Five moles of monatomic ideal gas are contained at a pressure of 4 atm and a temperature of 250 K. 35400 J of heat are transferred to the gas. Then, the gas pressure is used to expand a piston, and the expanding gas does 1200 J of work against its surroundings. However, the piston is not perfectly insulated, and 600 J of heat is lost from the gas during the expansion. All processes are reversible. Calculate the final temperature of the gas.

You are given the partial implementation of class IntegerLinkedList which stores integers in the inked list. Add a public member function that does the following:
// Complete this for Problem 2
int getSmallestIndex(): return the smallest of integers stored in the linked list.
A main file (prob2.cpp) is provided:
#include <iostream>
#include <string>
#include "IntegerLinkedList.h"
using std::string;
using std::cout;
using std::endl;
int main() {
{
IntegerLinkedList mylist;
mylist.addFront(10);
mylist.addFront(17);
mylist.addFront(23);
mylist.addFront(17);
mylist.addFront(92);
if (mylist.getIndexSmallest() == 4)
cout << "PASSED" << endl;
else
cout << "Result did not match expected answer: 4" << endl;
}
{
IntegerLinkedList mylist;
mylist.addFront(10);
mylist.addFront(17);
mylist.addFront(23);
mylist.addFront(37);
mylist.addFront(2);
if (mylist.getIndexSmallest() == 0)

bool isLesser (SNode *ptr, int compare) {
return false; // COMPLETE THIS FOR PROBLEM 3
}
public:
IntegerLinkedList() {

}
void addFront(int x) {
SNode *tmp = head;
head = new SNode;
head->next = tmp;
head->data = x;
}
int getIndexSmallest(); // COMPLETE THIS FOR PROBLEM 2
// recursion helper function called from main
bool isLesserHelper (int compare) {
return isLesser(head, compare);
}
};
Add a recursive function called isLesser to class IntegerLinkedList to calculate the smallest of the linked list’s data values (same as in Problem 2 but recursive).
A recursion “helper” function is already included in class IntegerLinkedList. You only need to write the recursive function.
//PROBLEM 3

#include <string>
#include "IntegerLinkedList.h"

Dobrinski Corporation has provided the following information concerning a capital budgeting project:
| After-tax discount rate | 14 | % | |
| Tax rate | 30 | % | |
| Expected life of the project | 4 | ||
| Investment required in equipment | $ | 274,000 | |
| Salvage value of equipment | $ | 0 | |
| Working capital requirement | $ | 38,500 | |
| Annual sales | $ | 715,000 | |
| Annual cash operating expenses | $ | 531,000 | |
| One-time renovation expense in year 3 | $ | 72,750 | |
The company uses straight-line depreciation on all equipment. Assume cash flows occur at the end of the year except for the initial investments. The company takes income taxes into account in its capital budgeting.
Click here to view Exhibit 13B-1 to determine the appropriate discount factor(s) using table.

The Chocolate Ice Cream Company and the Vanilla Ice Cream Company have agreed to merge and form Fudge Swirl Consolidated. Both companies are exactly alike except that they are located in different towns. The end-of-period value of each firm is determined by the weather, as shown below. There will be no synergy to the merger.
| State | Probability | Value | ||||
| Rainy | .1 | $ | 400,000 | |||
| Warm | .4 | 580,000 | ||||
| Hot | .5 | 1,100,000 | ||||

the other. Furthermore, each company has an outstanding debt claim
of $580,000. Assume that no premiums are paid in the merger.

Students performed a procedure similar to Part III of this experiment (Analyzing a Vitamin Supplement for Vitamin C Content) as described in the procedure section. A 1.043g vitamin C tablet is crushed, treated, and diluted to 100.00mL in a volumetric flask with deionized water. Three 5.00mL samples of this solution are titrated with DCP that had a standardized concentration of 9.93x10-4M. The three titrations took an average of 35.52mL of DCP. (MM Ascorbic Acid = 176.124 g/mol)
Calculate the mass (in mg) in the vitamin C tablet. (MM Ascorbic Acid = 176.124 g/mol)
