# What happens to the volume of gas if the number of moles is doubled?

Contents

1 Answer. According to Avogadro’s law, as the number of moles of gas increases the volume also increases.

## What happens to the volume of a gas when you double the number of moles of gas while keeping the temperature and pressure constant group of answer choices?

Le Chatelier’s Principle states that: a) When a system at equilibrium is disturbed , a new equilibrium constant is established. … What happens to the volume of gas when you double the number of moles of gas while keeping the temperature and pressure constant? a) the volume decreases, but more information is needed.

## What will happen to the volume if the number of moles of a gas is decreased at constant temperature and pressure?

What will happen to the volume if the number of moles of a gas is decreased at constant temperature and pressure? … The volume will remain the same.

## What is the relationship between volume and number of moles?

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. This is stated as Avogadro’s law.

## What happens to the volume of a gas when the amount of the gas doubles and all other variables are constant?

For a fixed mass of gas at constant temperature, the volume is inversely proportional to the pressure. That means that, for example, if you double the pressure, you will halve the volume. If you increase the pressure 10 times, the volume will decrease 10 times.

## What is the relationship between volume and pressure?

The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle’s law). Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules (Avogadro’s law).

## What happens to volume when moles increase?

1 Answer. According to Avogadro’s law, as the number of moles of gas increases the volume also increases.

## Why are moles and volume directly proportional?

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.

## Does temperature affect the number of moles?

1 Answer. Well, your equation contains the same number of moles either side, so temperature does not matter.

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

A law that states that at constant temperature, the volume of a fixed amount of a gas is inversely proportional to its pressure. … A law that states that at constant temperature and pressure, the volume of a sample of gas is directly proportional to the number of moles of gas in the sample.

## How do you find the number of moles when given the volume?

There are two steps: Multiply the volume by the density to get the mass. Divide the mass by the molar mass to get the number of moles.

## How do you find moles with pressure and volume?

Multiply the volume and pressure and divide the product by the temperature and the molar gas constant to calculate moles of the hydrogen gas. In the example, the amount of hydrogen is 202,650 x 0.025 / 293.15 x 8.314472 = 2.078 moles.

## What is the result of increasing the volume of a gas?

If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases. … Gay Lussac’s Law – states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.

## Does increasing temperature increase volume?

The volume of the gas increases as the temperature increases. As temperature increases, the molecules of the gas have more kinetic energy. They strike the surface of the container with more force. If the container can expand, then the volume increases until the pressure returns to its original value.

## What happens to volume when pressure increases?

Boyle found that when the pressure of gas at a constant temperature is increased, the volume of the gas decreases. … this relationship between pressure and volume is called Boyle’s law. So, at constant temperature, the answer to your answer is: the volume decreases in the same ratio as the ratio of pressure increases.
