Answer:
increased, 7.5-8.3 atm; decreased, 3.5-4.3 atm; Gay-Lussac's Law
Explanation:
1. The collision of gas molecules, results in the pressure increases.
2. The pressure of the system with an increase in the temperature has been 7.2-8.2 atm.
3. The pressure of the system with a decrease in the temperature has been 3.6-4.1 atm.
4. The relationship between the molecules has been given by Gay-Lussac's Law.
The relationship between the temperature and pressure has been given in the gaseous molecules with the ideal gas equation.
1. The temperature has been directly proportional to the temperature. Thus, with an increase in pressure, there has been an increase in temperature and vice versa.
With the collision of the gas molecules with the wall, there has been the liberation of the energy that increases the temperature. The increase in temperature mediates the increase in pressure.
Thus, with the collision of gas molecules, the pressure increases.
2. The relationship between the pressure and temperature has been given as:
[tex]\dfrac{P1}{T1}=\dfrac{P2}{T2}[/tex]
The initial temperature [tex]T1=300\;\text K[/tex]
Final temperature [tex]T2=400\;\text K[/tex]
Initial pressure, [tex]P1=5.4-6.2\;\text {atm}[/tex]
Final pressure, [tex]P2[/tex]
Substituting the values for calculating P2 as:
[tex]\rm \dfrac{5.4-6.2\;atm}{300\;K}=\dfrac{P2}{400\;K}\\\\\textit P2 = \dfrac{5.4-6.2\;atm}{300\;K}\;\times\;400\;K\\\\\textit{P}2=7.2-8.2\;atm[/tex]
The pressure of the system with an increase in the temperature has been 7.2-8.2 atm.
3. The pressure with the reduction of temperature has been given by :
[tex]\dfrac{P1}{T1}=\dfrac{P2}{T2}[/tex]
The initial temperature [tex]T1=400\;\text K[/tex]
Final temperature [tex]T2=200\;\text K[/tex]
Initial pressure, [tex]P1=7.2-8.2\;\text {atm}[/tex]
Final pressure, [tex]P2[/tex]
Substituting the values for calculating P2 as:
[tex]\rm \dfrac{7.2-8.2\;atm}{400\;K}=\dfrac{P2}{200\;K}\\\\\textit P2 = \dfrac{7.2-8.2\;atm}{400\;K}\;\times\;200\;K\\\\\textit{P}2=3.6-4.1\;atm[/tex]
The pressure of the system with a decrease in the temperature has been 3.6-4.1 atm.
4. The relationship between the molecules has been given by Gay-Lussac's Law. The law states that pressure has been directly proportional to the absolute temperature of the system.
