At what temperature does a real gas obey the ideal gas laws over a wide range of pressure?

Answer 1

Real gases behave most like ideal gases at high temperatures and low pressures.

CASE 1 :- (At Higher Temperatures)

when the temperature is high the kinetic energy of molecules increases and the intermolecular attractions among the atoms decreases.

The volume of the gas molecules become negligible compared to volume of the vessel. therefore the real gases act like ideal At Higher Temperatures.

CASE 2 :- (At Lower Temperatures)

At low temperatures volume of the container is larger. therefore intermolecular attractive forces are negligible and the volume of the particles also become negligible compared with the volume of the vessel.

therefore the real gases act like ideal At Lower Temperatures.

Answer 2

I believe that at conditions of high temperature and low pressure then gasses tend to behave more like an ideal gas. Only at lower temperatures, high pressures to the 'messy' degrees of freedom manifest themselves in molecular interactions. But at low pressure and high temperatures there are fewer molecular degrees of freedom, and so the gas becomes 'less complex' and more like the ideal gas. However, once the gas starts to become a plasma--then electromagnetic effects start to play a big role.

Answer 3

kinetic postulates gas ,the gas molecule has no attraction .at low pressure and high temperature the volume of the gas is very high .so that the kinetic energy is very high.this condition the molecule can not attrac each other.and they behave like a ideal gas.

Answer 4

Real gases approach ideal behavior at high temperature and low pressure. In this Condition gases occupy a large volume and molecules are far apart so volume of gas molecules are negligible and intermolecular force of attraction (responsible for non ideal behavior) become low. So gases approach ideal behavior.

Answer 5

A real gas behaves like an ideal gas at high temperatures and low pressures. Typically, temperatures above 1000 K and pressures below 1 atm are where real gases start to closely follow ideal gas behavior.

Answer 6

At very high temperatures, most gases obey the ideal gas law.

that temperature is called boyle temperature

Answer 7

A real gas differs from an ideal gas at all temperatures, but the difference is greatest at high pressures and low temperatures.

Answer 8

A real gas differ from an ideal gas at any temperature and pressure.

Answer 9

High Tempature and Low Pressure
