Sagot :
Answer:
The pressure will be 4.27 atm.
Explanation:
Gay-Lussac's law can be expressed mathematically as follows:
[tex]\frac{P}{T} =k[/tex]
Where P = pressure, T = temperature, K = Constant
This law indicates that the quotient between pressure and temperature is constant.
This law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.
In short, 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.
You want to study two different states, an initial state and a final state. You have a gas that is at a pressure P1 and a temperature T1 at the beginning of the experiment. By varying the temperature to a new value T2, then the pressure will change to P2, and the following will be fulfilled:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case:
- P1= 4 atm
- T1= 20 C= 293 K (being 0 C= 273 K)
- P2= ?
- T2= 40 C= 313 K
Replacing:
[tex]\frac{4 atm}{293 K} =\frac{P2}{313 K}[/tex]
Solving:
[tex]P2= 313 K* \frac{4 atm}{293 K}[/tex]
P2= 4.27 atm
The pressure will be 4.27 atm.
