Which is most affected by a tropical warm air mass?

2 answers:

7 0

Air mass is defined as the mass of the huge body of air which develops over a specific region over time. Tropical warm air mass forms over the tropical area which is near to equator.

Miami, Florida lie closest to the equator, thus, it is most affected by tropical warm air mass.

Since, other three i.e. Charlotte, North Carolina; New York City, New York; Denver, Colorado are not closest to the equator. Thus, they are not most affected by the tropical warm air mass.

A gas has a volume of 1.75L at -23°C and 150.0 kPa. At what temperature would the gas occupy 1.30L at 210.0 kPa?

Nastasia [14]

Answer:

At -13 $^{0}\textrm{C}$ , the gas would occupy 1.30L at 210.0 kPa.

Explanation:

Let's assume the gas behaves ideally.

As amount of gas remains constant in both state therefore in accordance with combined gas law for an ideal gas-

$\frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{2}}{T_{2}}$

where $P_{1}$ and $P_{2}$ are initial and final pressure respectively.

$V_{1}$ and $V_{2}$ are initial and final volume respectively.

$T_{1}$ and $T_{2}$ are initial and final temperature in kelvin scale respectively.

Here $P_{1}=150.0kPa$ , $V_{1}=1.75L$ , $T_{1}=(273-23)K=250K$ , $P_{2}=210.0kPa$ and $V_{2}=1.30L$

Hence $T_{2}=\frac{P_{2}V_{2}T_{1}}{P_{1}V_{1}}$

$\Rightarrow T_{2}=\frac{(210.0kPa)\times (1.30L)\times (250K)}{(150.0kPa)\times (1.75L)}$

$\Rightarrow T_{2}=260K$

$\Rightarrow T_{2}=(260-273)^{0}\textrm{C}=-13^{0}\textrm{C}$

So at -13 $^{0}\textrm{C}$ , the gas would occupy 1.30L at 210.0 kPa.

2 questions, please help!!

Amanda [17]

i'd go for universal indicator, bromothymol blue and methyl red

i mean, they have the degrees of acidity (specific color changes)

they have wider ranges of color changes which will lead to the strength of acid

you will know the degree of acidity of the cosmetics

in fact, bromothymol blue is used to detect the slightest level of acid or base in a substance

universal indicator has the pH charts; the range is big so that you can measure the level of acidity effectively

methyl red is sensitive too as the other two mentioned earlier

the other way that's not included in your choices is the pH meter

unlike litmus papers which just have 2 results; either red or blue

phenolphthalein only colorless, pale pink

you won't know the degree of acidity

hope that helps

To test the quality of water sources in her area, Shameka collects five samples from each water source and tests the quality of

Blizzard [7]

Answer:

The answer is "Verification of results ".

Explanation:

The scientific system consisted inside an iterative or cyclical process which experimental results and technically confirm a theory. There are four things which scientific design aims people explain:

Subject of investigation characterization.
Hypothesis from its consequences of its characterization.
Forecasts.
Experimentation which show the precision and consistency of the hypothesis.

Its first stage of analysis involves collecting the samples taken for the current context, that are the focus of discussion, and then testing the samples taken to determine the absorbance of soft and hard salts throughout the water. It is required for water quality to be determined. Therefore, the collection and testing of samples falls under the scientific design category of classification, whereby Shamekha tried to verify the findings.
