Your lungs expand when you inhale.
You can measure your volume by measuring the difference in depth of a known pool of water with you in it and with you out if it. Holding your breath is going to change your volume, so you might need to consider that as well.
Minute volume is calculated by multiplying tidal volume by breath rate. Tidal volume is the amount of air inhaled or exhaled in one breath, while breath rate is the number of breaths taken per minute. By multiplying tidal volume and breath rate, you can determine the amount of air exchanged in one minute.
A phase change occur, energy is absorbed, water volume decrease.
No. Breathalyzers measure the amount of alcohol per unit volume. Breath strips only change the smell of the air, not the alcohol content.

sometimes the wiff of a zebras foot can occur.
No, expiratory reserve volume (ERV) is not the amount of air that moves in or out of the lungs during a normal breath. Instead, ERV is the additional volume of air that can be forcibly exhaled after a normal expiration. The amount of air that moves in or out during a normal breath is known as tidal volume.
Percentage change in volume= Change in volume/intial volume X 100
Volume is a physical quantity not a change. However CHANGE in volume is a physical change.
the volume of a steel sheet plate is < length *breath *height >
Yes it does change because its mass does not change but its volume does. When it is compressed the density will increase because its volume does. When it is attenuated will decrease because the volume does. Density is mass over volume. Remember: it only works because its mass stays the same and the volume changes.
I use it to breath by changing the volume of my chest.
