Doing which of the following to a sample of gas in a container would most likely make the gas molecules move faster?

Rationale

Heating a sample of gas in a container would most likely make the gas molecules move faster.

Heating increases the kinetic energy of gas molecules, causing them to move more rapidly. As temperature rises, the average energy of the molecules increases, leading to faster molecular motion and greater pressure exerted on the container walls.

A (Condensing) YOUR ANSWER

Condensing a gas involves reducing its volume and increasing pressure, often leading to phase change into a liquid. This process typically decreases the kinetic energy of the gas molecules, causing them to move slower rather than faster.

B (Cooling) YOUR ANSWER

Cooling a gas reduces its temperature and, subsequently, the kinetic energy of its molecules. As the temperature drops, gas molecules move more slowly, resulting in decreased molecular motion and pressure within the container.

C (Freezing) YOUR ANSWER

Freezing involves lowering the temperature of a substance below its freezing point, transitioning it from a gas to a solid state. In this state, molecular movement is significantly restricted, as the molecules are fixed in place within a solid lattice structure, leading to minimal motion.

D (Heating) CORRECT

Heating a gas increases the average kinetic energy of its molecules, allowing them to move more vigorously. This results in faster molecular motion, which is associated with higher temperatures and increased pressure within the container.

Conclusion

The relationship between temperature and molecular motion in gases is a fundamental principle of thermodynamics. Among the given options, heating is the only action that increases the kinetic energy of gas molecules, resulting in faster movement. Cooling, condensing, and freezing all lead to reduced molecular motion, showcasing the direct impact of temperature on gas behavior.
