Which of these is an example of a gas?

• ice cube

• water in a glass

• piece of wood

• steam from a kettle

Based on the image, which statement best describes the changes in physical state that occurred?

• The water in the tray started as a liquid, turned into a solid when frozen, and melted back into a liquid in the glass.

• The water in the tray started as a liquid, condensed into a gas, and then froze into a solid.

• The water in the tray started as a liquid, turned into a solid when melted, and turned back into a liquid when frozen in the glass.

A materials scientist is developing a new substance for use in extreme environments. They observe its behavior under three different conditions: Condition A: The substance flows but maintains a constant volume. Condition B: The substance expands to fill its container entirely. Condition C: The substance maintains a fixed shape and resists compression. Which condition represents the substance in a gaseous state?

• Condition A

• Condition B

• Condition C

• None of the above

What happens to a liquid when it is heated?

• It freezes.

• It turns into a gas.

• It stays the same.

• It turns into a solid.

Which of these represents the particles of a solid?

• They spread far apart and move fast.

• They are close together and vibrate in place.

• They are spread out and take the shape of their container.

• They are far apart and bounce off each other.

A student observes water in a sealed container as it's heated from -10°C to 110°C.

Compare the physical states of water at the following temperatures:

Which statement correctly compares these states?

• Sample A and Sample E have the most rigid particle arrangement, while sample C has the least.

• Sample B and Sample D show the most dramatic changes in particle movement.

• Sample C and Sample E take the shape of their container, while sample A does not.

• Sample A and Sample C have similar particle movement, while sample E has much more.
