Question #5 (40 Points)Explain why the melting and freezing
points are the same for a substance.
Answer #5 (40 points)Anything above this temperature point
the substance melts, but anything below it begins to freeze. This is why the melting and freezing points are the same.

Question #6 (10 points)
0 °C
Question #7 (10 points)
What is the boiling point of water in °C?
Answer #7 (10 points)
100 °C
Question #8 (10 points)What is the freezing point of water in
°C?
Answer #8 (10 points)
0 °C
Question #9 (20 points)• A student is attempting
to melt an iron nail for a home experiment. The student puts 1 nail in Pot #1 and 3 nails in Pot #2. The student heats both pots on high for the same amount of time. Which would be true about its temperature changes?
A. Pot #1 will have a greater change in temperature because there is less volume.
B. Pot #2 will have a greater change in temperature because there is more volume.
C. Pot #1 and #2 will have the same change in temperature because they are melting the same substance.
D. Pot #1 will have a smaller change in temperature because there is less volume.
Answer #9 (20 points)
A, Pot #1 will have a greater change in temperature because there is less volume. There is only 1 nail in there instead of 3.
Question #10 (20 points)In the same situation as the previous question, which would be true about the melting points of the iron nails?
A. Pot #2 would have a higher melting point because it is filled with more mass.
B. Pot #1 would have a higher melting point because it is filled with less mass.
C. Pot #1 and #2 would have the same melting points because they are filled with the same substance.
D. None of the above answers are correct.
Answer #10 (20 points)
C. Pot #1 and #2 would have the same melting points because they are filled with the same substance.
Question #11 (30 points)• A student is boiling
milk at home to make hot chocolate for herself and her friends. In Pot #1 she adds 1 L of milk. In Pot #2 she adds 10 L of milk. Which would be true about the boiling point of each pot?
A. Pot #1 would have a lower boiling point because it has a lower volume.
B. Pot #2 would have a lower boiling point because it has a higher volume.
C. Pot #1 and Pot #2 would have the same boiling point because each contains the same substance.
Answer # 11 (30 points)C, Pot #1 and Pot #2 would have the
same boiling point because each contains the same substance.
Question #12 (30 points)A camper roasts marshmallows in a

A. molecule B. atomC. protonD. element
Answer #15 (30 points)• Two oxygen atoms bond with one
carbon atom to form carbon dioxide. Carbon dioxide is a(n)
A. molecule
Question #16 (20 points)• The atoms and molecules in your pencilA. move only when the pencil is being usedB. vibrate back and forth in place C. don't move at all D. slide from place to place through the
pencil
Answer #16 (20 points)• The atoms and molecules in your
pencilB. vibrate back and forth in place
