# Under what conditions do real gas behaves like an ideal gas?

## Under what conditions do real gases most closely approximate the behavior of ideal gases?

Gases most closely approximate ideal gas behavior at high temperatures and low pressures.

## In which condition can real gas closely obey the ideal gas equation?

Real gases obey ideal gas laws at low pressure and high temperature because at low pressure the number of molecules per unit volume is less so attractive force between them is negligible.

## Under which conditions does a real gas behave most like an ideal gas quizlet?

Real gases behave like ideal gases when they are under high pressure and are at low temperatures.

## Under which of the following sets of conditions does a real gas behave most like an ideal gas and for which conditions is a real gas expected to deviate from ideal behavior?

Solution : (d) A real gas can behave like an ideal gas at low pressure and high temperature.

## Which of the following gases behaves most like an ideal gas?

The real gas that acts most like an ideal gas is helium. This is because helium, unlike most gases, exists as a single atom, which makes the van der Waals dispersion forces as low as possible.

## Under which conditions of temperature and pressure does a real gas behave most like an ideal gas quizlet?

Under which conditions does a real gas behave most like an ideal gas? Low pressure and high temperature.

## Why do real gases behave like ideal gases?

At 'higher temperature' and 'lower pressure', a gas behaves like an ideal gas, as the potential energy due to intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.

## What are ideal gas conditions?

For a gas to be “ideal” there are four governing assumptions: The gas particles have negligible volume. The gas particles are equally sized and do not have intermolecular forces (attraction or repulsion) with other gas particles. The gas particles move randomly in agreement with Newton's Laws of Motion.

## Under what condition does a real gas display the most ideal behavior?

Gases are most ideal at high temperature and low pressure.

## What are the conditions for ideal gases?
