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
Primary pollutants affect the world more than secondary pollutants
Explanation:
The electromagnetic spectrum shows the wavelength or frequency range of different waves starting from gamma rays to radio waves.
In the electromagnetic spectrum, gamma rays have shorter wavelength while radio wave have longest wavelength.
The correct order is as follows :
(A) Gamma rays
(B) X rays
(C) Ultraviolet
(D) Visible light
(E) Infrared waves
(F) Radio waves
So, the correct order form left to right in order of increasing wavelength is as follows :
Gamma rays < X rays < Ultraviolet < Visible Light < Infrared Waves < Radio Waves
Answer:
this is their property and that's also what's make it a metal
