A dark blue beaker labeled 100 millimeters Y has an arrow leading to a pale blue beaker labeled 99 millimeters H subscript 2 O.

This has an arrow leading to a white beaker labeled 99 millimeters H subscript 2 O. Each arrow has a label 1 milliliter over it. The dark blue beaker has a box below it labeled Beaker number 1. The pale blue beaker has a box below it labeled Beaker number 2. The white beaker has a box below it labeled beaker number 3.
Does taking 1 mL of solution Y (pure bleach) out of the first beaker change the solution’s concentration?

What would the concentration of the second beaker be?

If Beaker #2 is a 1% solution of Y, and Beaker #3 is 1/100th of that in the final solution, what percentage solution would Beaker #3 be?

rjkz [21]

Answer:

0.116%

Explanation:

efficiency of sterling engine = 1 - ( 55 + 273 )k / ( 95 + 273 ) k

                                               = 1 - ( 328 / 368 ) = 0.10869

<u>Determine how efficient the transfer of energy via flame is </u>

apply this relation ; energy of steady state / energy output  ---- ( 1 )

where;  <em><u>energy output</u></em> = efficiency of sterling engine * energy

                                     = 0.10869 * 50 = 5.4345 J/sec

<em><u>energy of steady state</u></em> = 1/2 * I * w^2  ------ ( 2 )

I = moment of inertia of engine = 2 * 10^-5 kgm^2

back to equation 2 :  

energy of steady state = 1/2 * ( 2 * 10^-5 ) * ( 240 * 2π / 60 )^2

                                      = 630.88 * 10^-5  J /sec

Input values into equation 1

= [ (630.88 * 10^-5 )  / 5.4345  ] * 100

= 0.116%
