Osmotic pressure

Solubility property of ozone is dependent on several extrinsic factors such as temperature, pressure, composition of the medium, pH, gas flow rate, etc. Henry’s law says that the pressure of the gas exerts above the liquid is directly proportional to the solubility of the ozone (Bablon et al., 1991). De Smedt et al. (2001) revealed that solubility of ozone is dependent on pH, temperature and type of additives of the aqueous solution. Levanov et al. (2008) found that solubility of ozone decreased…

A water jet cutter, commonly called a water jet, is a tool that uses a very high-pressure jet of water or a mixture of water and an abrasive to cut a wide variety of materials. A water jet that does not use abrasives is referred to as a pure water jet or water-only cutting [1]. For a pure water jet (Figure 1) the water is pressurized to the range of 20 - 94 ksi, 138 - 649 MPa at the inlet and forced through an orifice with a diameter of between 0.25 - 4 mm creating a very thin high velocity…

Ferroelectricity Among the ferroelectric materials, the static dielectric constant depends on the temperature under the relation: Curie – Weiss relation: €r = P + Q/ (T-Tc), (T> Tc), P, Q are constants temperature independent. C = Curie constant Tc = Curie temperature A transition in phase is observed at temperature Tc. Above this, the material remains in Paraelectric phase (the phase where the elementary dipoles of different crystal unit cells are…

Simulator. PVT is an acronym for Pressure, Temperature, and Volume. The PVT Simulator is a program on the computer called PVTLab. Phase behavior experiments can be done using an actual PVT apparatus but they are very expensive and the experiments would take hours to complete. With the simulator one can easily imitate a real world scenario and it takes only mere minutes to complete an experiment. The class was given the task of finding the bubble point and dew point pressures of pure Carbon…

variables of state of an ideal gas with the following equation: P V = n R T, where P is the pressure of the gas in atmospheres, V is the volume of the gas in liters, n is moles of the gas, and T is the temperature of the gas in Kelvin degrees. R is the ideal gas constant. The Ideal Gas Law is a combined summary of Boyle’s Law, Charles’s Law, and the Avogadro’s Law. This Law works best under low pressure, room temperature (298K) environments because these environments allow gases to behave…

effects. Firstly, there are losses through the viscous effects between the solid matrix and the fluid when pressure waves causes the fluid to move longitudinally [3]. Secondly, pressure waves causes the skeletal structure…

Aim: To use a neutralization reaction to propel a model rocket. Hypothesis: That the neutralization reaction between the bicarbonate of soda and the vinegar will produce a gas, which build up enough pressure to launch the bottle rocket. Materials: Vinegar, bicarbonate of soda (NaHCO3) Equipment: Plastic Bottle, Wooden Block, Nail, Cork, Duct Tape. Method: 1. Nailed a cork to plank of wood as a base for the rocket. 2. Wrapped tape around cork so that it fitted the neck of the bottle. 3. Put two…

The Noble Gas Equations By: Andy Jiang There is a pattern in the atomic numbers of Noble Gasses. The atomic of Noble Gasses aren't arbitrary or random. They have beautiful equations, which I have derived, that gives the atomic number of a Noble Gas based on what period it is in. Theoretically, my equations can work beyond the 7th period. The fact that there is an underlying pattern among the atomic number of Noble Gasses, something seemingly arbitrary, is a property of our mathematical,…

Experiment #3 (Gas) a). My first hypothesis was correct. I had a hypothesis of the glove inflating when the flask was put in the hot water because I knew that gasses with more thermal energy tend to go upwards and I assumed that the heat would make the gas particles inside the bottle expand and inflate the glove when there is no more space in the bottle My second hypothesis was also correct. I had a hypothesis of the glove deflating when the flask was put in ice because I knew that when…

system eliminates or keeps the excess or shortage solutes or water. When water intake is not enough, blood volume decreases, blood pressure goes down, and this leads the renin secretion which promotes releasing of angiotensin II for increasing osmotic pressure to stimulate hypothalamus. Also water loss is regulated by ADH with water reabsorption mechanism. When osmotic pressure increased ADH also secreted to promotes absorbing water from the collecting ducts causing the produce of concentrated…
