Gas and Atoms

1. List three more everyday examples of phase change.
-snow melting and freezing into ice
-fuel being changed into gas for cars
-ponds freezing over to have a layer of ice

1. Describe the motion of atoms and molecules in a gas.
the atoms and molecules bounce off one another each time they come in contact with eachother. they never bond, but reflect off of eachother and spread around.
2. How are the behavior and arrangements of gas molecules similar to and different from soccer players running in the field?
the molecules are similar to soccer players running on a field when they continually move and dont stop. players in soccer never stop moving during the game, and the gas molecules dont stop moving and keep bouncing off one another.

1. Record the average number of dashed lines there are per atom of each liquid.
the average number of dashed lines are 3-4 per atom
2. Describe the motion of atoms and molecules in a liquid.
the atoms are tight and compact, they bounce off of each other. they generally dont leave a certain section of the liquid, and stay in the same area.
3. How far do the atoms in a liquid appear to travel? Press the "Randomly pick an atom and show its trajectory" button, take a snapshot and place a snapshot image that you think best answers this question in the box below.
4. How does the motion of folks at a festival resemble a liquid?
all the folks move their arms and themselves in a very concentrated manner and stay generally in the same spot. they bounce up and down, just like how the aroms and molecules move up and down.

1. Stop the model and estimate how many dashed lines there are for atoms inside the
