Atmospheric pressure

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…

The pause is caused when the pressure in the lungs is equal to the atmospheric pressure. Inspiration starts when chemoreceptors sense there is a high amount of CO2 in the blood, which then tells the body to contract the diaphragm and external intercostal muscles to contract, which increases the volume of the thoracic cavity. Due to this increase in volume of the thoracic cavity, and decrease in pressure, the air will wants to move to an area where there is less pressure, which is inside your…

The sphygmomanometer is used to read our blood pressure. Many of us are aware of this medical machine because we get our blood pressure checked at the doctor’s office. This is important to us because it can let us know of any heart complications such as high blood pressure, strokes, heart attacks, or kidney disease. All of these are preventable if caught in time with a doctor’s supervision and medication. Although many of us have seen this device there is a process to using this medical…

into happenings on a molecular level in the (DIWF) with the aid of experimental evidence. The writer is keen on proving that the fog produced in the (DIWF) demonstration is actually from the bulk water onto which the dry ice is placed and not the atmospheric water vapor. In a bid to understand the mechanism of the formation of fog, the writer employs a model, where the interaction of dry ice with other liquids is closely observed, and the effectiveness of experimental conditions in producing…

blood pressure, the volume of blood, and the fluid and electrolyte balance in the body. Angiotensin II controls vasoconstriction in the circulatory system, which increases blood pressure and can cause hypertension (Burchum and Rosenthal, 2016,p.471-473). Aldosterone is what controls the fluid and electrolyte balance in the body. It also is released from the adrenal cortex and activates retention of sodium, which increases the fluid volume, which consequently increases the blood pressure…

Hypertension is an asymptomatic vascular disorder that displays an increased systolic (>120mm/Hg) or diastolic (>80mm/Hg) pressure. The etiology of the disorder is unknown, and is therefore known as an idiopathic disorder but a variety of factors do play a role in the pathogenesis of the disorder such as coarctation of the aorta, salt sensitivity, renal abnormalities, hormonal disorders and neurological malfunctions. Therefore, the manifestation of the disorder is a complex interaction…

Hypertension, sometimes known as “Silent Killer” is America’s freighting combative illness we struggle to regulate. Due too many health risk factors, many people are sometimes unaware of hypertension until suffering from severe damaging effects. High blood pressure is a growing problem in today’s life controlling it is the key priority. According to statistics approximately 50 million lives in the United States are affected by hypertension and approximately 1 billion worldwide. In this paper,…

Hypertension- high blood pressure means that the systolic blood pressure is consistently over 140 (represent the pressure generate when the heat beat) and the diastolic blood pressure is consistently over 90 (represent the pressure in the vessels when the heart is at rest). Pre-hypertension will eventually lead to hypertension, those with a systolic pressure between 120 and 139, and a diastolic between 80 and 89 on multiple readings (“Hypertension,” n.d. ). This is a condition in which the force…
