682mL
Explanation:
Given parameters:
Initial volume of air = 600mL
Initial temperature = 20°C
Final temperature = 60°C
Unknown:
Final volume = ?
Solution:
To solve this problem, we apply Charles's law';
Charles's law states that "at constant pressure, the volume of a given mass of gas is directly proportional to its temperature. "
Mathematically;

V₁ is the initial volume of air
T₁ is the initial temperature of air
V₂ is the final volume of air
T₂ is the final temperature of air
To proceed in solving this problem, we need to convert the given temperature to Kelvin;
T K = 273 + T°C
T₁ = 273 + 20 = 293K
T₂ = 273 + 60 = 333K
now input the parameters;

V₂ = 682mL

Answer: Some natural disasters include: tornados, hailstorms, hurricanes, wild fires, flash floods, tsunamis, and earthquakes.
To calculate the concentration of the base based on the titration, the concept used is the equal of number of equivalence of the acid used to that of the base. From this,
Na x Va = Nb x Vb
For HBr and KOH, molarity is equal to normality. Substituting the known values,
(0.75 M) x (22.6 mL - 0 mL) = Nb x (37.5 mL - 0.5 mL)
Nb = 0.46 N
Mb = 0.46 M
Thus, the concentration of the base is approximately 0.46 M.
