If the volume of a cylinder is reduced from 8 L to 4 L the pressure of the gas in the cylinder will change from 70 kilopascals to 140 KPa.

Explanation:

Given data:

Initial volume = 8 L

Final volume = 4 L

Initial pressure = 70 KPa

Final pressure = ?

Solution:

According to Boyles law:

P₁V₁ = P₂V₂

P₂ = P₁V₁ / V₂

P₂ = 70 KPa × 8 L/  4 L

P₂ = 560 KPa. L/4 L

P₂ = 140 KPa

If the volume of a cylinder is reduced from 8 L to 4 L the pressure of the gas in the cylinder will change from 70 kilopascals to 140 KPa.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.
