What direction does warm vapor typically move?

Warm vapor typically moves toward cold areas because it is influenced by the principle of convection. In simple terms, warmer air or vapor is lighter and less dense than cooler air. As such, warm vapor will rise, and when it comes into contact with cooler surfaces or air masses, it tends to move in the direction of the colder area to seek equilibrium. This process is driven by the natural tendency for heat to flow from warmer areas to cooler areas, attempting to balance the temperature differences. Thus, warm vapor migrating toward cold is a fundamental concept in thermodynamics and fluid dynamics.
