Answer: Complete in order

1. Define key vocab words

2. Read the 6 paragraph article

3. Answer Higher Level Thinking questions

Explanation:

1. Give a very short definition for the vocab words (couple of words or less) but still try to remember the whole original definition

- make sure it makes sense to you

2. Read quickly (skim) the article and highlight or circle vocab words

-pay attention to the first and last sentence of each paragraph

- Go back and read the article more closely

- After each paragraph, write in one sentence something you learned or think is important (take-away sentence)

- Tell someone each of your take-away sentences and get their feedback ( do they agree or disagree?)

3. Answer the questions thoughtfully (put time into them)

- Long, thought out answers

- Use your knowledge of the article to answer them

3. A 31.2-g piece of silver (s = 0.237 J/(g · °C)), initially at 277.2°C, is added to 185.8 g of a liquid, initially at 24.4°C,

VARVARA [1.3K]

Answer:

$Cp_{liquid}=2.54\frac{J}{g\°C}$

Explanation:

Hello,

In this case, since silver is initially hot as it cools down, the heat it loses is gained by the liquid, which can be thermodynamically represented by:

$Q_{Ag}=-Q_{liquid}$

That in terms of the heat capacities, masses and temperature changes turns out:

$m_{Ag}Cp_{Ag}(T_2-T_{Ag})=-m_{liquid}Cp_{liquid}(T_2-T_{liquid})$

Since no phase change is happening. Thus, solving for the heat capacity of the liquid we obtain:

$Cp_{liquid}=\frac{m_{Ag}Cp_{Ag}(T_2-T_{Ag})}{-m_{liquid}(T_2-T_{liquid})} \\\\Cp_{liquid}=\frac{31.2g*0.237\frac{J}{g\°C}*(28.3-227.2)\°C}{185.8g*(28.3-24.4)\°C}\\ \\Cp_{liquid}=2.54\frac{J}{g\°C}$

Best regards.

Why does the sky change colors at sunrise and sunset

aniked [119]

Answer:

As the sun's angle changes, (because of the rotation of the earth) the sun slowly begins to shine more or less sunshine slowly. When sunsets and sunrises occur, the color of the sky changes because the sunshine is starting to fade out or in.

I put it in my own words so you don't have to worry about plagiarism :)
