Which of the following can increase the amount of water vapor in the air? A. Cooling B. Heating C. Freezing D. Condensing 相关知识点: 试题来源: 解析 B。解析:加热(Heating)可以增加空气中水汽的量。因为加热会使液态水更容易蒸发变成水汽。冷却(Cooling)会使水汽凝结而减少水汽量。冻结(Freezing)是...
water-vapor is mainly controlled by the southerly monsoon,37.7% of the total water- vapor is from the south,especially in summer,the southerly water-vapor flux accounts for 55.9% of the total,and furthermore the water-vapor content in the southerly flow is more than that in the westerly ...
The meaning of WATER VAPOR is water in a vaporous form especially when below boiling temperature and diffused (as in the atmosphere).
