Different types of solids behave differently due to their crystalline structure. Which statement best describes plastic?

Plastic is an amorphous solid because it can be gradually heated and cooled to take on a specific shape.

Plastic is a crystalline solid because it melts at a distinct temperature.

Plastic is an amorphous liquid because it does not melt at a specific temperature.

Plastic is a crystalline liquid because it does not melt at a distinct temperature.

Matter can be described and classified by its observable properties. One property of solids, liquids, and gases is they all have volume. Which statement best defines the volume of an object?

the amount of matter in an object

the amount of space that matter occupies

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?

Sugar cubes are crushed, then put into a pan to cook. The sugar begins to melt and then burns.

Frozen lemonade melts and is blended with raspberries. Then, it is frozen again.

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?

amorphousness

surface tension

crystallinity

viscosity

Maria buys an air purifier to separate a mixture of dust and allergens from the air. Which type of separation method does an air purifier use?

magnetic attraction

evaporation

distillation

filtration

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

boiling and evaporation

sublimation and vaporization

vaporization and evaporation

In the 1600s, Robert Boyle conducted experiments for situations in which the volume of a gas is changed. Which of the following describes Boyle’s Law?

When the pressure increases, the volume decreases.

When the temperature decreases, the volume increases.

When the temperature decreases, the volume decreases.

When the pressure increases, the volume increases.

After using an air mattress, Lucy opens the valve to deflate it and air begins rushing out of the mattress. When will the air most likely stop rushing out of the mattress?

when all of the air is out of the mattress

when the air pressure in the mattress is equal to atmospheric pressure

when the air pressure in the mattress is greater than atmospheric pressure

when the air pressure in the mattress is less than atmospheric pressure

Lisa conducts an experiment of gas trapped in a container. She keeps the volume of the gas constant but increases the temperature. Which statement correctly explains what will happen to the pressure?

The pressure decreases because the gas particles are trapped in the container.

The pressure increases because the temperature increases and more gas particles are formed.

The pressure increases because the gas particles begin to move quickly and exert more force on the container.

The pressure stays the same because the volume of the gas does not change.

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 carrying the pack five miles

when the soup was cooking on the fire

when Walt was thinking about what to have for dinner

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 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.

It becomes greater as the plane rises higher.

Scientists use measurements of air temperature to predict how air masses will behave. On a warm day, if a very cold air mass suddenly rushed in, what could scientists predict about what would happen to the air mass and the resulting change in energy?

The cold air would not cause the density of the warm air to change. The thermal energy would increase as the temperature decreased.

The cold air would cause the warm air to sink as density increases. Thermal energy would be released by the warm air and temperatures would decrease.

The cold air would cause the warm air to sink as density decreases. Thermal energy would remain the same.

The cold air would cause the warm air to rise as density decreases. Thermal energy would remain the same.

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?

All the energy is returned to the environment.

All the energy is destroyed by stomach acid.

The stored energy is released and converted.

The body absorbs the released energy.

A chemist is comparing the melting temperature of different lead alloys. The chemist is interested in amounts between 40% and 60% of the second metal. Which alloy contains particles with the greatest change of kinetic energy in this span?

Pb Te

Pb Cu

Pb Sn

Pb Bi

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?

Both had definite shape.

Both had definite volume.

Both had definite shape and definite volume.

Neither had definite shape or 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?

freezing

boiling

condensation

melting

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 spread out more.

Matter is heated, and its particles move closer together.

Matter is heated, and its particles spread out more.

Matter is cooled, 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.

The faster the door moves back and forth, the more thermal expansion it experiences.

As energy is transferred from the door, the particles in the door decrease in kinetic energy and move closer together.
