Particles

You trap particles inside a syringe then push the plunger down.

• There are the same amount of air particles in each syringe.
• There are more particles in the compressed syringe. 
• There are fewer particles in the compressed syringe.
• The particles in the compressed syringe get smaller.

You trap particles inside a syringe then pull the plunger up.

• There are an equal number of particles in each syringe.
• There are more particles in the second syringe.
• There are fewer particles in the second syringe.
• The particles in the second syringe are expanded.

What is between air particles?

• Particles of oxygen
• Particles of nitrogen
• Nothing
• Other elements

The smallest piece of anything that still has the properties of that thing is called

• an element.
• a particle.
• a substance.
• a gas.

Air particles inside a closed object are

• compressed so that the particles bond to each other.
• vibrating rapidly until they break the bonds holding them to other particles.
• constantly moving and bumping into other particles and the object.
• perfectly still because they have enough room.

What happened to the air particles outside the blue cube when the syringe was compressed?

• The air particles became closer together.
• The air particles became farther apart.
• The air particles stayed the same distance apart.
• The air particles were forced inside the blue cube.

What happened to the blue cube when the syringe was compressed?

• The cube became larger.
• The cube became smaller.
• The size of the cube did not change.

You compress a closed syringe system and then let it go. Why does the plunger return to its original position?

• More air particles rush into the syringe and push the plunger up.
• The air particles outside the syringe pull the plunger up.
• The air particles inside the syringe push the plunger up.
• The air inside tried to get out.

After compressing the syringe, and releasing the plunger, why does the plunger stop moving at its original position.

• The particles inside and outside the plunger are hitting with equal force.
• The air particles are finally all able to escape the inside of the syringe.
• The air particles have as much room as they need.
• The air particles bond to each other.
