Unit 2 Chemistry: Day 2 - States of Matter

Chemistry Day 2: States of Matter Classwork

Matter is anything that has mass and takes up space (volume).

All matter is made up of atoms. As you know, they are WAY too small to be seen with our eyes. 

When some atoms are bonded (or attached) to each other, they make up bigger particles called molecules.These particles are still too small to be seen with our eyes.

Atom:                                                                         Molecule:

The way molecules move and are attracted to each other causes matter to be in a certain STATE.

Reviewing Solids, Liquids, and Gases

1. Watch the Brainpop Video: States of Matter and complete the chart on your paper.

State of Matter	Shape	Volume	Speed of Particles	Drawing that Represents the Molecules	Drawing of an Example
Solid	fixed shape	fixed volume	SLOW: Particles vibrate in place)
Liquid	not fixed	fixed volume	MEDIUM:  particles move fast enough to overcome some of the attraction between them
Gas	not fixed	not fixed	FAST:  move fast enough to overcome nearly all of the attraction between them

 Chemistry Day 2 Lifework: States of Matter

   1.)   Draw water in the three different states of matter, and fill in the blanks.

 

Solid: __________                                    Liquid: water                                     Gas: _____________


2)   True or False:

a)    All matter is made out of atoms. _____________

b)   Atoms that are bonded to each other are called molecules. ___________

c)    In a solid, the molecules stand completely still. ____________

d)   A liquid will increase in volume if placed in a larger container. _____________

e)    A gas has no definite shape or volume. _______________

   3)   Plasmas can be found in _________________

a)    Ocean water

b)   Gold

c)    Lightning

d)   Helium

4)   The state of matter where the molecules have the strongest attraction to each other is:

a)    Solid

b)   Liquid

c)    Gas

d)   Plasma

5)   A gas can change shape and volume because:

a)    The molecules are strongly attracted to each other

b)   There is empty space between molecules that changes

c)    The molecules keep bumping and sliding against each other

d)   A gas cannot change shape or volume.

66)   Use your notes to draw how the molecules in a liquid may look:
