Question 1

A student places a sealed air-filled balloon into a freezer. After two hours, the balloon has shriveled and reduced in size. Which statement best explains this phenomenon using the particle model of matter?

Gas particles escaped through microscopic holes in the balloon rubber. Gas particles slowed down, moved closer together, and exerted less pressure on the balloon walls. Gas particles destroyed themselves due to the cold temperature inside the freezer. Gas particles condensed into liquid water that filled the bottom of the balloon.

Correct Answer:

Gas particles slowed down, moved closer together, and exerted less pressure on the balloon walls.

Question 2

A metal sphere just barely fits through a metal ring at room temperature. After heating the metal sphere over a flame for two minutes, it no longer fits through the ring. What happened to the particles inside the metal sphere?

Heating added new metal particles, increasing the total weight of the sphere. Heating caused the metal particles to absorb energy, vibrate faster, and spread further apart. Heating melted the outer layer of the sphere into a thicker gas layer. Heating transformed the metal particles into larger non-metal atoms.

Correct Answer:

Heating caused the metal particles to absorb energy, vibrate faster, and spread further apart.

Question 3

A glass of iced water sits on a kitchen table on a humid summer afternoon. After 15 minutes, liquid water droplets form on the outside surface of the glass. Where did this water come from?

Cold water seeped through microscopic pores in the glass walls. Ice cubes inside the glass melted and overflowed down the outer wall. Water vapor particles in the warm air collided with the cold glass, lost energy, and condensed into liquid. Hydrogen and oxygen gases chemically reacted on the glass surface to produce new water molecules.

Correct Answer:

Water vapor particles in the warm air collided with the cold glass, lost energy, and condensed into liquid.

Question 4

A student measures 100 grams of liquid water and 15 grams of table salt. She stirs the salt into the water until it completely dissolves and disappears from view. What will be the final mass of the saltwater solution?

100 grams, because the salt dissolved and lost all its mass. 115 grams, because total mass is conserved during physical dissolving. 85 grams, because dissolving causes some water to evaporate instantly. 130 grams, because salt particles react with water to gain mass.

Correct Answer:

115 grams, because total mass is conserved during physical dissolving.

Question 5

Three identical containers hold water in solid (ice), liquid, and gas (steam) phases. How do the motion and arrangement of water molecules compare across these three states?

Gas particles are fixed in rigid rows; liquid particles float freely; solid particles move fastest. Solid particles vibrate in fixed positions; liquid particles slide past one another; gas particles move rapidly and independently. Solid particles move fastest; gas particles are held tightly by strong bonds; liquid particles do not move. All three states have identical particle speeds, but gas particles are smaller than solid particles.

Correct Answer:

Solid particles vibrate in fixed positions; liquid particles slide past one another; gas particles move rapidly and independently.
