Ideal Gas Problems

What does the ideal gas law assume about gas particles?

• They have a fixed volume.

• They have no volume and no intermolecular forces.

• They are always at high pressure.

• They are always at low temperature.

Which scientist is known for unifying the relationships between pressure, volume, temperature, and amount of gas?

• Boyle

• Charles

• Avogadro

• Mendeleev

Why is standard temperature and pressure (STP) important in experiments?

• It increases the accuracy of measurements.

• It provides a common baseline for comparison.

• It reduces the need for calculations.

• It allows for unique experimental conditions.

What is the subtle difference between 100 kPa and 1 atm in terms of gas volume calculations?

• 1 atm is 101.325 kPa, slightly altering gas volume calculations.

• 1 atm is equal to 100 kPa.

• 100 kPa and 1 atm have no effect on gas volume.

• 100 kPa is greater than 1 atm.

What was a major safety risk associated with the Hindenburg's use of hydrogen gas?

• It was difficult to produce.

• It was too heavy to lift.

• It was too expensive.

• It was highly flammable.

What does the fire piston experiment demonstrate about gas laws?

• Gas expansion decreases temperature.

• Gas expansion increases pressure.

• Rapid compression increases temperature.

• Gas compression has no effect on temperature.

How do ideal gas law calculations help in real-world applications?

• They are not applicable to real gases.

• They are only used in historical technology analysis.

• They help quantify phenomena and predict gas behavior.

• They are only theoretical and have no practical use.
