Answer:
<em>56.4 m</em>
<em></em>
Explanation:
volume increases by factor of 6, i.e 
= 6
Initial temperature T1 at bottom of lake = 5.24°C = 278.24 K
Final temperature T2 at top of lake = 18.73°C = 291.73 K
NB to change temperature from °C to K we add 273
Final pressure P2 at the top of the lake = 0.973 atm
Initial pressure P1 at bottom of lake = ?
Using the equation of an ideal gas
= 
P1 = 
= 
P1 = 5.57 atm
5.57 atm = 5.57 x 101325 = 564380.25 Pa
Density Ρ of lake = 1.02 g/
= 1020 kg/
acceleration due to gravity g = 9.81 
Pressure at lake bottom = pgd
where d is the depth of the lake
564380.25 = 1020 x 9.81 x d
d = 
= <em>56.4 m</em>

A. Because the chemicals in the battery are being converted to light and heat energy from the bulb!
The answer is: b. Safety glasses and acid-resistant gloves.
Battery acid (sulfuric acid) has pH = 0.
Sulfuric acid (H₂SO₄) is a strong acid, it means that the solution of sufuric acid is more acidic (pH<7) than water (pH = 7).
Chemical dissociation of sulfuric acid in water:
H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq).
Sulfuric acid can come in contact with eyes and hands, so it is important to wear safety glasses and acid-resistant gloves.
