• 0 °C

Question #11 (40 Points)• Explain why the melting and freezing

points are the same for a substance.

Answer #11 (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 #16 (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 #16 (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 #17 (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 #17 (20 points)

• C. Pot #1 and #2 would have the same melting points because they are filled with the same substance.

Question #18 (20 points)• A student is cooking

at home. She needs to melt 2 Tbs. of butter, and 2 Tbs. of peanut butter. If she heats both on high for the same amount of time, which would be true about their temperature changes?

A. Both substances would have the same temperature changes because they have the same volume.

B. Both substances would have different temperature changes because they are different substances.

C. None of the above answer are correct.

Answer #18 (20 points)

• B Both substances would have different temperature changes because they are different substances.

Question #19 (20 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 # 19 (20 points)• C, Pot #1 and Pot #2 would have the

same boiling point because each contains the same substance.

Question #20 (20 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 time it takes each pot to boil?

A. Pot #1 would boil faster because it has a lower volume.B. Pot #2 would boil faster because it has a higher volume.C. Pot #1 and Pot #2 would boil in the same amount of time because each contains the same substance.

Answer #20 (20 points)

• A. Pot #1 would boil faster because it has a lower volume.

Question #21 (20 points)A student is baking a cake at home. They need to dissolve flour, sugar, and cinnamon into milk.Which way would the student be able to dissolve it all the fastest?

A. Adding the flour, sugar, and cinnamon to ice cold water.B. Adding the flour, sugar, and cinnamon to room temperature water.C. Adding the flour, sugar, and cinnamon to hot water.D. None of the answers above are correct.

Answer #21 (20 points)• C. Adding the flour, sugar, and cinnamon to

hot water.
