Which of the following is a correct statement about the investigations?
All of the situations are examples of physical changes because all of the investigations exhibit changes to the physical properties.
None of the situations are examples of physical changes because they all involve a color change.
Situation 2 is a physical change because rust forming is a natural process.
Situations 1 and 3 are physical changes because no new substances are formed.
What type of change can be easily reversed?
chemical change
physical change
both chemical and physical changes
neither physical or chemical changes
Which of the following examples is a physical change but NOT a change of state of matter?
logs burning
water freezing into ice cubes
candle wax melting
paper being cut
A student is investigating changes with common classroom materials. Which of the following BEST describes the conclusion the student can make about the investigations?
The paperclip shows evidence of a physical change by changing the shape of the object, whereas the pencil eraser and hole puncher show evidence of a physical change by changing the size of the object.
All three investigations show evidence of a physical change due to a change in the color of the original substance.
The paperclip and hole puncher shows evidence of a physical change by changing the chemical properties of the original object, whereas the pencil eraser shows evidence of a physical change by changing the size of the object.
All three investigations show evidence of a physical change due to a change in state of matter.
A teacher takes a tray of ice cubes out of the freezer. Each student takes an ice cube and holds it in their hands. They make the observations listed in the chart. The student claims that changing the temperature of the water causes a physical change that turns water into ice.
Which argument BEST supports the student’s claim?
The ice cube is melting in the student’s hand since the hands are much warmer than the ice. Heat is being added to the ice, which causes the particles to move faster.
The ice cube is freezing in the student’s hand since the hands are much warmer than the ice. Heat is being removed from the ice, which causes the particles to move slower.
The ice cube is melting in the student’s hand since state is changing from a solid to a liquid. Heat is being removed from the ice, which causes the particles to move faster.
The ice cube is melting in the student’s hand since state is changing from a liquid to a solid. Heat is being added to the ice, which causes the particles to move slower.
Which of the following is a physical change?
Iron is oxidized to iron oxide
Aluminum metal is pounded into thin sheets
Copper reacts with a strong acid
Sodium metal explodes on contact with water
Jolene wants to experiment with sugar cubes. Which of the following causes a sugar cube to only change physically, not chemically?
burning the sugar cube with a match
crushing the sugar cube and dissolving it in water
dehydrating the sugar cube with sulfuric acid
chewing the sugar cube and digesting it
A physical change occurs when…
both the appearance of a substance and its phase change.
the appearance of a substance changes but its phase does not.
the phase of a substance changes but its appearance does not.
neither the appearance of a substance nor its phase changes.
Diane draws a picture on a piece of paper and then folds it into a paper airplane. She throws it at her little brother, and it hits him in the head. He responds by ripping up the paper. Which of the following is an example of a physical change?
ripping up the paper
folding the paper into an airplane
drawing on the paper
all of these
