Question

how easy is it to breathe through a straw? when you breathe deeply, you pull in 4.0 l of air in about 3.0 s. this requires a pressure difference of about 4.0 kpa between the air in your lungs and the outside air.

Answer 1

Breathing through a straw can be more difficult due to the smaller airway and potentially higher resistance. While it is possible, it may not provide enough air for deep breaths.

Step-by-step explanation:

When you breathe deeply, you pull in 4.0 L of air in about 3.0 s, which requires a pressure difference of about 4.0 kPa between the air in your lungs and the outside air. Breathing through a straw can be more difficult because it creates a smaller airway, resulting in a higher velocity of air and potentially higher resistance. While it is possible to breathe through a straw, it would require more effort and may not provide enough air for deep breaths.
