Matter and Its Interactions Progress Monitoring

 Samuel does an experiment of a closed system by using a sugar-water mixture. He follows the steps and makes the observations shown in the table.

Which correctly predicts the weights of the cup throughout the experiment?

• The weight of the cup increases after steps 2, 4, and 6.

  
  

• The weight of the cup increases after steps 2 and 4 and remains the same through step 6.

  
  

• The weight of the cup increases after step 2 and remains the same afterwards.

  
  

• The weight of the cup remains the same throughout the experiment.

Leah weighs three ice cubes and finds that each ice cube weighs 15 grams. She places the cubes into a covered beaker that weighs 200 grams.  She leaves the covered beaker with the ice cubes inside on a table overnight.  Leah returns in the morning to find the covered beaker contains water.

What will be the total mass of the beaker and water?

• 245 g

• 230 g

• 200 g

• 215 g

Sammy pours different liquids into a beaker. He he wants to know that by combining the liquids, if a new substance forms inside the beaker.

How will he most likely know if a new substance occurred?

• The combined material is a liquid.

  
  

• The combined material has a density between that of either liquid.

  
  

• The combined material has the volume of both liquids combined.

  
  

• The combined material has an odor.

During a science experiment, Alex observes that a metal rod expands when heated.

What is the most likely reason for the expansion of the metal rod?

• The metal rod absorbs moisture from the air.

• The metal rod contracts due to heat.

• The metal rod expands due to increased kinetic energy of particles.

• The metal rod changes its chemical composition.

During a lab experiment, Chris observes that a balloon shrinks when placed in a freezer.

What is the most likely explanation for this observation?

• The air inside the balloon contracts due to lower temperatures.

• The balloon material becomes more elastic in the cold.

• The air inside the balloon expands due to lower temperatures.

• The balloon absorbs moisture from the freezer.
