Matter and Energy (TEKS 5.6) Review

Elliot investigated physical properties of six different materials. He made this chart to organize his data. Which categories describe the physical properties of each material? Each answer may be used more than once.

• Good insulator of thermal energy = B, E

  Is attracted by magnets = A, C, D

  Good conductor of electrical energy = A, C, D

• Good insulator of thermal energy = B, A

  Is attracted by magnets = A, C

  Good conductor of electrical energy = A, D

• Good insulator of thermal energy = C

  Is attracted by magnets = D, E

  Good conductor of electrical energy = A, B

Selah mixes some vinegar with water in a beaker. Which statement describes a change that occurs once mixed?

• The water becomes a solid when vinegar is added.

• The mass of the vinegar decreases in the water.

• The vinegar dissolves and spreads out evenly in the water.

• The volume of the water decreases when vinegar is added.

Jayla made a mixture with some iron filings and sand. She stirred 25 grams of gray iron filings into a container filled with 75 grams of white sand. Jayla observed that the mixture was white with flecks of gray. Which statement BEST explains her observation?

• Some mixtures maintain physical properties of their substances after combined.

• A mixture only has the physical properties of the substance with the greatest quantity.

• The physical properties of each substance always change when they are mixed.

• All mixtures have different physical properties than the properties of their separate substances.

Will compares the physical properties of four objects as shown (paper airplane, rubber ball, wood peg, rock). What physical properties do all of these objects have in common?

• They can all conduct electricity.

• They can all attract metal objects.

• They all have the same physical state.

• They all have the ability to dissolve in water.

George’s teacher blows up a stretchy red balloon and hands it to him to observe. Then George completes a concept map to organize his observations. Which words BEST complete the concept map to describe the physical properties of the blown-up balloon?

• A = outer part of balloon B = inner part of balloon C = physical state of matter D = air particles too small to be seen E = rubber looks red and stretchy

• A = color of balloon B = size of balloon C = weight of balloon D = air is visible E = rubber is hard and blue

• A = handle of balloon B = string of balloon C = chemical state of matter D = air particles are large E = rubber is rough and green

• A = top of balloon B = bottom of balloon C = physical state of water D = air particles are visible E = rubber is smooth and yellow

A spoonful of salt is dissolved in a glass of water. How will the mass of the saltwater solution compare to the mass of the water before the salt was added to it?

• The salt water will have less mass than the water.

• The salt water will have more mass than the water.

• The salt water will have the same mass as the water.

• The mass of the water and salt water must be measured in order to know.

Which statements describe the properties of the substances after being combined into solutions? Choose the TWO correct answers.

• A. A solution of lemon juice and sugar has gas and liquid states of matter.

• B. Lemon juice and salt have the same mass before and after combining in a solution.

• C. Mass is not conserved when solutions are made with lemon juice.

• D. Matter is conserved in a solution of sugar and lemon juice that has the mass of both samples combined.

• E. The mass of the two solutions is identical since they both have the same amount of matter.
