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.

Answers

Answer:For VOA Learning English, this is Everyday Grammar.

There is an old saying that America and Britain are “two nations divided by a common language.”

No one knows exactly who said this, but it reflects the way many Brits feel about American English. My British friend still tells me, “You don’t speak English. You speak American.”

But are American and British English really so different?

Vocabulary

The most noticeable difference between American and British English is vocabulary. There are hundreds of everyday words that are different. For example, Brits call the front of a car the bonnet, while Americans call it the hood.

Americans go on vacation, while Brits go on holidays, or hols.

New Yorkers live in apartments; Londoners live in flats.

There are far more examples than we can talk about here. Fortunately, most Americans and Brits can usually guess the meaning through the context of a sentence.

Collective nouns

There are a few grammatical differences between the two varieties of English. Let’s start with collective nouns. We use collective nouns to refer to a group of individuals.

In American English, collective nouns are singular. For example, staff refers to a group of employees; band refers to a group of musicians; team refers to a group of athletes. Americans would say, “The band is good.”

But in British English, collective nouns can be singular or plural. You might hear someone from Britain say, “The team are playing tonight” or “The team is playing tonight.”

Auxiliary verbs

Another grammar difference between American and British English relates to auxiliary verbs. Auxiliary verbs, also known as helping verbs, are verbs that help form a grammatical function. They “help” the main verb by adding information about time, modality and voice.

Let’s look at the auxiliary verb shall. Brits sometimes use shall to express the future.

For example, “I shall go home now.” Americans know what shall means, but rarely use it in conversation. It seems very formal. Americans would probably use “I will go home now.”

In question form, a Brit might say, “Shall we go now?” while an American would probably say, “Should we go now?”

When Americans want to express a lack of obligation, they use the helping verb do with negative not followed by need. “You do not need to come to work today.” Brits drop the helping verb and contract not. “You needn’t come to work today.”

Explanation:

The question wants to analyze your writing skill. For that reason, I can't write your essay, but I'll show you how to do it.

First, as the question suggests, you must choose one of the subjects presented in the question. Then you must research this subject, create associations, develop arguments and data.

After that, you can write your essay.

Steps to write an essay:Introduction: Introduce the subject of your essay and provide introductory information that stimulates the reader.

Body: Write between two or three paragraphs. In these paragraphs, you will develop the subject of your essay, showing relevant information that should be known to your readers.

Conclusion: Summarize everything you presented and reinforce the importance of the subject addressed.

Opened sentences with discourse markers?

Answers

Discourse markers are words or phrases like anyway, right, okay, as I say, to begin with. We use them to connect, organise and manage what we say or write or to express attitude:

[friends are talking]

A:

So, I’ve decided I’m going to go to the bank and ask for a car loan.

B:

That sounds like a good idea.

C:

Well, you need a car.

B:

Right.

A:

Anyway, I was wondering if either of you would teach me how to drive.

The discourse markers in this extract have a number of uses:so marks the beginning of a new part of the conversation.

well marks a change in the focus (from getting a car loan to needing a car).

right marks a response (B is agreeing with C).

anyway marks a shift in topic (from buying a new car to having driving lessons).

We use different discourse markers in speaking and writing. In speaking, the following discourse markers are very common:

anyway

like

right

you know

fine

now

so

I mean

good

oh

well

as I say

great

okay

mind you

for a start

In writing, the following discourse markers are common:

firstly

in addition

moreover

on the other hand

secondly

in conclusion

on the one hand

to begin with

thirdly

in sum

Discourse markers do not always have meanings that you will find in your dictionary. However, they do have certain functions, and some discourse markers, such as well, can have a number of functions.

:)

'Marjorie, Russ said, “You wouldn't happen to know any lawyers, would you?, ending to the scene create the most suspense, hence option D is correct.

What is the suspense of ending scene?

The most suspenseful scene because it started with Russ instructing Marjorie to pay close attention, which immediately grabs her attention and makes her want to hear what he has to say.

He continues by informing her that she needs to know something. Marjorie had been waiting for Russ to call all day.

This is the deciding moment because it creates the most tension when he tells her to pay close attention after commanding her to do so earlier in the scenario.

Therefore, 'Marjorie, Russ said, You wouldn't happen to know any lawyers, would you? Is correct option.

When Nick first meets Catherine, in chapter 2, she tells him that neither Myrtle nor Tom can stand their spouses. She also said that Daisy refused to get a divorce because she was Catholic.

What would you have done, if you were Nick?

Answers

Answer:

This tells us that Nick is either afraid of her, or of ruining their relationship. Another reason why he might have not called her out on it is that he finds those things trivial and doesn't care enough. He doesn't want to call her out on it because it could hurt her feelings and cause her to be angry with him. If I were Nick, and if it was that important to me, I would have carefully asked her, but not outright or bluntly.

Specifically, the study addressed whether or not female deer play a role in choosing their mates. He further pointed out that over time there is optimization of traits, and because antlers require a huge nutritional investment, bucks can’t afford to invest more than what’s needed to grow an adequate set of antlers necessary for armament.
