Chapter 18, Problem 15TE

Two kids are sitting across from each other at a table trading their jellybeans. They both start out with the same number of jellybeans, but one of the kids is in a generous mood while the other is in a greedy mood. If each jellybean represents an electron, which kid ends up being slightly negative: the generous kid or the greedy kid? Who ends up being slightly positive? Is the generous kid just as negative as the greedy kid is positive? Would you describe this as a polar or nonpolar situation? What if both kids were equally greedy?

To determine

The kid ends up being slightly negative and the kid ends up being slightly positive. Whether the situation is polar or non polar. The suituation where both the kids are equally greedy.

Each jellybean represents an electron,two kids are sitting across from each other at a table trading their jellybeans. They both start out with the same number of jellybeans, but one of the kids is in a generous mood while the other is in a greedy mood.

Answer to Problem 15TE

The greedy kid will become slightly negative and the generous kid will become slightly positive. Since the generous kid will end up with less jellybeans and thus they are not just as negative as each other. The generous kid is a positive charge and the greedy kid is just as negative as the generous kid is positive thus this is a polar situation.If both kids were equally greedy then its nonpolar situation.

Explanation of Solution

The greedy kid and the generous kid both were selling the jellybeans and started with the same amount of jelly beans. Here in the given scenario, the jellybeans are acting as the electrons.

The generous kid will get good customers and thus will finish more amounts of jellybeans whereas the greedy kid will end up having more amount of jellybeans as it is. Thus, the greedy kid is having more jellybeans that mean more electrons thus gains negative charge while the generous kid is having less jellybeans that mean less electrons and thus gains a positive charge.

As the generous kid has sold more jellybeans than that of the greedy kid and thus the greedy kid will have an equal number of extra jellybeans than the generous kid.

The situation of the generous kid and the greedy kid thus depicts the polar nature. As in the polar condition, one atom has a slight negative charge while the other has a slight positive charge.

If both the kids will become equally greedy then the situation will become equal and thus then it will depict the nonpolar nature.

Conclusion:

Therefore, the greedy kid will become slightly negative and the generous kid will become slightly positive. Since the generous kid will end up with less jellybeans and thus they are not just as negative as each other. The generous kid is a positive charge and the greedy kid is just as negative as the generous kid is positive thus this is a polar situation.If both kids were equally greedy then its nonpolar situation.
