Answer:
T₂ = 218.75 K
Explanation:
Given data:
Initial volume = 20 L
Initial pressure = 16 atm
Initial temperature = 500 K
Final temperature = ?
Final volume = 35 L
Final pressure = 4 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
by putting values,
P₁V₁/T₁ = P₂V₂/T₂
T₂ = P₂V₂ T₁/ P₁V₁
T₂ = 4 atm × 35 L × 500 K / 16 atm × 20 L
T₂ = 70000 atm .L. K / 320 atm.L
T₂ = 218.75 K
C) They have a large number of rods and small number of cones.
yes because they are inert or inactive at normal temperature, they are inactive because their outer most orbit contain either 2 or 8 electrons.that make them stable
