........... take the shape of the container and has a fixed volume.

• A solid

• A liquid

• A gas

• Plasma

A gas has .............. (it takes the shape of the container) and ............... volume.

• fixed - fixed

• fixed - no fixed

• no fixed - no fixed

• no fixed - fixed

In a solid, particles ...............

• are far away from each other and can move around freely.

• are close together, cannot move, and just vibrate about a fixed point.

• are further apart and can slide past each other.

• are further apart and can move freely.

In a liquid, particles ...............

• are far away from each other and can move around freely.

• are close together, cannot move, and just vibrate about a fixed point.

• are further apart compared to solid and can slide past each other.

• are further apart and can move freely.

In a gas, particles ...............

• are far away from each other and can move around freely.

• are close together, cannot move, and just vibrate about a fixed point.

• are further apart compared to solid and can slide past each other.

• are much further apart and can move freely (or randomly).

A solid has a fixed shape and fixed volume because ...............

• There is no intermolecular force to hold particles together

• Week intermolecular force holds particles together

• Strong intermolecular force holds particles together

A gas has no fixed shape and no fixed volume because ...............

• There is a very weak intermolecular force to hold particles together

• Week intermolecular force holds particles together

• Strong intermolecular force holds particles together
