Which of the following changes to a pipe would increase the conductance by a factor of 12?
ivanzaharov [21]

C. Tripling the length and reducing the radius by a factor of 2 is the change to a pipe would increase the conductance by a factor of 12.

<u>Explanation:</u>

As we know that the resistance is directly proportional to the length of the pipe and it is inversely proportional to the cross sectional area of the pipe.

So it is represented as,

R∝ l /A [ area is radius square]

So k is the proportionality constant used.

R = kl/A

Conductance is the inverse of resistance, so it is given as,

C= 1/R.

R₁ = kl₁ / A₁

R₂ = kl₂/A₂

R₂/R₁ = 1/12 [∵ conductance is the inverse of resistance]

        = l₂A₁ / l₁A₂

If we chose l₁/l₂= 3 and A₂/A₁= 4 So R₂/R₁= 1/3×4 = 1/12

So tripling the length and reducing the radius by a factor of 2 would increase the conductance by a factor of 12.

Consider these ground-state ionization energies of oneelectron species:
SVETLANKA909090 [29]

Answer:

Explanation:

general expression for the ionization energy of any one-electron species.

=  z² x ground level energy / n²

z is atomic no , n is energy level .

ground level energy of

 H = 1.31 x 10³ kJ/mol

He⁺ = 2² x  1.31 x 10³ kJ/mol  =  5.24 x 10³ kJ/mol

Li²⁺ = 3² x  1.31 x 10³ kJ/mol   = 1.18 x 10⁴ kJ/mol

b ) the ionization energy of B⁴⁺.

= 5² x 1.31 x 10³ kJ/mol  = 32.75 x 10³ kJ/mol  

c )  minimum energy required to remove the electron from the n = 3 level of He⁺ per mole

= 5.24 x 10³ / 9  kJ/mol

= 5.82 x 10² kJ/mol

= 5.82 x 10² x 10³ / 6.02 x 10²³ J

.9667 X 10⁻¹⁸ J

= .9667 X 10⁻¹⁸ / 1.6 X 10⁻¹⁹ eV

= 6.042 eV

= 1237.5 / 6.042

= 204.82 nm

What is density? what does it tell you about substance?
Alekssandra [29.7K]

Hello!

Explanation:

↓↓↓↓↓↓↓

Density is the amount of mass in a given volume. It's a derived unit of measure. It is equal to mass divided by volume. It's measured in units such as grams per cubic centimeter and grams per milliliter. Density is the ratio of mass to volume. Density is a physical property of an object. It is degree of compactness of a substances. Relative density is used to separate solids, liquids, and gases. The gas in the container rises to the top because it has the least density. The liquids separate into individual layers based on their relative densities. The least dense liquid is on top. The most dense liquid is on bottom. The solids sink to the bottom of the container because they have the greatest density.

Hope this helps!
