing the beam to contract.
