Sometimes matter behaves in unexpected ways. For example, some people claim that hot water will freeze into ice cubes faster than cold water. Could this be true? Describe an experiment that you could perform to test this question. Be sure to include the materials, procedure, and data you would collect.

Answers

Answer 1
Yes this could be true.

Materials:
-Freezer
-3 bowls of equal size and shape
-Sticky labels
-Marker
-Water
-Measuring cup
-Thermometer
-Notebook
-Pencil

Procedure:
1. Clear enough room in your freezer for the three bowls. You need to be able to put them in the freezer at exactly the same time, so you don't want to be moving your frozen food and drinks around later.

2. Think about what you know about ice. What temperature is water right before it freezes? You probably usually take baths in warm water. How quickly does the water turn cold when you're in the tub?

3.After considering different temperatures of water and ice, make a guess—called a hypothesis—answering the question: Does hot water freeze faster than cold water?

4. Write your hypothesis in your notebook, including whether you think the hot, warm, or cold water would freeze first and why.

5. Using your marker, write Hot on one of your sticky labels. Repeat with labels for Warm and Cold.

6. Place the sticky labels on each of the three bowls, using one per bowl. The labels will help you keep track of which bowl holds which temperature of water.

7. With your pencil, draw three columns in your notebook. Label the first column Hot, the second one Warm and the third Cold.

8.With the help of an adult, heat 1 cup of water to 100 degrees Fahrenheit. Pour it into the Hot bowl, being careful not to burn yourself.

9. Heat 1 cup of water to 70 degrees Fahrenheit, and pour it into the Warm bowl.

10.Fill the Cold bowl with water that's 40 degrees Fahrenheit.

11. Immediately place all three bowls in the freezer.

12. Record the starting temperatures in the correct columns of your notebook.

13. Open the freezer door every 10 minutes and take the temperature of the water in each bowl with a thermometer. Record the temperature in your notebook.

14. Repeat Step 13 until all three bowls have frozen over.

15. Compare the information in each of the three columns in your notebook. Was your hypothesis correct?

RESULTS/DATA: (claim/answer)The bowls that contain the hot and warm water will freezer faster than the bowl that is filled with cold water. (Evidence) all water evaporates, which means that the liquid (water) "disappears" and becomes a vapor, or gas. (the transfer of heat within the water as it moves around) plays a part in helping hot water freeze more quickly than the bowl of cold water. The hot water has more convection currents than cold water, causing it to cool down much more quickly.

5. (B) describing developments in the Native  American literary tradition.

6. (D) collection.

7. (B) helping to reshape Native American  literature.

Explanation:

The above are the correct answers.

From the passage, we discover that the passage is primarily concerned with the developments that took place in the Native American literary tradition. It revealed how Cook combined poetry and prose in her "Then The Badger Said" which introduced another approach in the Native American literary tradition. Hale and Silko added anew genre in the collection of literature by Native  American women.

These developments led to the reshaping of the Native Native American  literature.

"The Premature Burial", is a horror story written by American writer Edgar Allan Poe and it was published in 1850. This story is a reflection on the common occurence during the nineteenth century of people who suffer from some sort of disease that makes other people believe they are dead and are therefore buried alive. This fear, that of burial while still alive, feeds the terror of the main character of the story, who we know nothing about, except that he suffers from catalepsy and can sometimes look like he is dead. This narrator, then, talks about his fear, his illness and explains that fear by exposing several cases of buried people who were deemed dead when in truth they were still alive. This crippling fear, and especially one dream the narrator had, in which it seems he came face-to-face with death, inspires the character to take a series of steps to ensure that if he is discovered while in a trance, he is not buried alive, or if he is, he has a way to get out. But, then, at one point, the narrator still falls asleep, in a trance, and when he apparently wakes up, he thinks that his worst nightmare has been realized as he sees the wooden cover over his head and sees that all his preparations were useless because he has none with him. It seems that he was discovered dead far from home and simply placed on a coffin from which he thinks he cannot escape. Nevertheless the narrator screams and fights against his situation and finally is discovered by boatmen who tell him he just fell asleep under a boat. This occurrence forces the narrator to realize that his fear is useless and that he cannot plan against death. Soin the end, it seems that he is almost "cured" of his phobia.
