The average molar mass is approx. 750,000 g/mol. Description: Milky-white liquid of low viscosity with a faint characteristic odour. It is highly permeable polymer and is very flexible polymer. It is available in the 40% dispersion form and it already contains plasticizer, so there is no need to add plasticizer in the formulation containing Eudragit NE 40
The other process was osmosis. Osmosis is the diffusion of water through a membrane from an area of high contraction to an area of low concentration. Osmosis happens in three different environments. Osmosis is like diffusion in it requiring no energy. Osmosis can happen in three different types of environments; Hypertonic, Isotonic and Hypotonic.
Chemical level – this is the simplest level where it involves the building blocks of matter called atoms. Atoms link together in different patterns to build molecules that perform important functions of life. Molecules are combined to build cellular organelles which are called the inner organ of a cell. 2. Cellular level – which is the smallest unit of living matter (combined of cells).
Nobody is quite sure exactly what it is, except that it’s a fundamental property of matter, existing in 2 opposite polarities called positive and negative. Protons, 1 of 2 particles in atomic nuclei, are positive, while neutrons have no charge. Orbiting around the nucleus are electrons, the same number as protons inside the nucleus. Although electrons have 1,836 times less mass than protons, an electron has an equal (but opposite) charge (positive). Because they’re light and positioned outside the nucleus, electrons are much more easily dislodged from atoms than protons, so they’re the crucial carriers of electric charge.
Emma Rosandich Mahziar Sakiani Period 1 Bubble Lab Report Background Research: Bubbles are basically a very thin film of soapy water that is enclosing air that forms a hollow sphere with an iridescent surface. The surface of water in made of hundreds of molecules that stick tightly together because of intermolecular forces and surface tension. Surface tension helps the bubble keep its shape. Soap molecules have two ends- one end that sticks to water, and the other that is repelled by water. Bubbles are round because they are ‘minimal surface structures’, which means that bubbles hold the least possible surface area they can.
Titanium and its alloys react with interstitial elements such as oxygen, nitrogen, and hydrogen, below their respective melting points. In its reactions with other elements, titanium may form solid solutions and compounds with metallic, covalent or ionic bonding. Major alloying elements, added to improve mechanical properties and corrosion resistance, are classified as α-stabilizer, or β-stabilizers.The alloying elements are generally classified into three categories as α-stabilizer, β-stabilizer and neutral. The α-stabilizing elements extend the α phase field to higher temperatures, while β-stabilizing elements shift the β phase field to lower temperatures.
The first similarity is that both involve movement of molecules from an area of higher concentration to an area of lower concentration. This is to create the equal state and to even out the solute concentration in the area that doesn’t have as many water molecules. Secondly, both osmosis and diffusion are passive transports, meaning that they do not require energy. They happen naturally. The first difference between osmosis and diffusion is that osmosis is purely directed to the movement of water molecules, while diffusion can be directed toward the movement of any molecule or substance.
The lines which can be drawn at any flow field with the inclination of μ are said Mach lines of Mach waves. In the nonuniform flow field, μ varies with M and the Mach lines are curved. In the field of fluid flow at any point P, there is always two lines which intersect the streamline at the angle μ. Considering in the three- dimensional flow, the flow of supersonic stream is always associated with two families of mach lines represented in plus and minus signs. The mach lines with + sign run to the right of the streamline when viewed through the flow direxn and the lines with “–“ sign run to the left.
ΔH= q Specific heat is the amount of heat needed to raise the temperature of one gram of a substance by 1 C (or 1 K).1 Specific heat of water is equal to 4.18 J/ g℃.1 In order to determine the specific heat capacity of metal, it is necessary to know mass and change in temperature, specific heat of water, also change in temperature and mass of metal used: q_(H_2 O)=〖S.H.〗_(H_2 O) × m_(H_2 O) × ∆t_(H_2 O)= -〖S.H.〗_M × m_M ×
