Final answer:

When a fixed-width air column is warmed, the molecules move faster and spread farther apart, decreasing the density, and causing the column to increase in height due to Charles's law.

Step-by-step explanation:

When we warm one of two fixed-width air columns with the same amount of air pressure, the molecules move faster and spread farther apart, making the air become less dense. Consequently, the warmed column will increase in height. This occurrence is well-explained by Charles's law, which states that the volume of a gas increases with temperature if the pressure is constant, leading to a decrease in density. As the density decreases, air becomes more buoyant and rises, which is why the column of warmer air increases in height.
