• black pavement because it reflects heat

• white pavement because it reflects heat

• white pavement because it absorbs heat

Alex and Jade are conducting an experiment to measure how the sun

affects the evaporation of water. Alex places 50mL of water in the shade.

Jade places 50mL of water in direct sunlight. What will the students

most likely observe?

• The water in the sun will be warmer, causing the water to evaporate

  more quickly.

• The water in the shade will be cooler, causing the water to evaporate

  more quickly.

• The water in the shade will be warmer, causing the water to

  evaporate more slowly.

• The water in the sun will be cooler, causing the water to evaporate

  more slowly.

Which best explains why there are gaps between the concrete

sidewalks?

• When temperatures get cold, the gaps allow the concrete to expand

  without cracking.

• When temperatures get hot, the gaps allow the concrete to expand

  without cracking.

• When temperatures get cold, the gaps allow the concrete to contract

  without cracking.

• When temperatures get hot, the gaps allow the concrete to contract

  without cracking.

During winter months, people worry about the water pipes in their house

breaking. Which best explains why?

• Water in pipes can freeze, expand, and the added pressure can break

  water pipes.

• Water in pipes can melt, expand, and the added pressure can break

  water pipes.

• Water in pipes can freeze, contract, and the added pressure can

  break water pipes.

• Water in pipes can melt, contract, and the added pressure can break

  water pipes.

Why would someone living in a cool climate paint the bottom of their

pool a dark color?

• The dark color will reflect energy from the sun into the water to cool

  it.

• The dark color will reflect energy from the sun into the water and

  warm it.

• The dark color will absorb energy from the sun and transfer heat to

  the water.

• The dark color will absorb energy from the sun and transfer coolness

  to the water.

Which best explains why a sealed glass bottle, that is full of water,

would most likely burst or crack if it is left in a freezer?

• Glass freezes at a lower temperature than water.

• Water expands when it freezes.

• Glass expands when it freezes.

• Water contracts when it freezes.

Why will it not be a good idea to carry extremely hot liquids in a thin

metal container?

• Heat travels through metal easily.

• The metal container will remain cool.

• Cold air travels through the metal too easily.

Allen hurt his hand at work. The doctor said that he needed to wear a

special device on his hand to help it heal. The nurse put a sheet of

plastic into hot water. When she took the plastic out of the water she

molded it to his hand. The brace fit perfectly. What was most likely the

reason the nurse put the plastic in the hot water prior to molding to

Allen’s hand?

• so the plastic would be clean

• so the plastic would change colors

• so the plastic would not be too cold

• so the plastic could be molded easily
