FAQs
Question: What is the difference between real gases and ideal gases? Answer: Real gases exhibit interactions between molecules and deviate from ideal behavior under high pressure and low temperature, while ideal gases follow the gas laws perfectly without such interactions.
Question: How does the Van der Waals equation improve our understanding of real gases? Answer: The Van der Waals equation accounts for molecular volume and intermolecular forces, providing a more accurate representation of real gas behavior compared to the ideal gas law.

Q. At which conditions do real gases behave most like ideal gases?
A.
High pressure and low temperature
B.
Low pressure and high temperature
C.
High pressure and high temperature
D.
Low pressure and low temperature
Solution
Real gases behave most like ideal gases at low pressure and high temperature, where intermolecular forces are minimized.
Correct Answer:
B
— Low pressure and high temperature
Q. What is the effect of increasing the number of gas molecules in a container at constant volume?
A.
Pressure decreases
B.
Pressure increases
C.
Temperature decreases
D.
Volume increases
Solution
Increasing the number of gas molecules in a container at constant volume increases the frequency of collisions with the walls, thus increasing pressure.
