Question

Explain to me in breif and simple way/ fick's first and second
laws

Answer #1

Solute will move from higher concentration to lower concentration when the barrier from two compartment is removed. The amount of solute moves from higher concentration to lower concentration per unit area per unit time due to concentration gradient is called diffusion flux.

First law deals for steady state diffusion, where diffusion flux is independent of time

Second law is deployed when concentration gradients varies with time, I.e for diffusion flux is dependent upon time. I.e for non steady diffusion flux

Define First and Second Laws of Thermodynamics, and explain the
first law devices and second law devices based on Laws of
Thermodynamics. For analyzing power cycles, summarize the
idealizations and simplifications employed in the analysis of power
cycles. Explain Carnot Cycle using a pressure-volume (P-v) diagram
with each process.

Can someone please explain the edgeworth box in a simple way to
me?

State Newton's First and Second Laws (qualitative
explanations).

State the first two laws of Thermodynamics and give a
mathematical representation. (Explain the meaning of the
symbols)

Explain the role of the laws of thermodynamics in
various engineering processes as regards feasibility. in the
explanation write about the first and second law in terms of their
application mentioned above; indicate their limitations.

Kepler's laws describe the motions of the planets; however they
do not explain why planets move this way. Pick one of Kepler's laws
and use Newton's laws of motion to explain it.

Can
anyone explain to me in simple terms diasteromeric ratios and NMR I
am so lost.

how
Newton derivate his laws from Kepler?
second laws of motion?
Law of Gravitation?

Can anyone explain in simple words this questions. I read the
text and it's confusing me even more.
Explain why the Factory Overhead Balance must be disposed of at
year end?
Thank you

Explain the difference between the first and second welfare
theorems.
A.
The first welfare theorem discusses a competitive equilibrium
with the help of the government; the second welfare theorem
discusses a competitive equilibrium without the help of the
government.
B.
The first welfare theorem states that a competitive equilibrium
is Pareto-optimal under certain conditions; the second welfare
theorem states that a Pareto optimum is a competitive equilibrium
under certain conditions.
Your answer is correct.
C.
The first welfare theorem discusses...
