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…

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…

High Blood Pressure Gisselle Nogueira Essay 2 Final Version High blood pressure, scientifically known as hypertension is a very common disease in adults. This happens when blood flows through blood vessels at higher than normal pressures. There are different causes to this disease. Some include smoking, diet with a lot of sodium, and poor physical activity. Although it is hereditary, there are ways to prevent complications from hypertension like a heart attack, dementia, and…

transmission. The odometer is one important federal device that cannot be changed. It is controlled by a stepper motor that runs when the vehicle is in motion. The information on there cannot be changed. The next is the oil pressure gauge. It tells you if you have enough oil pressure for the engine to operate efficiently. Normal operating is between 45 to 75 psi while the engines is operating and at the correct temperature. The coolant gauge gives you the temperature of the engines cooling…

It is easy for us to neglect the immediate and colossus problems plaguing our world, because the biggest problems, the ones that affect not only our future generations here in America, but the future generations across the globe, seem like they are flames, too bright to look at. We know it is there, yet instead of trying to put out the fires, we turn away, hoping someone else will eventually do it for us. One of the biggest, if not the biggest, flame destroying our world is the unbelievably high…

28g, the mass mixing ratio would be lower than the volume mixing ratio. a) m=F/a m=101300/9.8=10,336 An estimate of the total mass of a column of the atmosphere with a base area of 1m2 is 10,336kg. b) for a 1m2 column at average surface pressure of 985mb: m= 98500/9.8=10,051 kg Surface area of the Earth: 4π (6370)^2=509,904,363.8 =5.1 x 〖10〗^8 〖km〗^2 =5.1 x 〖10〗^14 m^2 5.1x〖10〗^(14 ) x 10,051=5.13 x 〖10〗^18 kg The…
