If the volume is doubled at constant pressure, the temperature will be: unchanged halved doubled unable to be determined without more information 2. An ideal gas is sealed in a container at constant volume. If the temperature T is increased to 4T, the pressure will be: unchanged increased to 4P decreased by 4P unable to be determined without more information 3. A sample of an ideal gas is held at constant temperature. If the pressure is decreased to 1/2 P, the volume will be: increased to 2V decreased to 1/2 V unchanged unchanged 4. A cylinder has 2 moles of ideal gas at a constant volume and pressure. Adding 2 more moles of gas makes the temperature unchanged doubled halved halved 5. The temperature of an ideal gas is increased from 300K to 1200K. The kinetic energy: remains constant increases by a factor of 2 increases by a factor of 4 increases by a factor of 8 increases by a factor of 16 6. P, V, M, T, and R are pressure, volume, molar mass, temperature and gas constant, then density of an ideal gas is: RT/PM M/V P/RT PM/RT 7. The temperature of an ideal gas is increased from 300K to 600K. The average molecular speed of the gas molecules increases 4 times increases 2 times remains the same decreases 2 times decreases 4 times 8. A sealed container has 0.10 moles of nitrogen gas and 0.20 moles of oxygen gas at constant temperature. Which is true? The molecular masses of the two gases are the same. The partial pressures of the two gases are the same. The average molecular speeds of th two gases are the same. The average kinetic energies of the gases are the same. 9. A mixture of CO2, O2, and He is held at constant temperature. Which molecule has the highest average molecular speed? carbon dioxde oxygen helium all three gases have the same average molecular speed 10. Which of the following conditions would cause the ideal gas laws to fail? high pressure high temperature high volume Ideal Gas Law Quiz You got: % Correct. Not an Ideal Score on the Ideal Gas Quiz Paul Taylor / Getty Images Nice try! You made it to the end of the quiz, but it looks like you could use more practice with the ideal gas law before mastering it. First, review the equation for the ideal gas law and then see how it's applied in a practice problem. Ready for another chemistry quiz? See if you know the pH of common household chemicals.
