Answer:
158.35 K
Explanation:
Using the general gas law
P₁V₁/T₁ = P₂V₂/T₂ where P₁ = 150.4 kPa, V₁ = 12.2 L, T₁ = 22.7 °C = 273 + 22.7 = 295.7 K, P₂ = 101.3 kPa, V₂ = 9.7 L and T₂ = unknown.
Making T₂ subject of the formula, we have
T₂ = P₂V₂T₁/P₁V₁
Substituting the values of the variables into the equation, we have
T₂ = P₂V₂T₁/P₁V₁
T₂ = 101.3 kPa × 9.7 L × 295.7 K/150.4 kPa × 12.2 L
T₂ = 290,557.777 K/1,834.88
T₂ = 158.35 K
Answer:
The sole purpose is to rejuvenate the column. After long use the ions bound in the permutit column will get washed away. This can be replaced by washing the column with NaCl.
The ph level depends on temperature.
