Air, initially at 220 kPa and 450 K undergoes a polytropic state change to 374 kPa and 495 K. What is the polytropic exponent of this process? and Saturated water vapor is contained in a rigid container. Heat is then added until the the pressure and temperature become 861.818 MPa and 400 ?C, respectively. What was the initial temperature of the steam? ?C Solution PV n =C PV=nRT V= nRT/P P( nRT/P) n =C P 1 (T 1 /P 1 ) n =P 2 (T 2 /P 2 ) n (T 1 P 2 /T 2 P 1 ) n =P 2 /P 1 n= ln(P 2 /P 1 )/ln(T 1 P 2 /T 2 P 1 )= 1.218944 .

According to the most recent Labor Department data- 10-5- of engineers.docx
According to the most recent Labor Department data, 10.5% of engineers (electrical, mechanical, civil, and industrial) were women. Suppose a random sample of 50 engineers is selected. How likely is it that the random sample of 50 engineers will contain 8 or more women in these positions?

0.0821
Solution
random sample = 50
% of engineers (electrical, mechanical, civil, and industrial) who were women p = 10.5
Sample proportion phat >= 8/50
phat >= 0.16
Std error = sqrt[p * (1 - p)/n] = sqrt[0.105 * (1 - 0.105)/50] = 0.043
probability that the random sample of 50 engineers will contain 8 or more women in these positions is given by 1 - P[Z = (phat - p)/std error]
= 1 - P[Z = (0.16 - 0.105)/0.043]
= 1 - P[Z = 1.27]
= 1 - 0.898 = 0.1020

Abstraction is an important quality of an Operating System- Explain ho.docx
Abstraction is an important quality of an Operating System. Explain how Operating Systems and abstraction are related.
Solution
Abstraction is the concept of hiding the low level details and showing the high level details and allowing the methods within the class to access the members or member variables.
Coming to operating systems everything is abstract and should be abstract. If the operating system allows the applications to access the low level details, there is a high risk of the operating system being manipulated. And ofcourse the other risk is that, it will be tough for the novice to access the operating system to access the machine, when they don\'t have some basic knowledge.
Therefore the abstraction of an operating system is an important quality by all means.

Absorbance measurements were taken on a series of Fe standards complex.docx
Absorbance measurements were taken on a series of Fe standards complexed with 1,10-phenanthroline. A plot of absorbance vs. concentration yielded a linear curve with the equation y = 1008x + 0.0395 (where y is the absorbance and x represents the fe con entaton in mol-L). Using his informatio calcula e he i concentration (in ppm) in a 30.0-mL aliquot of ground water that produced an absorbance of 0.608
Solution
equation :
y = 1008 x + 0.0395
y = absorbance = 0.608
x =concentration
y = 1008 x + 0.0395
0.608 = 1008 x + 0.0395
x = 5.64 x 10^-4
concentration = 5.64 x 10^-4 mol / L
= 0.0315 g / L
= 31.5 mg / L

a-What is the cause for the difference between thermosetting and therm.docx
Thermoplastics can be re-melted and recycled fairly easily as they usually contain additives that change material properties. Thermosets are cured and molded into shape through molecular changes caused by catalysts, making them difficult to recycle compared to thermoplastics. The key difference is that thermoplastics can be reshaped while thermosets maintain their molded form.

Abacus Co- wishes to maintain a growth rate of 12-4 percent a year- a.docx
Abacus Co. wishes to maintain a growth rate of 12.4 percent a year, a debt–equity ratio of 1.2, and a dividend payout ratio of 28 percent. The ratio of total assets to sales is constant at 0.92. What profit margin must the firm achieve?
Solution
Equity multiplier = (1+ debt equity ratio)
= 1+1.20
= 2.20
ROE = profit margin x turnover x Equity multiplier
= profit margin x 1/0.92Â Â x 2.20
Growth rate = ROE x (1- payout ratio)
0.124 = profit margin x 1/0.92Â Â x 2.20 x (1-0.28)
Proit margin = 0.124 x 0.92 / (2.2 x 0.72)

Solution
a) Bromine and iodine are chemically similar. Both comes in group 7A and have almost similar properties. Eventhough fluorine also is in group 7A, it is different from the other two because of its small size and high electronagativity.
b) Oxygen and sulphur. They belong to group 6A of the periodic table. They both have six valence electrons.
c) Lithium and potassium. They belong to group 1 and contains one valence electron.

D) A nimals are multicellular, heterotrophic eukaryotes that obtain nutrients by ingestion.
Solution
Option (C) is incorrect.
Animal cells DO lack cell walls, but they have cell membranes.
However, option (B) is also incorrect because most animals are diploid and reproduce with meiosis and mitosis. BUT Animal gametes are haploid and reproduce by mitosis (after being produced through meiosis).

- 1. Air, initially at 220 kPa and 450 K undergoes a polytropic state change to 374 kPa and 495 K. What is the polytropic exponent of this process? and Saturated water vapor is contained in a rigid container. Heat is then added until the the pressure and temperature become 861.818 MPa and 400 ?C, respectively. What was the initial temperature of the steam? ?C Solution PV n =C PV=nRT V= nRT/P P( nRT/P) n =C P 1 (T 1 /P 1 ) n =P 2 (T 2 /P 2 ) n (T 1 P 2 /T 2 P 1 ) n =P 2 /P 1 n= ln(P 2 /P 1 )/ln(T 1 P 2 /T 2 P 1 )= 1.218944
