What is the pressure inside such a balloon (in atm) if it starts out at sea level with a temperature of 12.8°C and rises to an a

tatiyna

Answer:

The final pressure inside the balloon will be $P_2=0.0359\ atm$ .

Explanation:

Given initial temperature of the balloon is $T_1=12.8\°C$

And the final temperature of the balloon is $T_2=-47.7\°C$

Initially, the balloon is at atmospheric pressure $P_1=1\ atm$ and volume be $V_1$

And the final pressure in the balloon is $P_2$ and the volume be $V_2$

Also, it is given in the question that the final volume became twenty-two times the original volume.

We can write $V_2=22V_1$

Now, using ideal gas equation.

$\frac{P_2V_2}{P_1V_1}=\frac{nRT_2}{nRT_2}$

Where, $R$ is the gas constant. And $n$ is moles of substance inside the balloon.

In our problem the value of $n$ will be the same for both cases. Also, $R$ is the gas constant.

$\frac{P_2V_2}{P_1V_1}=\frac{T_2}{T_1}$

Also, we have $V_2=22V_1$ from the question.

$\frac{P_2\times 22V_1}{P_1V_1}=\frac{T_2}{T_1}\\\\\frac{P_2\times 22}{P_1}=\frac{T_2}{T_1}$

We need to convert the temperature from $\°C$ to Kelvin.

$T_1=12.8\°C\\T_1=12.8+273.15=285.95\\T_2=-47.7\°C\\T_2=-47.7+273.15=225.45$

Plug these values we get,

$\frac{P_2\times 22}{1}=\frac{225.45}{285.95}\\\\22\times P_2=0.789\\P_2=\frac{0.789}{22}\\P_2=0.0359\ atm.$

So, the final pressure inside the balloon will be $P_2=0.0359\ atm$ .

Of the three primary forms of subaerial volcanoes, ________ are large cone-shaped mountains that consist of alternating layers o

Alborosie

Answer:

Strato-volcano

Explanation:

Strato-volcanoes are usually characterized by the presence of steep-sided slopes, with distinct craters, and are frequently erupted and conical in appearance. This type of volcano is generally felsic in nature. Due to the presence of high silica content, the magma being highly viscous, moves at a relatively slower rate. These are highly explosive and produce a large number of pyroclastic materials, lava flow, volcanic ashes, and gases.

They are also commonly considered as the composite volcano, and are comprised of alternating tephra and solidified lava layers.

Which is the force of repulsion between two positivity-charged particles?

Yuki888 [10]

Since they are both positively charged, then the force would in fact be repulsion, because they are both the same. If you were to have one positively charged, and one negatively charged, then they would go towards eachother.

I hope this helps, if you need help on this question or any other questions, just ask. I am here to help.

I am drowning in his silence

damaskus [11]

Correct answer choice for question 1 is:

A) Figurative language

Explanation:

Figurative language uses terms of speech to be more powerful, effective, and impactful. Characters of speech such as metaphors, similes, and implications go away the usual meanings of the words to give users new acumens. On the other hand, alliterations, imageries, or echoes are symbolic tools that review the minds of the users. Figurative language can perform in various forms with the use of various literary and eloquent articles.

Correct answer choice for question 2 is :

D) Words that trigger the imagination to remember by appealing to the five senses

Explanation:

Imagery, in a literary text, is an author's use of rich and detailed language to add intensity to their work. It advances to human senses to increase the reader's knowledge of the work. Powerful kinds of comparison join all of the senses. There are seven main kinds of imagery, each resembling a sense, feeling, action, or reaction. Olfactory imagery concerns, scents, or the sense of smell. Gustatory imagery concerns tastes or the sense of taste. Tactile imagery concerns physical forms or the feeling of touch.
