The formula for the Ideal Gas Law is PV=nRT. Therefore, V=nRT/P. If T and P are constant and only the moles change V is entirely dependent on n. Since n is in the numerator of the equation, that means as the number of moles increase, the volume will increase too. This means V is directly proportional to n.

Q: Is the volume of a gas directly or inversely proportional to the number of moles of gas at constant temperature and pressure?

Directly proportional, at pressure and temperature constant.

Force is directly proportional to mass provided the acceleration is constant.

Various options: y is directly proportional to k, with x as the constant of proportionality; y is directly proportional to x, with k as the constant of proportionality; x is inversely proportional to k, with y as the constant of proportionality; x is directly proportional to y, with 1/k as the constant of proportionality; k is directly proportional to y, with 1/x as the constant of proportionality; and k is inversely proportional to x, with y as the constant of proportionality.

Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.

directly proportional because force=(mass)(acceleration) (f=ma)

Directly proportional: pressure and temperature (Boyle's Law and Charles's Law), inversely proportional: volume and pressure (Boyle's Law), volume and temperature (Charles's Law).

The ideal gas law:PV = nRT Any two variables on the SAME SIDE of the equation are inversely proportional. Note that "R" is a constant; so the following are inversely proportional: P and V n and T (And any two variables on OPPOSITE sides are directly proportional.)

Generally, if y increases as x increases, this is a hint that the quantity is directly proportional, and if y decreases as x increases, the relation might be inversely proportional. However, this is not always the case. x and y are directly proportional if y = kx, where k is a constant. x and y are inversely proportional if y = k/x, k is constant. This is the best way to tell whether the quantities are directly or inversely proportional.

Various options: y is directly proportional to k, with x as the constant of proportionality; y is directly proportional to x, with k as the constant of proportionality; x is inversely proportional to k, with y as the constant of proportionality; x is directly proportional to y, with 1/k as the constant of proportionality; k is directly proportional to y, with 1/x as the constant of proportionality; and k is inversely proportional to x, with y as the constant of proportionality.

Two variables, X and Y are said to be in inversely proportional is X*Y - k where k is some non-zero constant. X and Y are said to be directly proportional if X = c*Y where c is some constant.

Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.

In directly proportional the two variable vary in the same "direction". So, if one increases, the other increases.In inversely proportional, the two variable vary in opposite "directions". So, if one increases, the other decreases.

No, temperature and concentration of oxygen are not inversely proportional. Changes in temperature can affect the solubility of oxygen in water, but the relationship is not strictly inverse. The solubility of oxygen generally decreases with increasing temperature.

directly proportional to its temperature. This relationship is known as Charles's Law.

Volume is directly proportional to temperature for gases, meaning that as temperature increases, the volume of a gas will also increase. This relationship is described by Charles's Law.
