Draw and Dimension the Bathroom Window. To add a window to the Bathroom, we will change the current layer to window and draw a vertical 4.5 line from the endpoint of the outside of the lower right corner of the exterior wall.
Cold air is denser and heavier than warm air, so it tends to sink while warm air tends to rise. In areas where winds converge at high altitude, cold air sinks and creates a temporary buildup of air near the Earth's surface and thus a zone of high pressure. Atmospheric pressure decreases with increasing altitude, so high pressure is actually a relative term; generally, weather forecasters use this to mean high relative to normal atmospheric pressure at that altitude.
But, the water that makes the air humid isn't liquid. It's water vapor, which is a gas that is lighter than nitrogen or oxygen. (Related: Understanding water in the atmosphere). Compared to the differences made by temperature and air pressure, humidity has a small effect on the air's density. But, humid air is lighter than dry air at the same temperature and pressure.
