Answer:

A sample of a gas (5.0 mol) at 1.0 atm is expanded at constant temperature from 10 L to 15 L. The final pressure is 0.67 atm.

Step by Step Explanation?

Boyle's law states that in constant temperature the variation volume of gas is inversely proportional to the applied pressure.

The formula is,

P₁ x V₁ = P₂ × V₂

Where,

P₁ is initial pressure = 1 atm

P2 is final pressure = ? (Not Known)

V₁ is initial volume = 10 L

V₂ is final volume = 15 L

Now put the values in the formula,

\begin{gathered}\rm 1\times 10 = P_2\times 15\\\\\rm P_2 = \frac{10}{15\\} \\\\\rm P_2 = 0.67\end{gathered]

Therefore, the answer is 0.67 atm.

Determine the latitude and longitude of the location A
malfutka [58]

Answer:

Latitude: 30\° N

Longitude: 45\° W

Explanation:

Lets begin by explaining the meaning of latitude and longitude as geogrephical coordinates:

Latitude is the angular distance between the equatorial line, and a specific point on the Earth. It is measured in degrees and is represented according to the hemisphere in which the point is located, which can be north or south latitude.  

In this sense latitude 0\° refers to the equatorial line that divides the Earth in two hemispheres (North and South).

Longitude represents the specific east–west position of a point on the Earth's surface, being longitude 0\° the prime meridian or Greenwich meridian.

So, according to the figure, where the model of the Earth is divided by latitude lines separated by 10\° and the longitude lines separated by 15\°; we only have to count the lines from the equator to the line where the point A is, and count the lines fromo the Prime meridian to the line where point A is located.

Hence, point A location is:

Latitude: 30\° N

Longitude: 45\° W

A student sets up the following equation to convert a measurement.
dybincka [34]

Answer:

\frac{1 m}{100 cm}

Explanation:

The final answer has a different set of units. In particular, meters (m) changes to centimeters (cm). To make this change, you need to multiply the first value by proportions.

When writing these proportions, it is important that they are arranged in a way that allows for the cancellation of units. For instance, since m is located in the denominator, it must be located in the numerator of the conversion.

<u>Proportion:</u>

1 m = 100 cm

The full expression:

<h3>-1.7*10^5\frac{V}{m}  ·  \frac{1 m}{100 cm}  =  ? \frac{V}{cm}</h3><h2>                 ^</h2>

As you can see, the old unit (m) cancels out and you are left with cm in the denominator.
