Under Pressure

Paintball is a game that shoots out markers or paintballs, that when they hit, the markers explode causing a paint mark on a person, a piece of cover, and trees.Paintball is also a game where many people do different types of games like capture the flag to different battle scenarios. Before paintball was a game paintballs was used to mark cattle for shipping purposes. Many people play this game with pump guns. These guns have an air pump attached and also a hopper.The hopper is the top piece of…

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…

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…

says this, it shows how she did not mind her birthmark being there, never thinking it as a bad thing. Aylmer proposes a plan to Georgina about removing her birthmark. He then convinces her to say yes. This relates to the story Recipe because it goes under the same theme of society pressuring people to look beautiful by changing the way they are. This reading connects to the poem Recipe because in the poem the author is trying to show the readers how this girl is altering her beauty just to try…

the character’s situation and decide what we would do, learning more about ourselves. The message of this book is that peer pressure can lead to a path of destruction from the choices that you made, which will change your life forever making you someone you're not, close to a point of no return. Peer pressure is relevant because we see kids in society influenced by peer pressure who end up making the wrong decisions that go against morals, values,…

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…
