Droplets may fall down when clouds are heavy。 31. 水循环的四个阶段依次是:水变成水蒸气(Changing into Vapor)、水蒸气变成云(Turning into Clouds)、水滴落回地面(Falling as Rain or Snow)、水流回海洋(Going back to the Oceans)。因此,正确顺序是 C. ③①②④。 32. 文章指出水循环确保了全球水...
In the process of cloud formation, the change from water vapor to liquid droplets is called ___. A. melting B. freezing C. condensation D. sublimation 相关知识点: 试题来源: 解析 C。解析:在云形成过程中,从水蒸气到液态小水滴的转变被称为凝结(condensation)。A选项“melting”(融化)是指固态...
SOLLER,1962: Water-vapor exchange between a water droplet and its environment. J. Geophys. Res., 67, 2761-2766.Friedman I., Machta L., and Soller R. (1962) Water-vapor exchange between a water droplet and its environment [J]. J. Geophys. Res. 67, 2761-2766....
As a result, the coldest areas, such as arctic regions and mountain tops, have the lowest vapor concentrations because the water droplets have little energy to evaporate. A phase diagram is a core tool used in physical chemistry to understand the correlation between temperature, pressure, and ...
hence is less dense. Due to the significant difference in density,buoyancydrives humid air higher. As altitude increases, air pressure decreases and the temperature drops. The lower temperature causes water vapor to condense into tiny liquid waterdropletswhich are heavier than the air, and fall unl...
About a third of the reviewed articleswere relevant to vapor or gas ignition scenarios. The authors cited four references werc thepresence of water droplets actually increased the intensitv of a deflagration reaction. In eachcasc, one or more of the following was observed: ( I ) increased ...
is condensation.Clouds can be a mass of waterdroplets or ice particles.When the clouds get heavy enough,the water falls back to theground in the form of rain,snow or hail.This is precipitation.Plants in our environmentcontain water in a liquid form.They release water vapor into the ...
Graupelare soft, small pellets(颗粒状物) formed when supercooled water droplets (at a temperature below 0°C) freeze onto a snow crystal, a process called riming(结晶). If the riming is particularly intense, the rimed snow crystal can grow to anappreciablesize, but remain less than 0.2 inch...
Water in three states:liquid,solid (ice),and (invisible) water vapor in the air.Clouds are accumulations of water droplets,condensed from vapor-saturated air.Water is a chemical substance with the chemical formula H2O.Its molecule contains one oxygen and two hydrogen atoms connected by covalent ...
water dropletsWater is a polar molecule and is attracted to other polar molecules. Thus, droplets, or beads, of water form on a nonpolar surface because water molecules adhere together instead of adhering to the surface. Hydrogen atoms in water molecules are attracted to regions of highelectronde...
