Final Review - Unit 2

Coach Masaryk decided to learn how to ski. As they move up the mountain they have to work harder to breathe. What happened to the atmospheric pressure as they hiked up the hill?

• Increased

• Decreased

• Stayed the same

• Disappeared

What happens to the pressure of a gaseous system as temperature increases?

What happens to the pressure in a gaseous system as volume decreases?

What happens to the pressure of a gaseous system if the number of particles decrease?

The gas in the box on the right has a lower pressure than the gas in the box on the left.  Using a separate sheet of paper, craw “whooshies” on the particles in each box to represent their relative motion.  Explain. Show your diagram to Coach Masaryk to check comprehension.
