# The ideal gas law best describes the properties of which of the following gases

## What is the properties of ideal gas?

The properties of an ideal gas are: An ideal gas consists of a large number of identical molecules. The volume occupied by the molecules themselves is negligible compared to the volume occupied by the gas. The molecules obey Newton’s laws of motion, and they move in random motion.

## What does ideal gas law describe?

the law that the product of the pressure and the volume of one gram molecule of an ideal gas is equal to the product of the absolute temperature of the gas and the universal gas constant.

## What four properties of a gas does the ideal gas law relate?

Ideal gas, or perfect gas, is the theoretical substance that helps establish the relationship of four gas variables, pressure (P), volume(V), the amount of gas(n)and temperature(T). It has characters described as follow: The particles in the gas are extremely small, so the gas does not occupy any spaces.

## What are the properties of an ideal gas and how are they different from the properties of a real gas?

Because the molecules of an ideal gas are assumed to have zero volume, the volume available to them for motion is always the same as the volume of the container. In contrast, the molecules of a real gas have small but measurable volumes.

## What are the 5 properties of gases?

What Are Five Properties of Gases?

• Low Density. Gases contain scattered molecules that are dispersed across a given volume and are therefore less dense than in their solid or liquid states. …
• Indefinite Shape or Volume. Gases have no definite shape or volume. …
• Compressibility and Expandability. …
• Diffusivity. …
• Pressure.

## What is an ideal gas quizlet?

Ideal gas. a hypothetical gas consisting of identical particles of zero volume with no intermolecular forces undergoing perfectly elastic collisions.

## Why is it called ideal gas law?

An ideal gas is a gas that conforms, in physical behaviour, to a particular, idealized relation between pressure, volume, and temperature called the ideal gas law. … A gas does not obey the equation when conditions are such that the gas, or any of the component gases in a mixture, is near its condensation point.

## What is a real gas and an ideal gas?

An ideal gas is one that follows the gas laws at all conditions of temperature and pressure. To do so, the gas would need to completely abide by the kinetic-molecular theory. A real gas is a gas that does not behave according to the assumptions of the kinetic-molecular theory. …

## What is PV nRT used for?

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. Or you could think about the problem a bit and use PV=nRT.

## What are different gas laws?

The Gas Laws: Pressure Volume Temperature Relationships

• Boyle’s Law: The Pressure-Volume Law.
• Charles’ Law: The Temperature-Volume Law.
• Gay-Lussac’s Law: The Pressure Temperature Law.
• The Combined Gas Law.

## How is ideal gas law used in everyday life?

In Real Life

For example, if an engineer has to store 600g of oxygen in a container and that oxygen needs to be kept at a pressure of 1 atm and a temperature of 125 degrees Fahrenheit, the Ideal Gas Law is used to figure out what volume of a container needs to be built.

## What are the six gas laws?

Gas Laws: Boyle’s Law, Charle’s Law, Gay-Lussac’s Law, Avogadro’s Law.

## Is air an ideal gas?

Actually there is no “real” gas that is truly an ideal gas. An Ideal gas is a theoretical concept which has single points moving randomly with perfectly elastic collisions. At STP (Standard Temperature and Pressure) air and most pure gasses will behave closely enough to an ideal gas that the ideal gas law can be used.

## Which gas deviates most from ideal behavior?

It is also good to know that ideal gas law assumes that the gas molecules have negligible/no size. Keeping that in mind, Xe is the largest of the bunch, and therefore is expected to have the greatest deviation of the ideal gas when under high pressure or low temperature.
