Please help! Can someone give me answers for 2.08 Graded Assignment: Boiling and Melting Points Exploration for 8th grade science Here are the questions
(I couldn't make the graph)

1. Looking at the line plots on your graph, describe how boiling point and melting point vary with respect to atomic number.

2. Now look at the segment of the graph between the two data points marked with black squares. Describe how the boiling point and melting point plots behave between these points. Be as specific as possible.

3. On your graph, the data points between the black squares are data for elements with atomic numbers 3 through 9. Locate these elements on your periodic table. What term or description would you use to identify these elements with respect to the periodic table?

4. Now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. For each of these lines, describe any trends you see.

5. Locate the elements on your periodic table that you circled in green on your graph. What term or description would you use to identify these elements with respect to the periodic table?

6. After reviewing your answers to questions 2 and 4 above, would you define boiling point and melting point as a periodic table family trend (vertical groups), period trend (horizontal rows), or neither? Explain your answer.

7. Using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. Explain your answers.

1.Looking at the line plots on your graph, describe how boiling point and melting point vary with respect to atomic number.

      As the atomic number increases, the boiling point increases due to there being more electrons, which creates a larger strength of negative charge around the nucleus of the atom.  

2.Now look at the segment of the graph between the two data points marked with black squares. Describe how the boiling point and melting point plots behave between these points. Be as specific as possible.

The graph shows relation between the melting point and the boiling point

3.On your graph, the data points between the black squares are data for elements with atomic numbers 3 through 9. Locate these elements on your periodic table. What term or description would you use to identify these elements with respect to the periodic table?

All of these elements can be found in the second period of the periodic table.

6.After reviewing your answers to questions 2 and 4 above, would you define boiling point and melting point as a periodic table family trend (vertical groups), period trend (horizontal rows), or neither? Explain your answer.

     Neither, boiling and melting point per element varies from element to element on the periodic table. Family trends and period trends determine what kind of element each aspect is.  

7.Using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. Explain your answers.

Gas would be room temperature because it fills up its container and helps the temperature of the room.

Explanation:

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
