Answer #1

The plasma treatment with oxygen on a polylactic (PLA) material will lead to a more hydrophobic surface mainly because of the topographical changes in the material. the roughness in the surface of maerial of the fibres (which is assumed tobe a PLA fabric) will enhance hence making it more hydrophobic.

Polylactic acid is an aliphatic and biodegradable polymer which is obtained completely from renewable sources.It is having good fibre- and film-forming properties but due to its low melting point and high surface friction it limit its applications in many areas.

Estimate the mole ratio of O2 to the sample(benzoic acid, sucrose) and compare the estimate with the stoichiometric ratio for the combustion. The volume of the bomb is 0.3dm^3. Use T=300K and 30atm for the pressure of O2. As a first approximation use the ideal gas law, but more a more refine estimate, use the compressibility factor for O2 at 30atm and 300K as calculated from the Van der Waals equation. Assume ideal behaviour on the part of oxygen. Combustion...
