Physics Experimental investigations Will heating honey speed up how it falls from a spoon? The speed of falling of honey from an object depends on its viscosity. Viscosity is a measure of how much a fluid resists movement of a mass through it. It is the internal friction of a substance that causes it to be thick, sticky and adhesive. Apparatus needed for this investigation is: Electronic balance 750 grams of honey (around 530 mL / 530 cm3) Thermometer Bunsen burner / other source of heat /…

This paper will give you a background on freezing point and salt. Like what is freezing point and what does this affects. Also what would happen if you put salt in ice water if there is a effect to the ice and water. This paper will give background about basic chemistry of salt. Also it will give you some background on ice cream. How ice could effect ice cream. Water has the freezing point of 0 degrees Celsius. If you put a ice cube in water the rate of freezing and melting aren't changing. If…

The role of the phenomenon of postmortem redistribution in forensic cases Abstract It has been established in several studies that a postmortem blood sample examination is not always a reliable reflect of blood sample examination during life. There are a large number of variables affecting the blood concentration of foreign substances in a living individual, in the other hand, there are also a number of factors that can change their levels after death. Although the underlying mechanisms involved…

Density of Sand The objective of this lab is to use knowledge from previous labs, like the density of water and solids lab, and apply it to find the density of sand. First you must weigh your graduated cylinder, and record the weight, then pour in whatever amount of sand you choose. You then must weigh that to find the mass, and subtract whatever you got by the mass of the graduated cylinder. After that you pour in some water, and find the difference of how much the water went up and, what the…

Emulsion Independent Research Project A combined effort of Timothy Chase Willard and Marcus Bortey of Mr. Cork’s Second Period chemistry class December sixteenth of 2014  Background Information An emulsion is a mixture of two or more chemicals in liquid form with no mutual solubility. Emulsions are part of two-systems of matter called colloids. Colloids are particles that cannot be seen without the use of a microscope, but are larger than the size of the individual molecules involved in the…

Solids, Liquids, and Gases Solid, Liquids, and Gases are very interesting types of states of matter; however, they are distinct from one another. As already mentioned in class before, matter is everything that takes up space and its right to say that the space that is taken by matter is or a solid or a liquid or a gas. That can prove to us that this three states of matter are essential in this world we know. A solid is a sample of matter that retains its shape and density when…

Frack Off Marissa and Derek Smith and their kids from Pennsylvania cannot live a healthy life any longer. There are ten Hydraulic Fracking wells on their property; one in particular is hundred feet away from their home. From the fracking wells in nearly spitting distance of Marissa’s home, her family is getting sick and they are no longer able to swim, fish or play in the streams near their house. Five generations of their family have lived in the same house and swam, fished and played in the…

Section Two - Oral Liquid Formulations (1) Characteristics of Suspensions: The oral liquid dosage form chosen to formulate was that of a suspension. Given the criteria of Drug Y it was thought best to formulate the drug as a suspension. Suspensions can be defined as ''a class of materials in which one phase, a solid, is dispersed in a second phase, generally a liquid.'' (1) There are many characteristics of suspensions that are relevant when formulating such a dosage form. They are as follows;…

The purpose of this research paper was to determine the influence of cellulose and date palm pad on cooling efficiency, low cost, and reduced temperatures. A study was undertaken to compare the two types of pads to determine the cooling efficiency, low cost, and reduced temperatures. The study found that cellulose pads gave high cooling efficiency, but at the same time increased the total cost. Date palm pads saved water compared to cellulose pads. The cost of using the date palm pad was less…

Facts about Tech Diving You Should Know The conventional limit exceeded by the form of scuba diving specially the recreational diving’s bottom time and depth is known as tech diving. It is also known as Technical Diving. The Technical and Recreational Scuba Diving can be distinguished with lots of differences. According to many people, there are not any obvious differences between Tech and Recreational Diving. They think that ‘diving is diving’ and it is useless to divide it into different types…
