A sample of fluorine gas occupies 0.810 L at 270 K and 1 atm. What volume does the gas occupy when the pressure is doubled, and the temperature increases to 400 K?

V₂ = 0.6 L

Explanation:

Given data:

Initial volume of gas = 0.810 L

Initial temperature = 270 K

Initial pressure = 1 atm

Final volume = ?

Final pressure = 2 atm

Final temperature = 400 K

Solution:

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Solution:

V₂ = P₁V₁ T₂/ T₁ P₂  

V₂ = 1 atm × 0.810 L × 400 K / 270 K × 2 atm  

V₂ = 324 atm .L. K / 540 atm.K

V₂ = 0.6 L

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
