# Frequent question: What is inversely proportional to the number of moles?

Contents

## What is directly proportional to the number of moles?

At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas. At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas.

## What is moles inversely related to?

a. the volume of a gas is inversely related to the number of moles at constant temperature and pressure.

## Why is the number of moles directly proportional to volume?

Avogadro’s law states that “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.” For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

## What does inversely proportional mean?

If one value is inversely proportional to another then it is written using the proportionality symbol in a different way. Inverse proportion occurs when one value increases and the other decreases. For example, more workers on a job would reduce the time to complete the task. They are inversely proportional.

## Is T and V inversely or directly proportional?

The ideal gas law (PV = nRT) states that pressure P is directly proportional to (absolute) temperature T, when volume V remains constant, and is inversely proportional to volume, when temperature remains constant.

## Are P and V inversely proportional?

The law itself can be stated as follows: for a fixed amount of an ideal gas kept at a fixed temperature, P (pressure) and V (volume) are inversely proportional—that is, when one doubles, the other is reduced by half.

## Which of the following pairs of variables are inversely proportional?

Boyle’s law states that pressure (P) and volume (V) are inversely proportional. Charles’ law states that volume (V) and temperature (T) are directly proportional.

## What variables are inversely proportional and what are directly proportional?

Two variables say x and y, which are in inversely proportion relation are represented as x ∝ 1/y or x ∝ y1. Directly proportional and inversely proportional are opposite relations in comparison to one another.

## Are pressure and temperature inversely proportional?

Pressure is inversely proportional to volume when the temperature is held constant for a given amount of gas. It is also known as Boyle’s law. Pressure is directly proportional to the temperature when the volume is held constant for a given amount of gas. It is also known as Gay-Lussac law.

## Is volume directly or inversely proportional to molarity?

A plot of the effect of temperature on the volume of a gas at constant pressure shows that the volume of a gas is directly proportional to the number of moles of that gas.
