Pressure drops occur when airflow is restricted by pipes or fittings. Imagine trying to breathe through a drinking straw—it’s much harder to get a large volume of air through that small opening. The reason? The smaller the diameter, the faster the air must move to maintain the same airf...
Relief rain, sometimes referred to as orographic rain, is caused when air is forced to cool as it rises over a physical obstruction, such as a mountain range, or big hills.地形雨的形成是当空气上升遇到物理障碍(如山脉或大山)时被迫冷却，然后就会产生这种现象。As the warm air rises over the ...
Why does gravity have pull but no push? Under what conditions can a balloon become charged and not charged? As a helium balloon rises up in the air, work is done on it against the force of gravity. What is doing the work? What energy transfer or transformation is taking places?
