Which trophic levels have the most biomass? Which have the most energy? Why? The second law of thermodynamics requires that the primary producers have the most biomass and total energy. See:http://www.physicalgeography.net/fundamentals/9o.html

Using the first law of thermodynamics explain why the specific latent heat of vaporisation of water is greater than the specific latent heat of fusion of ice. The first law of thermodynamics (conservation of energy) has nothing to do with why vaporization requires more energy ...

earth science am i right?
am i right 19. According to the law of __________, only a worldwide flood with its vast complex of sediment-saturated currents would produce horizontal superimposed layers of materials, thus forming a great series of sedimentary strata formed in various parts of the earth. X ...

physics in a way
If you break a raw egg, why can't you put it back together? using relations to entropy and the 2nd law of termodynamics I am not certain of any physical laws that prohibit it. The 2nd law will require that energy be added in order to make up for the increased entropy when ...

what is the difference between a theory and hypothesis? I got this off another site i hope it helps.. Scientific Laws, Hypotheses, and Theories Lay people often misinterpret the language used by scientists. And for that reason, they sometimes draw the wrong conclusions as to ...

A gas expands from a volume of 2.00m^3 to 6.00m^3 and does 6912 joules of work against a constant outside pressure. Calculate this outside pressure in Pa. The answer is 1730 Pa, but I don't know how to get that. I honestly have no idea where to start or what formulas to use. ...

Why does water freezing not violate the second law of thermodynamics? (Hint: Think in terms of a system) The entropy of the water decreases when it freezes and goes into a more ordered crystaline state. However, heat is released to the environment in the process. If the ...

Which of these statements are in accord with the three laws of thermodynamics? -A-The entropy of the universe never decreases -B-A nonspontaneous process can occur if it is coupled to a process which is sufficiently spontaneous -C-The temperature of the universe stays the same...

PHYSICS-LAW OF THERMODYNAMICS
A dinner plate drops and breaks. This best illustrates the ______ law of THERMODYNAMICS A. 1st b. 2nd c. 3rd d. 4th I am inclined to say the 1st because energy can be neither created nor destroyed, it can only change forms. Thus the plate falling lost it's energy as a whole, ...

In the USA, it is customary to call the subject thermodynamics. Without the "s", the word "thermodynamic" is an adjective. It may be different in some English speaking countries. I do not recognize the meaning of "L" in KLPa. Do you mean KPa? (kiloPascals?) The air inside ...

Thermodynamics 2nd Law
The 2nd law of thermodynamics states that “in any spontaneous process, the total entropy of the universe always increases”. Yet in biological systems there are processes where there is a decrease in entropy during a reaction. Give an example of a biological process where ...

If I recall correctly, the British plural of ton is tonnes, and you are probably refering to metric tons (U.S. spelling), each with 1000 kg mass. It is not clear whether your 0.56 m/s is a speed or an acceleration rate. In the latter case, it should be written 0.56 m/s^2. This...
