Question 8: A gas sample is compressed from a larger volume to a smaller volume. Which of the following is true? A change in volume has no effect on number of microstates or entropy. The number of microstates available to the system is decreased and the system's entropy is decreased The number of microstates available to the system is increased and the system's entropy is decreased The number of microstates available to the system is decreased and the system's entropy is increased The number of microstates available to the system is increased and the system's entropy is increased Chock

Classify the following processes as exergonic or endergonic. Explain your answers. a.An automobile being pushed up a slight hill from point of view of the pushing b.Ice melting from point of view of the ice c.Ice melting from point of view of surrounding of the ice d.Steam condensing to liquid water from point of view of the steam e.Steam condensing to liquid water from point of view of surrounding of the steam

The 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.

xplain why aluminum cans make good storage containers for soft drinks. Styrofoam cups can be used to keep coffee hot and cola cold. How can this be?

Would the amount of heat absorbed by the dissolution in Example 5.6 appear greater, lesser, or remain the same if the experimenter used a calorimeter that was a poorer insulator than a coffee cup calorimeter? Explain your answer.

9.68 What are some features of petroleum that make it such an attractive fuel?

For each process, tell whether the entropy change of the system is positive or negative. Water vapor (the system) deposits as ice crystals on a cold windowpane. A can of carbonated beverage loses its fizz. (Consider the beverage but not the can as the system. What happens to the entropy of the dissolved gas?) A glassblower heats glass (the system) to its softening temperature.

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)?

Describe the energy and entropy changes that occur in the following processes, and indicate whether the processes are spontaneous under the conditions stated: a.Lumber becomes a house b.A seed grows into a tree. c.On a hot day, water evaporates from a lake.

Explain in your own words what is meant by the term entropy. Explain how both matter spread and energy spread are related to the concept of entropy.
