surface area vs rate of time
In the investigation an experiment is conducted investigate if the breaking of alka seltzer into ½, ¼ and none effect the time it dissolves. The context of the problem is the time it dissolves to have the medicine show its effect. This problem exist in real life as people take alka seltzer to relief heartburn, acid digestion and stomach aches. This experiment would benefit society because it informs the society the better way of consuming medicine or alka seltzer in order to see faster effect in the body.
Aim: To investigate the breaking of the alka seltzer into larger surface area (½ and ¼) affects the time it dissolves.
Hypothesis: The more alka seltzer is broken, it dissolves faster in water and the less it’s broken, slower it dissolves in water.
- 9 alka seltzer
- Room temperature water
- 3 Glass cup or clear plastic cup
- Measuring cup
Safety risks and precautions:
Spilling water on electrical appliances, getting a cut with a knife or broken glass
Make sure to proceed this experiment on a table far away from electricity or any electrical appliances.
Be careful when cutting or breaking the alka seltzers.
Be careful not to knock over the…
At first, as I was examining the image of the swimmer, I thought about determining the area between the swimmer’s legs. At first, I thought that I could relate it to the area of a triangle, but later acquired the fact that the side length and height of an isosceles triangle cannot be equivalent, which meant that the area of a triangle would not fit this image.

In Figure 2, I have attempted to display an isosceles triangle to put in place of the swimmer's…
Demonstration of the Relationship between the Surface Area to Volume ratio on the rate of Diffusion
The surface area to volume ratio determines the rate of diffusion, the larger it is the faster nutrients will diffuse. Phenolphthalein acts as an acid-base indicator, turning pink in bases like NaOH and being colorless in acids like HCl. Using agar blocks as cells, a model was made to measure the rate of diffusion of different sized pink agar blocks changing to colorless ones.…
DIVERSITY AND SIZE
Effect of Surface Area on the number of species in biodiversity.
Yes, there is a relationship between species diversity and size, the smaller the habitat the less diversity of species there will be.
Species diversity is the variety of organisms that make up a community
It has two components:
• SPECIES RICHNESS: is the total number of different species in the area
• RELATIVE ABANDANCE: is the proportion each species represents in that certain measured area. we recognize…
concentration of a solution, presence of a catalyst, surface area, pressure of gases, temperature etc. These reaction rates may have positive or negative effects in our everyday lives. Today, I will be talking about how temperature, surface area and concentration can have a role in our everyday life.
Firstly, a factor that affects the rate of a reaction that we see every day is temperature. We see temperature affecting rate of reactions through making food. For example, bread dough rises more…
Characterization of ZnO and ZnO/CR nanoparticles
The average pore size and total pore volume of ZnO/CR were determined at 77.4K by nitrogen adsorption isotherm using Micromerities ASAP2010.was used to calculate the specific surface areas of The value of specific surface area of ZnO and ZnO/CR samples determined from the method Brunauer–Emmett–Teller (BET). Scanning electron microscopy/Energy-dispersive X-ray spectroscopy employed to analyze the size, morphology and structures of the ZnO and…
Communal Areas Cleaning London
Do you own a large commercial property, student property, flat share or office block? If you do, then you will have to address cleaning communal areas. The reason is because you must provide residents or visitors to such property with healthy living conditions that stand up to certain standards. You could try and take on such task on your own, but odds are it will be too large a job. By outsourcing the job to a communal areas cleaning company, you can take the…
simply by breaking these readings into smaller portions and not allowing myself to become overwhelmed with the 75 pages that are required to be read and discussed.
Organization is a must for me and by having a planner with all my assignments listed has helped me tremendously by allowing me to stay abreast of what is currently expected as well as aware of future assignments. Devoting time to actually absorb what I have learned is important to me, as well as staying current with what chapters I…
Euclid states, “a surface is that which has length and breadth only”(22). The term surface is one that is controversial in science today. Due to theories such as string theory, the idea of infinite dimensions is a possibility in modern science. Euclid does not define surface with the possibility of numerous dimensions therefore his specific belief of a surface can be questioned. Because a reader in the modern era is able to use current science to possibly question Euclid, again the reader can…
Table 3 shows the BET surface area of both the fresh and hydrothermally aged SCR catalysts. For fresh BEA zeolite and SCR catalysts, as the doping amount of catalytic additive increases, the BET surface area decreases, probably because the additive Cu, Ce, and Nb species blocked some of the zeolite channel, hindering the entry of N2 into the pores (Bin et al. 2014). After aging at 600 °C, all the samples showed 3-20 m2/g increased BET surface area. Aging condition of 600 °C is a relatively mild…
