Answer:
The final volume is 1.1 L.
Explanation:
Given data:
Initial pressure of gas = 125 KPa
Final pressure of gas = 375 KPa
Initial volume = 3.3 L
Final volume = ?
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
125 Kpa × 3.3 L = 375 Kpa × V₂
V₂ = 412.5 KPa. L/375 Kpa
V₂ = 1.1 L
The volume of gas is reduced to the 1.1 L because of increasing pressure.
Answer:
To have a high electrical conductivity, a normal metal should have mobile valence electrons and a long electron mean free path.
Explanation:
A long mean free path means that the electron goes a long distance between scattering events.
