the air in the atmoshere in your region.
humidity
temperature
Temperature is the primary factor that affects the amount of water air can hold. Warmer air can hold more water vapor than cooler air. The relationship between temperature and water vapor capacity is known as the Clausius-Clapeyron equation.
your mom 80% hahaahha
A spirometer measures the amount of air in lungs
any amount ranging from none to as much as your lungs can hold.
Also known as Total Lung Capacity- the maximum amount of air your lungs can hold if you forcefully inhale.
It affects the lungs and the bronchi (the tubes that allow air into the lungs).
I suggest that you look into peak flow and try your own, if not .... Peak flow is where you breathe into a device specially designed to measure the amount of air your lungs and how much it can obtain as everybody has a different maximum level of air (oxygen) they can get in your lungs.

Lung capacity or lung volume is the amount of air a person's lungs can hold. The average human's lungs hold 6 liters of air. Lung volume can change depending on one's altitude, age, gender, height, and activities (including sports, singing, playing woodwind instruments, etc.) among others.
