# What is the ideal gas law used for

## Why is the ideal gas law useful?

The ideal gas equation enables us to examine the relationship between the non-constant properties of ideal gases (n, P, V, T) as long as three of these properties remain fixed. … The ideal gas equation is a valuable tool that can give a very good approximation of gases at high temperatures and low pressures.

## What does the 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 does the ideal gas law assume?

The Ideal Gas Law assumes several factors about the molecules of gas. The volume of the molecules is considered negligible compared to the volume of the container in which they are held. We also assume that gas molecules move randomly, and collide in completely elastic collisions.

## How do you solve ideal gas law?

## When can you assume ideal gas?

Please notice that “Ideal Gas Law” is “ideal” because it only works when you assume the conditions are “ideal”. And well, all gases behave ideally under conditions of high temperature and low pressure. At low temperature, there are less gas molecules in a certian volume.

## What are 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.
