  • Used Temperature Scale In The World
    734 words
    Hot and Cold Winter is coming to the northern hemisphere, and with it, talk of central heating, gloves and scarves, snowfall, and record low temperatures. Monitoring temperatures is part of our everyday life - whether we " re talking about the weather, our bodies, central heating, or cooking. In the United States, we typically measure temperature in degrees Fahrenheit. But in other countries, such as England, you " ll get the weather forecast in degrees Celsius. Recipes will advise you to bake a...

    I. Introduction A. Purpose: the purpose of this experiment was to determine if the distance between matter effects the time it takes for the matter to reach thermal equilibrium. B. Hypothesis: If the distance between the matter is decreased then the time it takes for the matter to reach thermal equilibrium will decrease. C. Science concepts: Temperature- measure of the motion of molecules Thermal equilibrium- when two pieces of matter are the same temperature Kinetic energy- energy of motion Hea...
  • Water In The Brew Pot
    1,088 words
    Introduction There are thousands of different styles of beer in the world today but the one thing they all have in common is that the brewing process has been the same for 4,500 years (Papazian, 2003). The steps are basic: clean the equipment, make the wort, ferment, and bottle. There are many books on brewing beer and they are exhaustive with theory. This being the case, the fermentation process, and the bottling will not be cover herein. By following these simple instructions, anyone can make ...
  • 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...

  • Movie's Ice Age
    1,054 words
    The movie, The Day After Tomorrow, addresses the issue of global warming. The movie's portrayal of the events caused by global warming was extreme and not very believable. Some of the information is backed up by science but most is completely off the wall and non realistic. The movie cited the cause of the global climate change to be the rise in temperature due to greenhouse gasses. The warmer temperatures caused the polar ice caps to melt, and the increased amount of freshwater in the ocean dis...
  • Air Water Temperature Experiment
    2,638 words
    INTRODUCTION - Since its introduction to the New Jersey shore in 1988, the western Pacific shore crab Hemigrapsus sanguineus has spread to inhabit rocky intertidal locations along the Atlantic coast from Massachusetts to North Carolina (McDermott 1998). Many reasons have been proposed to explain the rapid spread of this non-indiginous species. For example, it has been shown that H. sanguineus has longer spawning periods along the mid-Atlantic coast than it does in its natural habitat in the west...
  • 20 00 Ml Hydrogen Peroxide Room Temperature
    1,385 words
    Aim: To investigate the effect of temperature on the enzyme catalase. Prediction: Using my existing scientific knowledge, I predict that as I raise the temperature to 30, 35, and 40, this is where we will see the greatest reaction. I predict this because enzymes are designed to react best at the body temperatures of the animals to which they belong. For a mammal, this is around 35-36. Catalysts are used to speed up biochemical reactions in the body. An enzyme is a protein molecule that speeds up...
  • 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...
  • Room Temperature Water
    838 words
    Using Charles Law To Determine Absolute Zero Tuesday 7th of December Introduction: One of the variables that affects the volume of a gas is the temperature of the gas and its surroundings. This volume-temperature relationship is quantified in Charles law. The law states that as the temperature of a gas decreases, the volume of the gas decreases proportionately. An ideal gas at 273 K, for example would decrease in volume by 1/273 of its original volume for each Celsius degree the temperature decr...
  • Chloride Water 100 Ml Of 1 M
    870 words
    Blank 1 Blank ity BlankBlankity Blank Mr. Blank 4/9/02 Effects of Salts on the Freezing Point of Water In this experiment, you will study the effect that several solutes have on the Freezing Point of water. When a solute is dissolved in a liquid, the temperature at which that liquid freezes decreases, because the molecules of the solute become attached to the water molecules, making it more difficult for the water to form its crystalline shape and form into ice. This process is called Freezing P...

Variables"X Water"X Teaspoons"X Time"X Ammonium Nitrate"X Thermometer"X Stirring (used thermometer) ...
  • Glasses With Water Of Three Different Temperatures
    599 words
    In this research we are going to give the narrative of a scientific experiment in order to get some insights on how the scientists do their job. We are going to conduct one scientific experiment in order to have the idea of the experimental science in the way it is done by the masters of the subject. For our experiment we take: a clear (transparent) drinking glass; a room thermometer (usually measures degrees from less than 0 degrees F to more than 100 degrees F); glasses with water of three dif...
  • Exposed Surface Area Of A Huddled Animal
    380 words
    Aim: The aim of this experiment is to investigate how groups of animals conserve heat in cold climates. Hypothesis: I hypothesis e that a huddled group will lose less heat than an isolated animal. This is because the exposed surface area of a group of animals is less for each animal than an isolated animal (as shown below). S. area of 1: 10 + 10 + 10 + 10 = 40 cm S. area of 4: 40 x 4 = 160 cm However... S. area of 4 huddled: 20 + 20 + 20 + 20 = 80 As you can see the surface area doesnt increase ...

    Purpose: Try to have a chemical reaction between Alka seltzer and water be controlled so that the lid of the canister pops of in exactly 15 sec. Hypothesis: If a 1/4 of a solid Alka-Seltzer tablet and 15 mL of hot water is added then the lid of the film canister will pop off in exactly 15 seconds. Introduction: vs. Temperature- causes atoms to move faster vs. Surface area- more space to react in vs. Concentration- an amount of substance used to react with another substance. vs. Catalyst- a subst...
  • 36 0 C 14 2 Test Tubes
    3,905 words
    Introduction: Enzymes are biological catalysts that regulate and accelerate the rate of biochemical reactions within a cell, but are not used up or changed in those reactions, therefore are accessible for reuse. They allow reactions to occur at a lower temperature than would otherwise be necessary in their absence. However, almost every significant life process is dependent on enzyme activity and without them life would cease. Enzyme activity occurs on chemical substances known as a substrate. E...
  • Water Temperature Of The Water
    800 words
    What is thermal pollution? One of the most serious ways that humans change the temperature of waters is through thermal pollution. The raising of the air or water temperature by artificial means is called thermal pollution. Thermally polluted water often undergoes biological changes that make it less valuable for drinking, recreational, habitat and industrial uses. What causes Thermal pollution? o Industries, such as nuclear power plants, may cause thermal pollution by discharging water used to ...

  • Camel's Body Temperature
    1,517 words
    Adaptions In Ectothermic And Endothermic Animals To Adaptions In Ectothermic And Endothermic Animals To Extreme Climate Adaptions in Ectothermic and Endothermic animals to extreme climates First of all we need to understand what ectothermic and endothermic animals are. Animals differ in their abilities to regulate body temperature (thermoregulation). We sometimes use the terms "cold-blooded' or "warm-blooded. ' Most reptiles feel cold to the touch, while mammals and birds often feel warm. Somewh...
