If we bring cheesy pizza into the classroom and placed it at the door, is that the high or low concentration?
a. After about 10 minutes, would the molecules fill up the room?
b. If so, is that the molecules moving from high to low concentration or low to
high? Explain your choice

answer: c.

explanation:

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
