How can you determine the mass volume and density of a textbook a container of milk and an air balloon?
You need to measure the mass using appropriate equipment. You can measure the volume of a textbook and a container of milk by measuring its linear dimensions and calculating the volume. It is not at all easy to measure the volume of an air balloon. You cannot use displacement of a fluid (water) because when submerged, the balloon would be experiencing water pressure and so would occupy a smaller volume. You cannot measure it by allowing the air to escape and measure that volume of air because that air will no longer be experiencing the pressure exerted by the material (rubber?) of the balloon. I have no answer to this part. Once you have the mass and volume, the density is merely mass/volume.
What are 3 factors affect air pressure?
The factors are: -The volume that the air takes up (the greater the volume the less the pressure) -The amount/number of molecules of air (the more gas the higher the pressure) -The temperature (the higher the temperature the higher the pressure) and that's it lol
What is the purpose of a flow meter?
The purpose of a flow meter is to measure the flow of either air or water. They allow one to measure the total volume of air or liquid flow and the rate of the flow.
What is the density of a half liter water bottle that masses 20g?
The idea is to divide the mass by the volume. I assume the half liter is what fits inside the bottle; in theory, the actual volume of the bottle plus the contents should be slightly more. Also, in theory you'll have to add a small amount of mass for the air inside. If the bottle is filled with air, then you'll actually get the average density of the bottle plus the air.
Is the volume of water displaced when a golf ball is dropped in a large beaker greater than the volume of the golf ball?
Yes, but only if there is air, dust and other molecular scale debris attached to the ball. In a perfect universe, where nothing but the ball enters the water, then the volume would be exactly the same as that of the sphere.
The lung volume that represents the total volume of exchangeable air is the?
The lung volume that represents the total volume of exchangeable air is the vital capacity. It is the maximum amount of air a person can exhale after taking the deepest possible inhalation.
What is the name of the volume of air that you completely exhale?
vital capacity
How is vital capacity determined?
Vital capacity is the amount of air you can breathe out after a maximum inhale. When it comes to determining vital capacity it’s basically calculated by the inspiratory reserve volume in addition to the expiratory reserve volume.
What is the lung volume that represents the total volume of exchangeable air?
vital capacity
Name and explain the volume that make up vital capacity?
The vital capacity is the maximum amount of air that a person can expel from the lungs.
Is vital capacity the greatest volume of air that can forcibly be expired in one breath?
True
The largest amount of air that can be breathed in and out in one breath is called?
The largest amount of air that can be breathed in and out in one breath is called the vital capacity.
Difine the meanings of tidal volunme and vital capacity?
Tidal volume is the amount of air that moves in and out of the lungs during normal breathing. Vital capacity is the maximum amount of air a person can exhale after taking the deepest breath possible. It is the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume.
How do you measure vital capacity?
Vital capacity is measured using a spirometer. The person takes a deep breath in and then exhales as forcefully and completely as possible into the spirometer. The spirometer records the volume of air exhaled, which is used to calculate the vital capacity.
What is the clinical significance of vital capacity?
It represents your maximum lung capacity minus the dead air space and the residual volume. It is the amount of air you can move after taking in the biggest breath you can and then blowing out all the air you can exhale. Some diseases reduce the vital capacity of the lungs and make it difficult to breathe.
What is the equation for tidal volume?
Amount of air that is inhaled or exhaled with normal breath. NORMAL VALUE IS 500ml Vital capacity= IRV+ TV+ ERV TV = Vital capacity- (IRV+ERV) I hope, this is it!!
Why should you wear a nose peg when using spirometer to measure your tidal volume and vital capacity?
Because a nose peg will prevent any air from accidentally escaping through your nasal passages, assuring an accurate tidal volume and vital capacity result when you blow air out forcefully from your mouth into the spirometer.
