Document Summary

Longwave from the earth: blackbody radiation curves, the role of the atmosphere and earth"s energy receipt, the heat balance, energy transfer, net radiation. This is similar to a chimney"s process of sending a hot warm level of air rises until it meets air that is like temperature. This may occur in the cities due to smog layers as the smog layer is unable to rise. Moving air: will cool at the dry adiabatic lapse rate. Dalr: gas laws pv/t=k (k being a constant, rate is 10 degrees per 10000 meters amount is 9. 8 degrees, the air dry and not saturated, this is basically a constant relationship (generally accepted actual. If condensation occurs in this moving air the will be saturated air: the air will now cool at the saturated adiabatic lapse rate salr. It is called mar moist adiabatic rate: rate is variable but less than dalr <10 degrees per a thousand meters, depends on the temperature.

A helium filled balloon with a volume of 1.00*10^3 cm^3 and temperature of 27 degrees C is placed in liquid nitrogen in an open container and cools to a temperature of 77K.Assume that helium behaves like an ideal gas at constant atmospheric pressure, find the new volume of the gas in the balloon,the change in the internal energy of the gas,the work done during the process,and the heat removed from the gas.

The arrow OA in the PV diagram shown in Figure OQ22.11 represents a reversible adiabatic expansion of an ideal gas. The same sample of gas, starting from the same state O now undergoes an adiabatic free expansion to the same final volume. What point on the diagram could represent the final state of the gas?

(a) the same point A as for the reversible expansion, (b) point B, (c) point C, (d) any of the choices, and (e) none of those choices.
