If you have a gas sample with an initial pressure of 16 atm, an initial volume of 20 L and a temperature of 500 K, what will the
DiKsa [7]

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

lbvjy [14]

Answer:

Oxygen

Explanation:

 · Air decolorization makes use of chromophores’ instability on oxygen to decolorize the oil by air-oxidizing pigments. For example, the carotenoid and chlorophyll in the oil are very unstable because of their structure, which is easy to be discolored under the action of oxygen. However, air decolorization leads to thermal oxidation of the oil, too.
