3.- ENTROPY EXERCISES.
From the absolute entropy values calculate the standard entropy changes (ΔS °) of the following reactions at 25 C

a.-                               CaCO_3(s) →→→ CaO _(s)     + CO_2(g)

b.-                               N_2(g)   +      3H_2(g)      →→→    2NH_3(g)

c.-                               H_2(g)     +     Cl_2(g)   →→→   2HCl _(g)

TABLE OF VALUES OF STANDARD ENTROPY (S °):

1-Demonstrate how the spectral emissive power inside a blackbody cavity changes with respect to the
following parameters:
a) Temperature and wavelength, hence, find E?(?, T), by:
(i) Creating a table with the (?, T) values as follows:
1. Wavelengths, ?, from 0.1 ?m to 100 ?m, on the first (left-most) column. Use increments
of:
? 0.1 ?m from 0.1 ?m to 1.0 ?m;
? 0.5 ?m from 1.0 ?m to 10 ?m;
? 1.0 ?m from 10 ?m to 100 ?m;
2. Temperatures, T, values of: 273.15 K; 773.15 K; 1273.15 K; 1773.15 K; 2273.15 K; 5000
K; and, 10000 K.
3. Calculate E?(?, T) using units of W/m2·?m and assume the constants C1 = 374210000
and C2 = 14388.
Set up your table with each separate column corresponding to each given value of T.
Ensure that you clearly label each column in your table and include the relevant units.
[Hint: There should be seven separate columns in your table for the E?(?, T) calculations
and eight columns in your table altogether with the inclusion of the left-most column
consisting of the ? values.
The recommendation is that you fill in each separate column in your table using a
different background colour in order to facilitate the examination of the different T
calculations and to assist in identifying the corresponding plots.]
4. Clearly demarcate the visible region in your table. You may do this by selecting a
different coloured font for the values of ? (and the corresponding E? values) that fall
within this region.
(ii) Plot the calculated values of E?(?, T) ensuring that you set out each plot as follows:
1. Display the calculated E?(?, T) values on the vertical axis.
2. Display the wavelengths on the horizontal axis. Select the logarithmic scale, to base 10,
to display your values on this axis.
3. Clearly demarcate the visible region in each plot.
4. Include a title in each plot, clearly identifying the relevant value of T and ensure that you
label both axes (including units).
[Hint: The recommendation is that you fill in the background of each plot in the same
colour as the corresponding column in your table in order to facilitate the analyses of
the different T calculations.]

1. The following problem has you examine the impact of interest rate changes on bank profits using basic gap analysis.

   Assume that the amount of variable- and fixed-rate assets and liabilities is fixed over the next year. In other words, no assets or liabilities will mature during this period. For each part, be sure to give a numerical answer.

   1. Suppose a bank has $70M in variable-rate assets and $120M in variable-rate liabilities. What is the impact on the bank’s profits of a 1.5% increase in interest rates?

   2. If the bank has $200M in assets, what is the impact on the return on assets (ROA)?

   3. If the bank has $200M in assets and an capital of $15M, what is the impact on the

      return on equity (ROE)?

Use the dynamic AD-AS model to explain circumstances by which productivity and technological changes can lead to an increase in unemployment. Discuss what happens to the price level depending on the assumptions you make.(please explain in detail)

1. what are the common age-related changes of respiratory system in older adult?
2. In selected respiratory conditions: Give nursing management and medication.
a. Chronic Obstructive Pulmonary Disease
b. Lung cancer
c. Pneumonia
3. What self-imposed and environmentally imposed risks to younger adults can contribute to the development of respiratory conditions in later life?

A parcel of air moves adiabatically and without phase changes of water from 900 hPa (Point A) to 700 hPa (Point B) and then to 800 hPa (Point C).

(a) At which of these three points is the relative humidity the largest, and at which point is it the smallest? Justify your answer

(b) At which of these three points is the specific humidity the largest, and at which point is it the smallest? Justify your answer

Calculate the heat/mole KCl when KCl is dissolved in water if 3.00 grams of KCl changes the temperature of 301 mL of water from 23^oC to 29^oC. (s_water = 4.184 J/g^oC)

What material changes could advance the item leading?

(for example, to improvements in sustainability, accessibility, affordability, equity, performance, etc..)

Use materials property data and knowledge of materials selection strategies to support your proposed material innovation.
