While Karen was cooking dinner, she noticed that several ingredients went through chemical and physical changes. Which cooking process is an example of a physical change?
boiling soup
frying eggs
baking cookies
toasting bread
Amir is helping his uncle in his restaurant, where he notices many examples of physical and chemical changes. Which one of the following describes both a physical and chemical change?
Frozen lemonade melts and is blended with raspberries. Then, it is frozen again.
Sugar cubes are crushed, then put into a pan to cook. The sugar begins to melt and then burns.
Raisins, almonds, and pumpkin seeds are mixed together. The mixture is then distributed among five containers.
Butter is softened and mixed into a cookie recipe. Then, it is placed in the refrigerator to cool.
When a substance has large or strongly attracted particles, they do not flow freely. For example, water flows very quickly compared to honey. Which property of liquids does this example illustrate?
viscosity
crystallinity
amorphousness
surface tension
On a hot summer day, Tameka spilled water on the sidewalk, but a few hours later there was no evidence of the water. What most likely happened to the water?
boiling and sublimation
sublimation and vaporization
vaporization and evaporation
boiling and evaporation
Salia is creating a diagram to show how rocks go through the steps of the rock cycle. Her diagram shows the processes that occur to change rocks from one type into another type.

Which of the following can occur right after a rock is weathered?
It gets compacted and forms sedimentary rock.
It melts and forms igneous rock.
It forms metamorphic rock.
The sediment can form magma.
Jonah and Rachel volunteer at the recycling center sorting and organizing recyclable objects. Jonah is sorting aluminum cans and crushing the cans to fit more in the bag. Rachel is sorting metal and steel objects into appropriate bins. Rachel notices that many objects have rusted. Rusting is a chemical change that some metal and steel objects undergo when they are exposed to oxygen. Which option best describes a chemical change?
a change in matter that produces one or more new substances
a change from solar energy to chemical energy
a change from a liquid state to a gas state
a change in form or appearance of matter
Jonah and Rachel volunteer at the recycling center sorting and organizing recyclable objects. Jonah is sorting aluminum cans and crushing the cans to fit more in the bag. Rachel is sorting metal and steel objects into appropriate bins. Jonah realizes that even though he is crushing the cans, the amount of material in each can is unchanged. Which of the following describes the process that is taking place?
a change in mass of an object
a change in chemical bonds within the object
a change in matter that produces one or more new substances
a change in form or appearance of matter
Walt is taking an overnight backpacking trip on the Appalachian Trail in Georgia. He picks up his backpack from the ground, puts it on his back, and walks five miles before he stops and puts the pack down near a stream. He stands near the stream and fishes for dinner, but doesn't catch anything. “I guess I’ll have soup for dinner!” he thinks, and lights a fire to heat up his soup. At what point in the day did Walt do the most work, according to the scientific definition of the word?
when Walt was thinking about what to have for dinner
when the soup was cooking on the fire
when Walt was carrying the pack five miles
when Walt was picking up and putting down the pack
Beth is taking a trip on an airplane. Which statement explains what happens to the gravitational potential energy of the plane as it takes off and soars higher?
It becomes greater as the plane rises higher.
It is all used up as the plane rises higher.
It decreases as the plane rises higher.
It is changed into kinetic energy as the plane rises higher.
There is a popular saying that “an apple a day keeps the doctor away.” Believing the advice, Samar picks an apple off a tree in the backyard and takes a bite. What happens to the energy stored in the apple when it is eaten?
The stored energy is released and converted.
All the energy is destroyed by stomach acid.
The body absorbs the released energy.
All the energy is returned to the environment.

lighter
thicker
dense
underwater
Continental Crust
Oceanic Crust
A glass of ice water sat out in the sun, and the ice absorbed heat and eventually became liquid water. What did the states of the ice and the liquid water have in common?
Neither had definite shape or volume.
Both had definite shape.
Both had definite shape and definite volume.
Both had definite volume.
The diagrams show the arrangement of the particles in a sample of a material. The particles in the left diagram undergo a change in state, resulting in the arrangement in the diagram on the right. What change of state most likely took place?

melting
freezing
boiling
condensation
When circumstances are right, most materials undergo a process called thermal expansion. Which statement best describes the cause and effect of thermal expansion?
Matter is cooled, and its particles move closer together.
Matter is cooled, and its particles spread out more.
Matter is heated, and its particles spread out more.
Matter is heated, and its particles move closer together.
How is the thermal expansion of a metal door related to kinetic energy?
The door expands when it moves on its hinges and is no longer held in place by the door frame.
As energy is transferred to the door, the particles in the door increase in kinetic energy and move farther away from each other.
As energy is transferred from the door, the particles in the door decrease in kinetic energy and move closer together.
The faster the door moves back and forth, the more thermal expansion it experiences.
A rock cycle diagram is shown below. What happens to rocks at location 3 in the diagram?

Compacting and cementing
