Suppose two blocks of iron, each having 1 mol of iron atoms, are at differing temperatures and are then brought together in an otherwise isolated system. One of the blocks is at 273.15 K and the other is at 373.15 K and the process is carried out at 1 bar pressure.

a.) Would you expect ∆Ssys < 0, ∆Ssys = 0, ∆Ssys > 0 ?

b.) Using common sense and high school physics (and perhaps the First Law), what is the common final temperature of the two blocks?

c.) Calculate ∆Ssys for the process (use Table 4.1 for any needed molar heat capacities needed, and assume that the molar heat capacities are independent of T).

d.) What is q for the isolated system? How does this value of q and the result of part C relate to the Clausius inequality: final initial d q S T − ∆ ≥ ∫ ?

e.) Interpret this change in entropy in terms of the ordering-disordering effects involved in the transfer of given amount of heat from a block at higher temperature to one at a lower temperature (i.e. the disordering effect of adding a given q to the cooler block vs the ordering effect of removing the same q from the hotter block).

Molar heat capacity of Fe(s) ==> Cp,m (J / mol*K) = 25.1

Report from previous shift:

Mr. Robert Josh is a 55-year-old native american male who was admitted to our unit at 0700 this morning after being admitted to the ED at 0200 with a diagnosis of dehydration and hypokalemia. Nurse are monitoring his fluid and electrolyte status closely. Nurse have just received admission orders. Two days ago, he developed abdominal cramping, nausea, vomiting, and severe diarrhea 10 hours after eating lunch at a local restaurant. The symptoms have continued for the past 2 days, and food and fluid intake has been minimal to none since the symptoms began. Last night he nearly passed out while going to the bathroom around 0400. Mr. Josh was brought to the ED by his son, and reported dizziness, weakness, and continued nausea. He received 4 mg zofran IV for nausea in the ED. Lab work was drawn and is available in the patient chart, and urine and stool samples have been sent to the lab. Mr. Josh is drowsy but oriented x 3, appears ill, and is irritable. He reports having a headache, which he rates a 3 on a scale of 0–10, but he hasn't wanted anything for it. Admission weight was 72 kg (161 lb), which the patient reports to be about 4.5 kg (10 lb) less than usual. Vital signs were obtained on admission, including orthostatic blood pressure readings. Heart rate is tachycardic and irregular. He has only taken a few ice chips since admission due to his nausea. The patient had one small liquid stool in the ER. He has not voided or experienced emesis since admission. An IV bolus has been completed and now normal saline is running at 155 mL/hr. Mr. Josh has new IV orders that need to be initiated. Nurse will need to start him on oral antibiotics and potassium when nausea resolves. Provide patient education on safety, his prescribed medications, and intake and output measurement

Fabulous is a retail company that sells specialized gardening products. The company is considering opening a new store on October 1, Year1. As budget coordinator, you have been asked to prepare a master budget for the first 3 months of the company’s operation. You have gathered the following information:

October sales are estimated to be $500000 of which 45 percent will be cash and the remainder will be on credit. The company expects all sales to increase at the rate of 10 percent per month for November and December. Sales in January Year 2 are expected to be $400000.

The company expects to collect 100 percent of the accounts receivable generated by credit sales in the month following the sale.

Prepare a sales budget and a schedule of cash receipts using these facts and your excel template. Check your answers here before moving to the next part, by completing the cells requested in the chart below.

The cost of goods sold is 80 percent of sales. The company desires to maintain a minimum ending inventory equal to 30 percent of the next month’s cost of goods sold. (Ending inventory for December is based on budgeted January Year2 sales.)

Assume that all inventory purchases are made on account (on credit). The company pays 40 percent of accounts payable in the month of purchase and the remaining amount in the following month.

In excel, prepare an inventory purchases budget and a cash payments budget for inventory purchases. Use the check figures below before you continue.

Budgeted selling and administrative expenses per month follow.

• Salary expense (fixed): $ 38400
• Sales commissions:  5 percent of Sales
• Supplies expense:   2 percent of Sales
• Utilities (fixed): $3200              
• Depreciation on store equipment (fixed)*:   You compute    
• Rent (fixed) $ 12000          
• Miscellaneous (fixed): $ 2000      

*The capital expenditures budget indicates that the company will spend $900000 on October 1 for store fixtures, which are expected to have a $24000 residual value and a 96 month useful life.

Utilities and sales commissions are paid the month after they are incurred; all other expenses are paid in the month in which they are incurred.

In excel, prepare the selling and administrative expenses budget and the cash payments budget for selling and administrative expenses. Check the key figures below.

Fabulous issued common stock for $600000 on October 5.

A dividend of $2600 was paid on December 15.

The company borrows and repays funds in increments of $1,000 on the last day of the month. The company also pays its vendors on the last day of the month. It pays interest of 1percent per month in cash on the last day of the month. To be prudent, the company desires to maintain a $40000 cash cushion.   

Prepare a cash budget on your excel template. Check key figure below.
