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

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
