Answer:

D) All of the above are correct

Explanation:

In general terms, luxurious, or non-necessary items that have many substitutes are more elastic than daily necessities such as food or gasoline.

Flat-screen computer monitors are a luxury item, and a regular-screen monitor works just as well, therefore, if the price of them rises a lot, people can always buy regular monitors. The demand for this product is very elastic.

Same is true for grandfather clocks, which not only are expensive, but also niche, in the sense that they likely only appeal to a small segment of people.

As for cardboards, this product also has substitutes, and the demand for it in the long-term is more elastic because people will have more time to look for those substitutes.

Estimate the liquid density (g/cm3) of propane at 298 K and 10 bar. Compare the price per kilogram of propane to the price of re

Deffense [45]

Answer:

Density of propane = 17.8 g/L

Propane is more priced than gasoline

Explanation:

Given:

Temperature, T = 298 K

Pressure, P = 10 bar = 0.987 × 10 = 9.87 atm

now,

Molar mass of propane, M = 44.1 g/mol

From ideal gas law

⇒ PV = nRT

here,

n is the number of moles

R is the ideal gas constant = 0.0821 L.atm/mol.K

also,

Density, D = $\frac{\textup{Mass}}{\textup{Volume(V)}}$

V = $\frac{\textup{Mass}}{\textup{D}}$

and,

nM = mass

thus,

V = $\frac{\textup{nM}}{\textup{D}}$

substituting in the ideal gas relation

we have

P = $\frac{\textup{DRT}}{\textup{M}}$

D = $\frac{\textup{PM}}{\textup{RT}}$

D = $\frac{9.87\times44.1}{0.0821\times298}$

D = 17.8 g/L

Now,

1 gallon = 3.78 Liter

Therefore,

5 gallon = 5 × 3.78 Liter = 18.9 Liter

Thus,

mass of 5 gallon propane = Volume × Density

= 18.9 Liter × 17.8 g/L

= 336.42 g

= 0.336 kg

also it is given that Price of 5 gallon propane i.e 0.336 kg = $30

Therefore,

Price per kg = $\frac{30}{0.336}$

= $89.28

and,

Mass of 5 gallons i.e 18.9 Liter gasoline = Density × Volume

= 0.692 g/cm³ × 18.9 Liter

also,

1 L = 1000 cm³

thus,

= 0.692 g/cm³ × 18.9 × 1000 cm³

= 13078.8 g

= 13.078 kg

Therefore,

Price per kg of gasoline = $\frac{\$30}{13.078}$

= $2.29

hence, propane is more priced than gasoline
