Question

What is the relationship between the volume and the number of moles at constant temperature and pressure?a. direct squareb. inverse squarec. directly proportionald. inversely proportional

Answer 1

ANSWER:

c. directly proportional

STEP-BY-STEP EXPLANATION:

We have that the equation of the ideal gases is the following:

$PV=nRT$

Since pressure and temperature are constant, we would be left with:

$\begin{gathered} k_1V=k_2n \\ \\ V\text{ }\alpha\text{ }n \end{gathered}$

Which means that the relationship is directly proportional. So the correct answer is c. directly proportional
