The reason for the scenario is because the cocoa was mixed with hot water but some cocoa settled as it cooled because the solubility went down.

  • Solubility simply means the amount of a substance that can be used in dissolving an amount of solvent at a particular time.

  • In this scenario given, it should be noted that the brown solids in the bottom of the mug were due to the fact that the solubility went down when the cocoa was mixed with water.

In conclusion, from the complete question, the correct option is C.

Follow the directions to convert the analog sound wave into a digital signal. the lines on the grid intersect at various points
dmitriy555 [2]

In this exercise we have to observe the axes of the graph to associate the values ​​of X with those of Y that correspond to 0, 5, 5, -3, -5, -3, 2, 0, 0, -1, -2, 1, 1, -1, -1, -2, 2, 3, -1.

<h3>How to calculate the Cartesian plane?</h3>

Just draw two lines: one of them vertical, starting from the point until it finds the x axis; another horizontal, starting from the point until it meets the y-axis.

Then plotting the value of X on the graph we find the following for each value of X to Y:

  • X= 0 ; Y= 0;
  • X= 1 ; Y= 5;
  • X= 2 ; Y= 5;
  • X= 3 ; Y= -3;
  • X= 4 ; Y= -5;
  • X= 5 ; Y= -3;
  • X= 6 ; Y= 2;
  • X= 7 ; Y= 0;
  • X= 8 ; Y= 0;
  • X= 9 ; Y= -1;
  • X= 10 ; Y= -2;
  • X= 11 ; Y= 1;
  • X= 12 ; Y= 1;
  • X= 13 ; Y= -1;
  • X= 14 ; Y= -1;
  • X= 15 ; Y= -2;
  • X= 16 ; Y= 2;
  • X= 17 ; Y= 3;
  • X= 18 ; Y= -1;
