6th grade Matter

Jason is comparing substances by investigating a ceramic cup with hot water inside and water vapor above the cup. What can he say about the motion of the particles in ALL of the substances? SC.8.P.8.1

• They do not move.

• They are always moving.

• The move past each other slowly.

• They move very fast in all directions.

In which state of matter are the particles able to move around one another? SC.8.P.8.1

• Gases only

• Liquids only

• Gases and liquids only

• Gases, liquids, and solids

What term describes the state of matter in which the attractive forces between particles are the greatest? SC.8.P.8.1

• gas

• solid

• metal

• liquid

At room temperature, nitrogen is a gas and mercury is a liquid. Which claim describes how the particles of nitrogen gas compare to the particles of liquid mercury? SC.8.P.8.1

• The particles that make up nitrogen gas are expanding.

• The particles that make up nitrogen gas are closer together.

• The particles that make up nitrogen gas are moving more rapidly.

• The particles that make up nitrogen gas have greater attractive forces between them.

What happens to the particles of a liquid when energy is removed from them? SC.7.P.11.1

• The motion of the particles increases

• The motion of the particles stays the same.

• The distance between the particles increases.

• The distance between the particles decreases.

What will be the effect on a cube of ice in a closed container left on a counter at room temperature for 30 minutes? SC.7.P.11.1

• The cube will continue to have the same shape and volume.

• The cube will melt and take on the shape and volume of the container.

• The cube will melt and take on the volume of the container, but not the shape.

• The cube will melt and take on the shape of the container, but not the volume.

What happens when you add energy to a liquid? (SC.8.P.11.1)

• Melting and it will turn into a solid.

• Freezing and it will turn into a solid.

• Evaporation and it will turn into a gas.

• Condensation and it will turn into a gas.

After a piece of paper is burned, the ashes weigh less than the original paper. Which statement BEST explains this difference in mass? SC.8.P.9.1

• Some of the particles of the paper have been transformed into heat.

• Some of the particles of paper have been destroyed, so it weighs less.

• The particles of the paper were chemically changed resulting in new substances that include gases.

• The particles of the paper change state from solid to gas, so the ashes weigh less than the original paper.

Marco accidentally broke a crayon while coloring. Which of the following best compares the broken crayon to the original crayon? (SC.8.P.9.1)

• The density of the crayon has decreased since the crayon is smaller.

• The crayon went through a chemical reaction since there are more pieces of the crayon.

• The crayon went through a chemical change because the shape of the crayon changed.

• The total mass of the broken crayon pieces are the same as the original crayon since matter was not lost.

What happens to the mass of a whole piece of paper when cut into pieces and placed in a pile? (SC.8.P.9.1)

• The mass of the whole piece of paper and pile of paper will be the same.

• The whole piece of paper doesn’t have a mass because it is too light.

• The mass of the whole piece of paper will be less than the mass of the pile of paper.

• The mass of the whole piece of paper will be more than the mass of the pile of paper.
