Which statement BEST describes what happens as water changes from one state to another? 

• As water is cooled, it freezes and changes from a solid to a liquid. 

• As water is cooled, it condenses and changes from a gas to a liquid.

• As water is heated, it evaporates and changes from a liquid to a solid. 

• As water is heated, it melts and changes from a gas to a solid.

Students observe a glass of ice and water. The ice starts as cubes. After 10 minutes, the cubes have decreased in volume, and they appear more rounded.

 

Which statement best explains the students' observations?

• The ice is a solid with no definite shape. As the ice cools, it begins to change into a gas whose shape and volume change.

• The ice is a solid with a fixed shape. As the ice warms, it begins to change into a liquid whose shape changes.

• The ice is a liquid with no definite shape. As the ice cools, it begins to change into a solid whose shape remains the same.

• The ice is a solid with a fixed shape. As the ice cools, it begins to change into a liquid whose shape changes.

During a science lesson, a teacher placed a beaker with 50 mL of water near a sunny window. He placed another beaker with 50 mL of water in the closet. 

Two days later, the beaker near the window was empty while water remained in the beaker that was placed in the closet. 

What most likely happened to the water in the beaker near the window? 

• The Sun changed the water from a liquid to a solid. 

• The Sun’s light caused the water to condense.

• The water changed from a gas to a liquid.

• Heat from the Sun caused the water to evaporate.

The two pictures show part of an investigation. A magnet, a book, and a paper clip are on a sheet of lined paper. In Picture 1 a student slides a magnet closer to the book. The student holds the book still in both pictures.

Which two statements about this investigation can be supported by the result shown? Select TWO correct answers.

• The force of gravity acted on the magnet, the book, and the paper clip.

• The magnet applied a force to the right which acted only on the paperclip.

• The magnet applied a force to the left which acted only on the paperclip.

• A magnetic force acted on the magnet, the book, and the paper clip.

• The student's hand applied a force to the left which acted on the magnet.
