Matter is made of particles

What are the three states of matter?

• Solid, Liquid, Gas

• Solid, Liquid, Plasma

• Liquid, Gas, Plasma

• Solid, Gas, Plasma

Answer explanation

The three primary states of matter are Solid, Liquid, and Gas. Solids have a definite shape, liquids take the shape of their container, and gases fill the available space. Plasma is a fourth state but not one of the three basic states.

Why can't we see the particles that make up matter?

• They are energy.

• They are always moving.

• They are too small to see.

• They are without any mass.

Answer explanation

The correct answer is 'They are too small to see.' Matter is made up of particles like atoms and molecules, which are at a scale far smaller than what the human eye can detect.

What is the simplest form of all matter?

• Atoms

• Cells

• Elements

• Molecules

Answer explanation

Atoms are the simplest form of matter, as they are the basic building blocks of all substances. Elements consist of one type of atom, while molecules are made up of two or more atoms bonded together.

What are the building blocks of all matter?

• Water

• Oxygen

• Atoms

• An element

Answer explanation

Atoms are the fundamental building blocks of all matter, as they combine to form molecules and elements. Water and oxygen are made of atoms, but they are not the basic units of matter themselves.

Matter is made of particles that are too small to see, but can be detected in a variety of ways. When sugar dissolves in a glass of water, it can no longer be seen. Cite evidence that shows the sugar still exists in the glass of water even after it cannot be seen.

• If the glass is left out overnight and untouched, the sugar will crystallize and sink down to the bottom of the glass.

• The amount of space the glass takes up before the sugar is added is the same amount of space taken up after it dissolves.

• If the glass is put in the freezer overnight, the sugar will float to the top of the glass and the water will freeze under it.

• The weight of the glass of water plus the added sugar will equal the weight of the glass of water after sugar has dissolved.

Answer explanation

The weight of the glass of water plus the added sugar remains the same after the sugar dissolves, indicating that the sugar still exists in the solution, even if it is not visible.

Matter is made of particles that are too small to see, but can be detected in a variety of ways. Air pumps are used to fill things like bicycle tires and footballs.

If you were to place your finger over the opening of the air tube, you would be unable to push the pump down. Which best explains why this would occur?

• 
  The pump only pushes down when the tube is attached to a football or bicycle tire.

• The pump would be unable to move past the blocked air in the tube, which takes up space.

• Placing a finger over the opening forces more air into the tube and pushes the pump upward.

• Covering the opening prevents air from coming into the pump, so the pump is unable to work.

Answer explanation

The correct choice explains that when you cover the opening, the air in the tube is blocked, preventing the pump from moving down. This blockage occurs because air occupies space, making it impossible for the pump to function properly.

"Did you know that the air is made up of mostly particles of nitrogen and oxygen?" Sam asked his lab partner, Jose.

Jose responded, "How can you tell anything is there? We can't see the air."

Sam said, "I know, let's do some experiments!"

Sam and Jose took a paper towel and wadded it. They stuffed the wadded up paper towel into a plastic cup. When they held the cup upside down the paper towel stayed inside the cup and did not fall out.

They filled a bowl with water and slowly lowered the cup into the water. Once the cup was completely underwater, they slowly raised the cup out of the water. They pulled the wad of paper out and it towel was dry!

With this experiment, Sam and Jose demonstrated that air, even though it is invisible, is all around us and

Responses

• Air has weight.

• Air moves around.

• Air takes up space.

• Air is made up of several gases.

Answer explanation

Sam and Jose's experiment showed that the air inside the cup prevented the paper towel from getting wet, demonstrating that air occupies space. This supports the idea that air takes up space, even though it is invisible.

Did you know that the air is made up of particles?" Sam asked his lab partner, Jose.

Jose responded, "How can you tell anything is there? We can't see the air."

Sam said, "Take a look at this bubble wrap."

Jose answered, "Yes! I can see right through it. See, there is nothing there!"

The bubbles are filled with air. Those bubbles Sam popped demonstrate that air, even though it is invisible, is made up of particles that

• Air has mass.

• Air has weight.

• Air takes up space.

• Air is made up of several gases.

Answer explanation

The bubble wrap demonstrates that air occupies space, as the bubbles are filled with air. When Sam pops them, it shows that even though air is invisible, it still takes up space.

Choose THREE examples that show matter is made of particles that take up space, even though they are too small to be seen.

• A basketball player becomes tired by the end of his game.

• A plastic tube is easier to bend than metal.

• When pumping up a basketball, the ball expands as air is added.

• As a balloon is blown up with air, it stretches and gets larger.

• When boiling salt water, the water evaporates and salt is left behind.

Answer explanation

The correct choices demonstrate that matter consists of particles. Pumping air into a basketball and a balloon shows how particles occupy space, while boiling salt water illustrates that water particles evaporate, leaving salt behind.

Look at the image of a basketball being over-inflated to the point of exploding. Drag and drop the conclusion that this experiment likely provides evidence for.

• As air is removed from the basketball, it loses mass and deflates.

• As more particles are pumped into the basketball, the more matter is taking up space until there is too much matter, and the ball explodes.

• As explosives are pumped into the basketball, it causes the basketball to explode.

• As oxygen and nitrogen are combined into a basketball, they create an explosive compound, nitrous oxide, that makes the ball explode.

Answer explanation

The correct choice explains that as more air particles are added to the basketball, the volume increases until it exceeds the material's capacity, leading to an explosion. This aligns with the observed outcome in the image.
