2nd law of thermodynamics. (a) Explain the second law of
thermodynamics and use an example to illustrate why this law is
true. (b) Given the 2nd law of thermodynamics, how is it
thermodynamically possible that a protein can spontaneously fold
given the inordinate number of conformations available to it in the
denatured form and the limited allowable arrangements in the native
form (i.e., ΔS < 0 for the protein folding process).
a statement of the first law of thermodynamics is that a. in a
spontaneous process, the entropy of the universe increases b. there
is no disorder in a perfect crystal at 0 k. c. the total energy of
the universe is constant. d. the totla energy of the universe is
constant. e. mass and energy are conserved in all chemical
reactions
Determine which of the following sets of data satisfy the first
law of thermodynamics? (Recall that E = total energy = U + KE +
PE)
a. W = 50 kJ Q = 170 kJ DeltaE = 120 kJ
b. W = 100 Btu Q = -110 Btu DeltaE = -210 Btu
c. W = 250 kJ Q = -110 kJ DeltaE = -100 Wh
d. W = 44 kPa-m3 Q = -84 kPa-m3 DelatE = 40 kN-m
The project is to "Design and build an experiment to verify the
first law of thermodynamics by stirring air with an electric motor
powered paddle, in a well-insulated container." We are planning on
finding the work of the motor and seeing if it equal to the change
in internal energy of the container. The only problem is that we
are confused on how to find the internal energy. What would be the
best/easiest way to solve this? Also since the...
There is an experiment that demonstrates the first law of
thermodynamics by using a tin can. The problem is I don't
understand why there is a work done. The link to that video is
https://youtu.be/jNPUCmkKiE4?list=WL&t=180 . Can someone
explain to me why the tin can suddenly imploded?
