When heat energy is added to water in a pot on a stove, what changes occur to the water?

The diagram shows the particle vibration of an unknown substance in a container. Which substance can likely be represented by the motion of the particles in the diagram?

A student leaves a bowl of ice cream on a table, where it turns to liquid. The student places the liquid ice cream back into the freezer overnight. How do the motion of the particles in the ice cream change when it is placed in the freezer?

An ice cube is placed in a glass, where it slowly begins to melt. What is true about the motion of the particles in the ice cube as it changes states?

The image shows three particle arrangements for water. How can the phases be classified?

A student reads three statements from a science book.

The student uses the information to make a particle model representing the molecules of water in the

three states: ice, water, and water vapor. Which model is correct?

The particle diagram represents phase change of a substance. Between which two phases does the substance change?

The diagram should represent a substance undergoing a change. Which particle arrangement completes the diagram if the substance is melting?

How does the particle arrangement of water change when heated from 46 degrees Celsius to 102 degrees Celcius

What likely caused a change in state from sample A to samle B?

When water is changed from a liquid to a gas, what occurs?

Water puddles on a sidewalk evaporate when the Sun heats the water. Which of these best describeswhat is happening as the water evaporates?

Yuko designed an experiment to test the effect of heating and cooling on air. She blew up two balloons to similar sizes and measured their circumferences. She placed one balloon in a freezer for one hour

and left the second balloon on the table. After one hour she measured their circumferences again. She then left both balloons on the table for one more hour. The graph below shows the change in the sizes

of the balloons during the experiment.

Which statement best explains the differences seen between the two balloons during the experiment?

A student is examining three diagrams that show particle arrangements in a solid, liquid, and gas.

What types of particles have the least amount of kinetic energy?

Which statement about all living organisms is true?

Which system’s primary function is to provide shape and structure to the human body?

Which diagram correctly shows the levels of organization in a human?

The graph shows how the temperature of a substance changes over time when heat is applied. Which particle diagram best represetns the change in the substance from location 1 to location 2?
