Answer: The total pressure of air in lungs of an individual is 760.28 mm Hg
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.

Given :  =total pressure of gases = ?
 =total pressure of gases = ?
 = partial pressure of oxygen = 100 mm Hg
 = partial pressure of oxygen = 100 mm Hg
 = partial pressure of nitrogen = 573 mm Hg
 = partial pressure of nitrogen = 573 mm Hg
 = partial pressure of Carbon dioxide = 0.053 atm = 40.28 mm Hg(1 atm = 760 mmHg)
 = partial pressure of Carbon dioxide = 0.053 atm = 40.28 mm Hg(1 atm = 760 mmHg)
 = partial pressure of water vapor = 47 torr = 47 mm Hg  (1torr=1 mm Hg)
 = partial pressure of water vapor = 47 torr = 47 mm Hg  (1torr=1 mm Hg)
putting in the values we get:
 
 
 
 
Thus the total pressure of air in lungs of an individual is 760.28 mm Hg
 
        
             
        
        
        
Answer:
state of matter
Explanation:
Because there are three state of matter namely:liquid,solid and gas and oxygen is a gas.
 
        
             
        
        
        
It is a Physical property because like water it changes into a ice cube but it can be melted into water or be turned back into an ice cube.
