What is the formula for volume if given density?
The formula for mass if density is not given is mass=volume/power
What would happen if you pack more mass into a certain volume?
this is the concept of density. the more mass contained in a certain volume, the denser the material (1 cubic cm of lead is denser than 1 cubic cm of water) Density=mass/volume
You put more efforts when you exhale air or when you inhale the air?
During normal breathing at rest, inspiration is an active process while expiration is passive. So under normal conditions, you put more energy into inspiration than expiration.
What cause the difference in the amount of air you inhale and exhale?
Lungs alveoli has very large surface area, about 100 square meters. So air is fully saturated with water vapor and so it is more in amount.
If you add water to sand does the volume density and mass change?
Yes because the sand adds more mass to the mass of the water, therefore the density and volume also change
What is the difference between the air you inhale than the air you exhale?
the difference between inhale and exhale is when you inhale you get more oxygenthan you exhale
How do you use an inspirometer?
inhale slowly through the hose then exhale, DO NOT force yourself to inhale more than your lungs are comfortable with, its a lot like smoking except you exhale immediately like a breath
Why is there less oxygen in exhaled air then inhaled?
You breathe air for the oxygen and hydrogen, when you inhale chemical changes begin and you take in the oxygen and exhale carbon dioxide which things like plants then use to make more oxygen. You are not exhaling the same compound.
Why humans exhale more water vapour than they inspire?
Humans exhale more water vapour than they inhale because water vapour is a product of respiration which means that your body creates it so has more to get rid of.
Which two gases are which you exhale more than inhale?
Carbon dioxide and water vapour.
What does the contraction of the diaphragm cause?
It allows you to breath or more precisely exhale. When the muscle is relaxed your lungs expand and you inhale.
Does a paper bag help with hyperventilation?
Yes, paper bag is long years ago use for hyperventalation the logic here is that you rebreath the air you exhale. This helps the you to inhale more CO2 (air that you exhale) back into your bloodstreams. And this works.
How is mass per volume different than volume per mass?
One is the reciprocal of the other. It is more common to use "mass per volume", but in theory you could use either. If object "A" has more mass per volume than object "B", then object "B" will have more volume per mass than object "A".
What layer of muscles move up and down when you breath?
The diaphragm is a muscle that moves or pushes up your lung when you exhale and down when you inhale in order to allow more space for oxygen to fill your lung. Also, your chest expands as you breath in and relax as you exhale.
How can a small object be more dense if it does not have the most mass?
You seem to be thinking that density is the same as mass, or proportional to mass. That is not the case. Density is mass divided by volume. For example, two objects of the same material have the same density. The larger object will have more mass (in the numerator), but it will also have more volume (in the denominator).
What happens when the diaphragm and the rib cage muscles relax?
The diaphragm relaxes during EXHALATION. Your diaphragm flattens when you inhale, creating more space for the lungs to take in more air.
Why ribs are attached to the sternum by cartilage?
If the ribs were not attached to the sternum by cartilage (which is flexible), it would be more difficult to breathe, because as you inhale and exhale the chest needs to be able to flex.
