B - The reactants are the starting substances and the products are the end substances.
Answer:
P₂ = 13.9 atm (3 sig. figs.)
Explanation:
The pressure (P), Volume (V) relationship with Temperature (T) & mass (n) held constant is an inverse proportionality. That is Boyles Law ...
P ∝ 1/V => P = k/V => k = P·V
For two pressure-volume conditions, the proportionality constant (k) remains constant where k₁ = k₂ and P₁·V₁ = P₂·V₂ => P₂ = P₁·V₁/V₂
Given:
P₁ = 1.31 atm.
V₁ = 5.51 L
P₂ = ?
V₂ = 0.520 L
V₂ = (1.31 atm)(5.51L)/(0.520L) = 13.88096154 atm (calc. ans.) = 13.9 atm (3 sig. figs.)
The answer is B. Molecules move more quickly as temperature increases.
When Allmond molecular motion stops, that is considered absolute zero. That does not mean that it cannot get colder, disapproving A.
C is just wrong.
D says when molecular motion stops the temperature STARTS to decrease, it was decreasing before it got there.
FALSE
There are other limiting factors like lack of space, diseases, and com petition.
