Answer:
The final pressure is 0.725 atm.
Explanation:
Gay Lussac's Law establishes the relationship between pressure and temperature of a gas when the volume is constant. This law says that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. That is, pressure and temperature are directly proportional quantities.
Mathematically, Gay-Lussac's law states that, when a gas undergoes a constant volume transformation, the quotient of the pressure exerted by the gas temperature remains constant:
![\frac{P}{T} =k](https://tex.z-dn.net/?f=%5Cfrac%7BP%7D%7BT%7D%20%20%3Dk)
When analyzing an initial state 1 and a final state 2, the following is satisfied:
![\frac{P1}{T1} =\frac{P2}{T2}](https://tex.z-dn.net/?f=%5Cfrac%7BP1%7D%7BT1%7D%20%20%3D%5Cfrac%7BP2%7D%7BT2%7D)
In this case:
- P1= 0.81 atm
- T1= 33 C= 306 K
- P2= ?
- T2= 1 C= 274 K
Replacing:
![\frac{0.81 atm}{306 K} =\frac{P2}{274 K}](https://tex.z-dn.net/?f=%5Cfrac%7B0.81%20atm%7D%7B306%20K%7D%20%20%3D%5Cfrac%7BP2%7D%7B274%20K%7D)
Solving:
![P2=274 K*\frac{0.81 atm}{306 K}](https://tex.z-dn.net/?f=P2%3D274%20K%2A%5Cfrac%7B0.81%20atm%7D%7B306%20K%7D)
P2= 0.725 atm
<u><em>The final pressure is 0.725 atm.</em></u>
Answer: At convergent boundaries, plates move toward each other. They can push together and cause mountain ranges to form. At other times, one plate gets pushed down beneath the other plate. ... At divergent boundaries, plates move apart from each other.
Explanation:
I whould personally go with plates moved in closer
Carbon has an electronic configuration of
1s² 2s² 2p²
Answer:
The kinetic energy of the molecule is greater than the attractive force between them. The kinetic molecular theory may be used to explain the behavior of solids and liquids.
Hope this helps, please let me know If I'm wrong.
The answer is TRUE.
If the Energy is on the left, then the problem is true. If it is on the right then it would be negative, false, and considered as exothermic.
Endothermic reaction = the products are higher in energy than the reactants.
Exothermic reaction = a chemical reaction that releases energy by light or heat.
