• increase motion

• decrease volume

• increase pressure

What is happening when a solid is becoming a liquid?

• The particles decrease in motion, collapsing the organized structure.

• The increased movement of particles pushes them completely out of position, collapsing the organized structure.

• The particles increase in motion, causing the organized structure to flatten into a smaller shape.

• A particle party!

How doe the particles in a gas behave?

• Neatly organized without any movement.

• Move around trapped in a small volume and with the same surrounding particles.

• Move fast enough to break attractions and pushing other particles out of the way.

• Move freely in a straight line until they collide with another particle.

In which state of matter are the particles the farthest apart?

• gas

• liquid

• solid

Gas molecules can easily be compressed  because ___________. 

• gas molecules are soft
• gas molecules are far apart
• gas molecules follow the shape of the container

which of the following is true

• Gases do not move in straight line
• Most of the volume of gas is empty space
• Gas particles are not in constant random motion
• Gas particles attract each other
