1. The 2nd Law of Thermodynamics states that the entropy of the universe ____ 2. Determine the ∆Gº using Appendix G for the following reaction. C2H5OH(l) + 3 O2(g) --> 2 CO2(g) + 3 H2O(l) Report your answer to four sig figs. Omit unit labels. Only add a - number is the sign is negative. Adding a + to a positive answer messes up the grading.
The second law of thermodynamics states that for any spontaneous process the entropy of the universe must increase. Explain how this statement (increasing entropy) relates to: lambda G_rxn lambda H_rxn lambda S_rxn For this process under standard conditions. H_2O_($) O longleftrightdoublearrow H_2O(f), circle the correct sign you predict for (a), (b), and (c) and explain your reasoning lambda G_rxn + or - lambda H_rxn + or- lambda H_rxn + or-(d) Explain how temperature affects the sign of lambda G in...
The first law of thermodynamics states that energy can neither be created nor destroyed. How then is it possible for ∆E to be anything other than zero? In other words, what do we mean when we call a physical scenario “non-conservative” if energy must, by nature, be conserved?
D Question 23 1 pts The Second law of Thermodynamics (Law of Entropy) states: e Perpetual motion is just that It takes energy to release energy Energy can neither be created nor destroyed Everything is moving from order to disorder Question 24 Order the following reproduction sequence: (Z)ygote (G)ametes (F)ertilization (M)eiosis (Go)nads o Go, M, G, FZ Go, G. M. F. Z o Z F. Go. M. G OM. Go. G. F. Z
Explain the answer Which statement can be attributed to the 2nd Law of Thermodynamics? For any real process, energy is conserved. For any real process, entropy is conserved. Energy flow has a direction. Energy has a magnitude.
The first law of thermodynamics teaches us the conservation of energy, which means the energy can be neither created nor destroyed. However, if you listen to the Public Radio, read Wall Street Journal or watch CNN, you can always learn that we are in the global shortage of energy. Is the First Law of Thermodynamics violated?
Question 9 Third Law of Thermodynamics states entropy is _when at zero kelvin and in a crystal (1 point) * infinite none one O zero Question 10 Second Law of Thermodynamics states entropy is ___always for the Universe (1 point) infinite O negative O positive O zero
Qualitative Predictions about Entropy
Another way of looking at entropy is that the universe is moving
toward a broader distribution of energy. The universe has a
constant amount of energy as stated in the first law of
thermodynamics. The universe started with low entropy (concentrated
in the moment before the "big bang") and the entropy has since been
constantly increasing by distributing this energy. Heat
distribution from high temperature to low temperature is a another
example of this phenomenon.
