Below are sample questions representative of the exercises included on this worksheet and related 11.52 Kinetic Molecular Theory of Gases skill assessments:

Problem 1Difficulty: Mastery

Use the planned before-and-after model of a sealed can being warmed. Which explanation best combines the KMT prediction with a model limitation?

APressure must stay constant because the can volume is fixed.

BPressure falls to zero because warming removes collisions.

CPressure rises only because particles become larger, which ideal KMT assumes.

DPressure rises as particle collision effects increase, but real-gas attractions and container limits may affect exact behavior.

Solution & Explanation:In a sealed rigid container, heating increases average kinetic energy and pressure. A complete real-world model also considers deviations from ideal behavior and container safety limits.

Problem 2Difficulty: Mastery

A rigid container has pressure P at 300 K. A student says, 'If 30 degrees Celsius changes to 60 degrees Celsius, pressure should double just like 300 K to 600 K.' Which evaluation is best?

ABoth changes double absolute temperature, so both must double pressure.

BNeither change can affect pressure in a rigid container.

CThe 300 K to 600 K change doubles absolute temperature, but 30 degrees Celsius to 60 degrees Celsius does not.

DCelsius temperature is always the correct scale for KMT proportional reasoning.

Solution & Explanation:KMT pressure-temperature proportionality uses kelvins. Changing from 30 degrees Celsius to 60 degrees Celsius is about 303 K to 333 K, not a doubling of absolute temperature.

Problem 3Difficulty: Mastery

Which gas sample should behave most like an ideal gas?

AAmmonia at 230 K and 20 atm.

BHelium at 650 K and 0.5 atm.

CCarbon dioxide near its condensation temperature at 30 atm.

DWater vapor at low temperature and high pressure.

Solution & Explanation:A small, nonpolar gas at high temperature and low pressure is closest to ideal behavior. Helium under these conditions has weak attractions and particles far apart.
