Enthalpy is defined as the measure of energy in a thermodynamic system. The value of enthalpy is considered to be equal to the internal energy of the system and the product of pressure and volume. Calorimeter is usually used to obtain the value of enthalpy of a system. 
A coffee cup calorimeter is an effective way of measuring the enthalpy of a system because it is a constant pressure calorimeter. This means that, the heat that is measured in a coffee cup calorimeter is equivalent to the change in enthalpy; also its use result in little or no volume change to the system involved.

tatyana61 [14]

Given:

Total cash = $160,000

Notes payable = $86,000

Common stock = $52,800

Find:

Retained earnings as on December 31, 2018

Computation for retained earning:

According to Accounting Equation:

Assets = Liabilities + Stock holder equity

Total Cash = Notes payable + Common stock + Retained earning

$160,000 = $86,000 + $52,800 + Retained earning

$160,000 = $138,800 + Retained earning

Retained earning = $160,000 - $138,800

Retained earning = $21,200

Ivan

Answer:

a. $842,250

b. $842,250

Explanation:

The computation is shown below:

a. For avoidable interest

<u>Weighted average               Interest rate applied  avoidable interest</u>

<u>accumulated expenditures </u>

$5,205,000                               10%                           $520,500

$2,925,000                                11%                            $321,750

Total                                                                             $842,250

($8,130,000 - $5,205,000)

Working note for interest rate applied

<u>Particulars                   Principal                Interest</u>

12% ten year bond    $6,047,000            $725,640    

9% 3 year bond         $3,023,500            $272,115

total                            $9,070,500            $997,755

Now the interest rate is

= $997,755 ÷ $9,070,500

= 11%

2. Now the total interest capitalized is

Total interest is

= $520,500 + $725,640 + $272,115

= $1,518,255

And, the total avoidable interest is $842,250

So we considered the lesser amount i.e. $842,250
