  • Types Of Iguanas And Types Of Environments
    343 words
    This report is on how the environment affects iguanas and their color. I will also include types of iguanas and types of environments. There are several types of iguanas; such as the marine iguana, green iguana and rhinoceros iguana; but I am mostly focusing on green iguanas. ' One consideration of an iguanas color is diet. The iguana should get a daily salad of lettuce, chard, and parsley, carrot, sweet potato, cucumbers, grapes, melon, peppers, and rose petals. Its diet should also consist of ...
  • Newspaper Round A Beaker With Hot Water
    729 words
    Physics Investigation How does insulation effect the loss of heat In this investigation I am going to try and find out what difference it makes if you wrap newspaper round a beaker with hot water in it and see if the heat loss is different at different thickness layers of newspaper. I carried out a preliminary experiment and found out that by only increasing the layers of thickness by 1 each time, that wont make enough difference to make a good graph because the trends will be too similar. So I ...
  • Temperature Of The Water
    1,170 words
    Procedures: The purpose of this lab was to determine the specific heat of two different metals. In order to do this, specific directions were executed in order to discover the specific heat. First, we needed to obtain and record the weight of the Styrofoam calorimeter cup. Next, we filled the cup 2/3 full with cool tap water and recorded the temperature of the water. After this was done, we filled a glass beaker half full with water and placed it on a hot plate in order to have the water reach b...
  • Greatest Amount Of The Sun's Heat
    556 words
    Solar Energy This experiment deals with the testing of solar energy and what material holds the greatest amount of heat. Solar energy is heat that the sun gives off. The materials used to determine what holds the heat the longest are rock, soil, water, and stone. The purpose of this project is to see what of the four materials hold the heat the longest. My hypothesis is that soil holds the heat or energy the longest is because soil is black. Black is the number one heat tracker. The procedures I...
  • Percentage Of Water In Copper Sulfate Pentahydrate
    1,082 words
    Percent Composition Of Water In Copper SUlfate Pentahydrate (Lab Report Version) Abstract The percentage of water in Copper Sulfate Pentahydrate was found. Copper Sulfate was heated in a crucible to evaporate the water. The mass was weighed to find the difference before and after heating. By comparing these masses, the percentage of water was found. The percentage of water was found to be 34%. Theory Copper Sulfate Pentahydrate or Cu SO + 5 H O is a solid compound. To find the percentage of wate...
  • Convection And Radiation Heat Transfer
    378 words
    Conduction, Convection, and Radiation Heat transfer is the way heat moves through matter to change the temperature of other objects. There are three types of heat transfers, Conduction, Convection, and Radiation. The first kind of heat transfer, conduction, is heat transferring through direct contact of materials. This would be the same thing as a pan on the stove. The heat from the stove touches the pan directly, therefore making the pan hot. The next type of heat transfer is convection. Convec...
  • One Hundred Sixty Thousand Calories
    469 words
    People are, by nature, very gullible, nieve and border on ignorance. There are very few that strive for understanding. Most accept what is told them by friends, the media and the government without question. Take for, instance, the calorie. Millions of Americans read the labels of food containers and worry endlessly about the number of calories that a food contains. This is a classic example of human ignorance. How can one worry about something and not know what it is, where it comes from, and w...
  • 500 Cm 3 Flask The Rate
    2,136 words
    Biology Coursework Practical - Heat Loss The aim of this practical is to find to what extent does the surface area to volume ratio of an object affect the rate of heat loss from the object Hypothesis: As the ratio of surface area to volume of an object decreases the rate of heat loss from the object will also decrease. Objects with the same surface area to volume ratios loose heat at the same rate so long as there are not other variables involved. Background Knowledge: The surface area to volume...
  • Two Insulators The Rate Of Heat Loss
    2,100 words
    Science Investigation: Insulation Introduction My investigation is to find out the rate of which heat transfer happens. Heat transfer is a process in which energy in the form of heat energy is exchanged between materials that are at a different temperature. Heat is generally transferred by conduction, convection, radiation and evaporation. All of these processes can all happen simultaneously but it is likely that one will give the greater heat exchange. Heat is exchanged through the brick wall b...
  • Differences In The Amount Of Heat
    2,281 words
    Investigating The Combustion Of Alcohols - Planning This investigation involves burning alcohol in the air. Key science- Chemistry by Eileen Ramsden says that ' an alcohol is a series of organic, homologous compounds, with the general formula Cn H 2 n+1 OH'. The alcohol reacts with the oxygen in the air to form the products water and carbon dioxide: Cn H 2 n+1 OH + (n+n/2) -1 O 2? nH 2 O + nCO 2 The structure of the molecules in this reaction isO- H + 3 [O = O]? 1/2 [O = C = O] + 3 [H-O-H] | | H...
  • Water Molecules
    439 words
    What properties of water make it a unique material and an essential component of living matter Water is so common that it is easy to overlook the fact that it is an exceptional substance with many amazing qualities. With its properties, we can trace water's unique behavior to the structure and interactions of its molecules. Water is constructed of two hydrogen (H) and one oxygen (O). The hydrogen become + charged and the oxygen maintains a charge when they combine to form water. This is a single...
  • Heats Of Reaction For Salts In Water
    3,336 words
    Introduction A team was sent to the chemical manufacturing division of a small chemical company to help the technicians with experiments. Since the notes written by the technicians were inaccurate and unfinished, all of the experiments they had preformed needed to redone and documented correctly. The head of the company gave the new team the task of trying to figure out why some chemical reactions caused the reaction vessel to get cold and others caused the vessel to get hot. The group construct...
  • Viscosity Of A Non Newtonian Fluid
    407 words
    Most fluids used in the chemical, pharmaceutical, food, and biomedical industries can be classified as non-Newtonian, ie, the viscosity varies with shear rate at a given temperature. In contrast, Newtonian fluids such as water, air, and glycerin have constant viscosities at a given temperature. Examples of non-Newtonian fluids include molten polymer, aqueous polymer solutions, scurries, coal-water mixture, tomato ketchup, soup, mayonnaise, purees, suspension of small particles, blood, etc. Becau...
  • Loss Of Heat From One Surface
    756 words
    Hypothesis Larger animals lose heat at a lower rate than smaller animals. As the organism gets bigger the volume and surface area ratio decreases. This means that there is less surface area to lose heat from. If we use penguins as an example, the larger penguins live closer to the poles that the smaller penguins. So smaller animals have a higher surface area to volume ration and larger animals are the opposite. As the size of the animal increases the rate f heat loss decreases. The rate of heat ...
  • Percent Of Water In A Hydrate
    718 words
    Abstract: When salts are crystallized from water, they take up a fixed amount of water as part of their crystal structure. The water that is retained by the salts is just enough to give the geometry and the bonding needed of a crystal. The quantity of water that is retained is called water of hydration or water of crystallization. The crystal formed is called a hydrate. A hydrate, usually found in nature, is a chemical compound made of an exact amount of water and another substance. Water of hyd...
