- Consider the system shown in Figure 16.9. What is the change in entropy for the process where the energy is initially associated with particles A and B, and the energy is distributed between two particles in different boxes (one in A-B, the other in C-D)?arrow_forwardThe internal energy of a system is said to be the sum of the kinetic and potential energies of all the particles in the system. Section 10. 1 discusses potential energy and kinetic energy in terms of a ball on a hill. Explain potential energy and kinetic energy for a chemical reaction.arrow_forwardConsider an airplane trip from Chicago, Illinois, to Denver, Colorado. List some path-dependent functions and some state functions for the plane trip.arrow_forward
- A 5.33-g piece of Cu metal is heated to 99.7C in boiling water, then dropped into a calorimeter containing 99.53g of H2O at 22.6C. The calorimeter is sealed to the outside environment, and temperature equalizes. Cp[Cu(s)]=0.385J/gK, Cp[H2O]=4.18J/gK. a Discuss the process that occurs inside the calorimeter in terms of the zeroth and first laws of thermodynamics. b What is the final temperature inside the system? c What is the entropy change of the Cu(s)? dWhat is the entropy change of the H2O(l)? e What is the total entropy change in the system? f Discuss the process that occurs inside the calorimeter in terms of the second law thermodynamics. Do you expect it to be spontaneous?arrow_forward9.23 Which system does not work: (a) E=436J , q=400J ; or E=317J , q=347J ?arrow_forward9.29 In which case is heat added to the system: (a) E=43J , w=40J ; or (b) E=31J , w=34J ?arrow_forward
- Hesss law is really just another statement of the first law of thermodynamics. Explain.arrow_forward9.20 State the first law of thermodynamics briefly in your own words.arrow_forward9.72 Although it can be a nuisance when a laptop computer freezes up and needs to be rebooted, we accept that as somewhat inevitable. But clearly the need to occasionally reboot the control system for the power grid would not be acceptable. Use the web to research ways that engineers ensure the reliability of crucial systems like the control infrastructure of the grid, and write a paragraph summarizing the main strategies employed.arrow_forward
- Classify the following processes as exergonic or endergonic. Explain your answers. a.Any combustion process b.Perspiration evaporation from the skin c.Melted lead solidifying d.An explosive detonating e.An automobile being pushed up a slight hill from point of view of the automobilearrow_forwardWhich evolves more heat—freezing 100.0 g of benzene or 100.0 g of bromine?arrow_forwardExplain how the equation dU+pdVTdS0 is consistent with the idea that spontaneous changes occur with a decrease in energy and an increase in entropy.arrow_forward
