Given the data from the question, the final temperature is 200 K, while pressure remains constant.
<h3>Basic concepts </h3>
To obtain the correct answer to the question, we shall consider two conditions:
- Case 1 (temperature is constant)
- Case 2 (pressure is constant)
<h3>Case 1 (Temperature is constant) </h3>
We shall determine the new pressure by using the combined gas equation (P₁V₁ / T₁ = P₂V₂ / T₂) as illustrated below:
- Initial volume (V₁) = 3 L
- Initial pressure (P₁) = 1 atm
- Temperature = constant
- New Volume (V₂) = 2 L
- New pressure (P₂) =?
P₁V₁ / T₁ = P₂V₂ / T₂
Since temperature is constant, we have:
P₁V₁ = P₂V₂
3 × 1 = P₂ × 2
3 = P₂ × 2
Divide both side by 2
P₂ = 3 / 2
P₂ = 1.5 atm
<h3>Case 2 ( pressure is constant) </h3>
We shall determine the new temperature by using the combined gas equation (P₁V₁ / T₁ = P₂V₂ / T₂) as illustrated below:
- Initial volume (V₁) = 3 L
- Initial pressure (T₁) = 300 K
- Pressure = constant
- New Volume (V₂) = 2 L
- New pressure (T₂) =?
P₁V₁ / T₁ = P₂V₂ / T₂
Since pressure is constant, we have:
V₁ / T₁ = V₂ / T₂
3 / 300 = 2 / T₂
1 / 100 = 2 / T₂
Cross multiply
T₂ = 100 × 2
T₂ = 200 K
SUMMARY
- when the temperature is constant, the new pressure is 1.5 atm
- When the pressure is constant, the new temperature is 200 K
From the calculations made above, we can conclude that the correct answer is:
The final temperature is 200 K, while pressure remains constant.

Hi there!
Rutherford's experiment showed that the atom's nucleus <em>did </em>have a positive charge. The α particles' trajectory was altered when it went through the gold foil, which, in turn resulted in the discovery of the atom's positive charge.
I hope this helps!

Answer:
The molarity of the solution is 0.29 ![\frac{moles}{liter}](https://tex.z-dn.net/?f=%5Cfrac%7Bmoles%7D%7Bliter%7D)
Explanation:
Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species. It is defined as the number of moles of solute that are dissolved in a given volume.
Molarity is calculated as the quotient between the number of moles of solutes and the volume of the solution:
![Molarity=\frac{number of moles of solute}{volume}](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7Bnumber%20of%20moles%20of%20solute%7D%7Bvolume%7D)
Molarity is expressed in units
.
In this case:
- number of moles of solute= 2.1 moles
- volume= 7.3 liters
Replacing:
![Molarity=\frac{2.1 moles}{7.3 liters}](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7B2.1%20moles%7D%7B7.3%20liters%7D)
Molarity= 0.29 ![\frac{moles}{liter}](https://tex.z-dn.net/?f=%5Cfrac%7Bmoles%7D%7Bliter%7D)
<u><em>The molarity of the solution is 0.29 </em></u>

Chemiosmosis is the development of particles over a semipermeable layer, down their electrochemical angle. A case of this would be the era of adenosine triphosphate by the development of hydrogen particles over a film amid cell breath or photosynthesis.
