Answer:
Initial temperature = T₁ = -96.65 °C
Explanation:
Given data:
Initial volume = 4.5 L
Final temperature = 80°C (80+273 = 353 K)
Final volume = 9.0 L
Initial temperature = ?
Solution:
According to Charles law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
T₁ = V₁ T₂/V₂
T₁ = 4.5 L × 353 K / 9.0 L
T₁ = 1588.5 L.K / 9.0 L
T₁ = 176.5 K
Kelvin to °C:
176.5 K - 273.15 = -96.65 °C
Answer:
nitrogen, oxygen, argon, carbon dioxide, neon, helium, krypton, hydrogen, and xenon. It does not include water vapor because the amount of vapor changes based on humidity and temperature.
Answer:
The correct answer is 3.6 L
Explanation:
According to the gases Boyle's law, the relation between the volume and the pressure of a gas at constant temperature is given by the following mathematical expression:
Pi x Vi = Pf x Vf
Where Pi and Vi are the <u>initial </u>pressure and volume of the gas whereas Pf and Vf are the <u>final</u> pressure and volume, respectively.
In this problem we have:
Vi = 18.0 L
Pi= 902 Torr
Pf= 4510 Torr
The final volume (Vf) will be:
Vf = (Pi x Vi)/Pf = (902 Torr x 18.0 L)/4510 Torr= 3.6 L
From the result, we can see that if the pressure increases, the volume of the gas decreases.
