Which container below has the lowest air pressure if the balloons are similar? Copyright © 2010 Ryan P. Murphy
64
Which container below has the lowest air pressure if the balloons are similar? Copyright © 2010 Ryan P. Murphy
65
Answer: The one on the right because the volume of the gas in the balloon is more so it must have less pressure acting on it. Copyright © 2010 Ryan P. Murphy
66
The container on the left must have higher air pressure because the air pressure is decreasing the volume of the gas in the balloon. Copyright © 2010 Ryan P. Murphy

Activity! Syringes (Opposite) How does this represent Boyles Law? Answer: As you depress the plunger, you increase pressure and the volume of the gas is decreased. Please determine how many milliliters you were able to compress the gas inside using the numbers on the syringe. Answer: You should be able to compress the gas to about 50% of it’s starting volume by hand and then it gets difficult.

As you inhale, your diaphragm flattens out allowing your chest to expand and allows more air to flow into your lungs.
98
–Air pressure decrease, air then rushes into your lungs.
99
As you exhale, your diaphragm relaxes to a normal state. Space in chest decreases.
100
–Air pressure increases, air then rushes out of your lungs.

Answer: –Your body heat warms the fluid in the abdomen. Copyright © 2010 Ryan P. Murphy
137
Answer: –The heat increases the vapor pressure in the abdomen relative to the head (the reverse of what happens when you wet the head). Copyright © 2010 Ryan P. Murphy
138
Answer: –The fluid rises into the head in response to the pressure difference (moving from high pressure to low pressure). Copyright © 2010 Ryan P. Murphy
