Water is supplied to the atmosphere by evaporation from the surface, and leaves the atmosphere via precipitation. the average amount of time a water molecule spends in the atmosphere can be derived by dividing the amount of water vapor in the atmosphere (1.1x1016 by the globally-averaged rate of precipitation to the earth’s surface of 3.1 mm −1 . using these data, calculate how many days, on average, a water molecule spend in the atmosphere before it precipitates out.

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
