15 Questions
What is a key characteristic of ideal gas molecules?
They occupy significant space individually
Which of the following best describes the energy behavior of molecules in ideal gases?
Energy is conserved during elastic collisions
What distinguishes ideal gases from real gases in terms of intermolecular forces?
Ideal gases have strong intermolecular attractions
Which of the following properties are governed by the ideal gas law?
Volume, temperature, and pressure
Why must temperature always be in Kelvins when using the ideal gas law formula?
Because zero Kelvin represents absolute zero
What aspect of gas particles is taken into account by adjusting the volume in the Van Der Waals Equation?
Molecular size
Which constant in the Van Der Waals Equation describes the volume of 1 mole of gas?
b
What does the constant 'a' represent in the Van Der Waals Equation?
Inter-particle attraction
In the comparison between real and ideal gases, what type of collisions do ideal gas particles exhibit?
Elastic
What distinguishes a real gas from an ideal gas according to the text?
The occupation of volume by individual molecules
What is the main reason why the ideal gas law fails at high pressures and low temperatures?
The intermolecular forces become too significant to neglect.
Which scientist is credited with first recognizing the ideal gas assumptions?
Johannes Van der Waals
What is a key difference between real gases and ideal gases?
Real gases have inelastic collisions, while ideal gases have elastic collisions.
Under what conditions is the ideal gas law applicable?
When gas density is low and inter-particle attractions are negligible.
Why do high pressure and low temperature cause deviations from the ideal gas law?
Molecules experience significant intermolecular interactions.
Learn about the ideal gas behavior where gas molecules do not lose energy upon collisions and follow the ideal gas law. Understand how ideal gases exhibit elastic collisions and no resistance to flow due to their theoretical nature.
