Give two other factors that may contribute to the occurrence of cardiovascular
disease.

High blood pressure. High blood pressure (hypertension) is one of the most important risk factors for CVD.

High cholesterol - High-fat diet.

Ideal Gas Law ( PV = nRT)

Explanation:

Using the Ideal Gas Law, we have; PV = nRT

Where P= Pressure = ?

            V= Volume = 8.0 L

            n =  moles = 8.0

            R =  Gas constant = 0.0821 L.atm/mol/K

            T =  80° c + 273 =  353.15K

Therefore Pressure would be;  P = nRT/ V =  8 x 0.0821 x 353.15 / 8 = 28.9atm
