Aballon is filled with 35 l of air at 2.0 atm. if the pressure is increase to 3.5 atm, what is the new volume?

20 L  

Step-by-step explanation:

Since temperature is constant, we can use Boyle’s Law.

p₁V₁ = p₂V₂    Divide each side by p₂

 V₂ = V₁ × p₁/p₂

Data:

p₁ = 2.0 atm; V₁ = 35 L

p₂ = 3.5 atm; V₂ = ?

Calculations:

V₂ = 35 × 2.0/3.5

V₂ = 20 L

Monosaccharides are the most basic units of carbohydrates. These are simple sugars, including glucose, fructose, and others. They contain between three and seven carbon atoms, have a sweet taste and are used by the body for energy.
