Consider a cylinder (of height 10m) full of water exposed to air. average velocity of air: 3 m/s density of air: 1.3 kg/m3 viscosity of air: 2 x 10-5 kg/m-s diffusivity of water vapor in air: 8 x 10-6 m2/s diameter of cylinder: 1 m temperature: 298 k saturated vapor pressure of water at 298 k: 23 mm hg relative humidity of ambient air: 50% assume mass transfer correlation for flat plate boundary layer theory nsh = 0.664 (nre)0.5 (nsc)0.33 i. what is the rate of water vapor evaporation in g/min? ii. will this flux be constant or will it change? if so, write the equation for the flux as a function of time.

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

the answer is c
