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.
The potential energy is converted into kinetic energy once it falls downhill. In thermal energy or heat energy is how fast the particles of something are moving. The more temperature you have, the more thermal energy you have which means the particles will be much faster. A hot cup of coffee has lots of thermal energy unlike a cold beverage. In chemical energy, think ability of your body to do work.
Among four types of surfactants, partially hydrolyzed PVA is most frequent used because it gives the smallest microsheres (Jeffrey et al, 1991). The amount of PVA used may affect microparticles properties. Freitas and coworkers have added 1.3% and 8% of PVA into an aqueous solution and found that both lower and higher concentrations of surfactant results in coagulation of the particles. Hence, these authors suggested to use 3% of PVA as it the most optimum concentration. (Freitas and Marchetti,
Once this is done, object 1 may be removed and replaced with the rubber stopper having more mass than the first one. (object 2) Note that, because the width of the stopper is more it will require more string to go through the holes and tie it. Using a metric ruler re-adjust the radius, ensuring that it the exact same radius as the first, 18.9cm. Make sure all the safety procedures are followed, then begin your experiment Hold the tube and swing the stopper in a circular motion ( refer to image 2 ) Try using the same amount of force to move the object in circular motion as with the first object. Do this, while also making sure that stopper ( object 2 ) is being swung in circular motion across a horizontal plane Record the time it takes for the stopper ( object 2 ) to complete 20 revolutions Repeat this five times and record all the observations in the second data table Replace object 2 with the rubber stopper having most mass, this will be object 3.
The construction of the stacked flat laminates is carried out by a mould of rigid and flexible sides. This permits the selection of the mould that processes the laminate very rapidly, accurately and with minimum waste of raw materials. The manufacturing method would produce laminates of greater strength and design flexibility in comparison to the traditional methods such as the hand lay-up. Due to the potential problems that can arise with infusion moulding, a trial and error approach should be used to perfect the setup (Fibre-Glast, 2013). These potential problems are leaks occurring or air getting into the resin inlets, which can create air bubbles or the air could create locks which could lead to resin pooling the part.
There are molecules that are so powerful, they break through the attraction forces that keep the molecules together, this is called intermolecular forces (Ophardt, 2013). Breslyn (2016) explained that boiling point is when vapor pressure of a substance such as liquid is equal to the atmospheric pressure. Atmospheric pressure relates to the space of pressure above the liquid, whereas vapor pressure is defined as pressure that is created by the molecules changing from liquid to gas form, when these molecules change to gas they collide with air molecules. Boiling can take place after or
Friction drilling is a non-traditional hole-making method that utilizes the heat generated from friction between a rotating conical tool and the work-piece to soften and penetrate the work-material and generate a hole in a thin-walled work-piece. It forms a bushing in-situ from the thin-walled work-piece and is a clean, chip-less process. The purpose of the bushing is to increase thickness for the threading and available clamp load. Thermal drilling is a process that uses friction to produce bushing in metal tubing and flat stock. It is a process of combined rotational and downward force, which creates frictional heat that can reach 900 c for the tool and 700 c for the work-piece.
nZVI possesses a large removal capacity, fast kinetics and high reactivity for the degradation/removal of many environmental pollutants (Chen et al., 2012; Chen et al., 2013). It has also been confirmed in previous studies that nZVI has higher absorption and enhanced reactivity for Cr(VI) removal (Zhang et al., 2013) compared to other materials (Montesinos et al., 2014). However, bare nZVI are prone to rapid agglomeration leading to the formation of micro-sized aggregates which lead to loss in reactivity and reduced in the environmental mobility (Grieger et al., 2010). This is attributed to their rapid oxidation, magnetization and high reactivity (Zhang et al., 2013; Zhou et al., 2015). One of the proposed method to overcome this drawback is to coat the nZVI particle surface with surfactants, upon rapid desorption of surfactants into the waste water the particle stability would markedly reduce.
This is to be prevent and avoided at all costs if possible. The good news is that owners can restore the hardwood floor how many times they want. The even much better news is that dust can be prevented and kept to a minimum and possibly eliminated it completely. Because the clear finish on floors has yet to wear through to the nice wood, owners have 2 choices. Find sand hardwood floor, hardwood floor finish repair, wood floor staining, staining hardwood floor, hardwood floor staining, how to sand wood floors, hardwood floor scratch remover floor refinishing without sanding.
(i.e. the level of the permafrost table is raised) – p. 138 The ways that the thermokarst can be decreased include the construction of unheated buildings. This causes the upper surface of permafrost to rise and buildings tilt. Also, large, modern unheated buildings and airstrips are constructed on gravel pads because gravel is less immune to frost heaving and has less tendency to thaw underlying permafrost. Further, human attempts to exploit periglacial regions commercially try to balance short term economic gain and longer term environmental
Bio-foam has a far lower petroleum content than traditional mattress materials. The cutting-edge mattress compression methods used during product packaging make it easy to move the mattress through doorways before unpacking. Making it extremely simple to get the mattress into any room. The Cons Due to the layered design of the mattress, it isn 't able to be used on both sides. Flipping the mattress will result in the uncomfortable support foam being on top.
