art B. hat you have to do: 1. Fill your mouth with air. Press your cheeks with your fingers. Answer the following questions: 2. a. Did air occupy space in your mouth? b. Were you able to press your cheeks with your fingers? Why? A JST c. When you pressed one of your cheeks, did you feel the air moving to the other side of your cheek? Explain what happened.
Answer:
A. Yes, the air would occupy space in your mouth when you fill it with air. Air is a gas and like all gases, it has volume and occupies space.
B. No, you wouldn’t be able to press your cheeks with your fingers once you fill your mouth with air. The air in your mouth creates pressure that prevents your fingers from compressing your cheeks.
C. No, you wouldn’t feel the air moving to the other side of your cheek when you press one cheek. This is because the air in your mouth is contained by your lips, teeth, and the roof of your mouth. Pressing one cheek does not create a pathway for the air to move to the other side.
