It is found that scuba diver’s can safely ascend up to 52.53 ft without Breathing out.
By what factor would a scuba diver’s lungs expand if she ascended rapidly to the surface from a depth of 125 ft without inhaling or exhaling then
=patm+
= 101325+ρ
It is given that height is 125ft. Put the value of h in above formula:
h1 =125ft=38.1m
ρ=1.04g/mL=1040kg/
g=9.81
=101325Pa+388711.44
=490036.44Pa
=p atm =101325Pa
It is known that volume and pressure can be expressed as:
V*P=const.
where, V is volume and P is pressure.
Now,
=
=
=490036.44/101325
=4.84
Assume constant temperature
d of seawater = 1.04 g/mL; d of Hg = 13.5 g/mL.
now =p atm+
=490036.44Pa
V*p=const
where, V is volume and P is pressure.
Now,
=
=
=490036.44/X
=490036.44pa/(V2/V1) =326690.96Pa
=patm +p
=101325Pa+ρ
326690.96Pa=101325Pa+ρ
ρgh1 =151987.5-101325=225365.96Pa
ρ=1,04g/mL=1040kg/m3
g=9.81
=225365.96/ρ∗g
=225365.96 / 1040∗9.81
=22.09m= 72.47ft
ΔH=
=125-72.47
=52.53ft
So she can safely ascend up to 52.53 ft without Breathing out

The correct answer choice is CO₂ (B)
Rainwater naturally contains acids derived from carbon dioxide in the air and reacts with water vapor to form weak acids
H₂O + CO₂ ---> H₂CO₃
<h3><em>Further Explanation</em></h3>Rainwater can cause damage to buildings, animals or plants due to acid rain
Acid rain occurs because other gases in the air mix with toxic gases to form acids
Rainwater naturally contains acids derived from carbon dioxide in the air and reacts with water vapor to form weak acids
H₂O + CO₂ ---> H₂CO₃
However, due to exhaust gases from industry, motor vehicles, or power plants that use fossil fuels containing sulfur to produce sulfur dioxide gas which will produce sulfuric acid
Sulfur combustion from fossil fuels
S + O₂ ----> SO₂
SO₂ produced from this exhaust gas reacts with O₂ oxygen which oxidizes SO₂ to SO₃
SO₂ + O₂ ----> SO₃
SO3 formed reacts with water vapor in the air to produce sulfuric acid as acid rain
SO₃ + H₂O ---> H₂SO₄
To reduce the pollution from this fossil fuel, various studies are now carried out as substitute energy that is more environmentally friendly such as solar energy and so on
