  • Determing the Enthalpy of Neutralization

    2507 Words  | 11 Pages

    enthalpy of neutralization reactions by calorimetry. Calorimetry, is the science of measuring the amount of heat. All calorimetric techniques are therefore based on the measurement of heat that may be generated (exothermic process) or consumed (endothermic process). The device used for measuring the heat changes in this experiment is called calorimeter. A calorimeter is a Styrofoam cup is used as a calorimeter, because it is a container with good insulated walls to prevent heat exchange with the environment

  • Metabolism : A Machine Fueled By Activity And Temp

    1287 Words  | 6 Pages

    Metabolism: A Machine Fueled by Activity and Temp. Introduction What is metabolism? Metabolism is all of the chemical reactions involved in maintaining the living state of the cells and the organism. The Major point of this experiment was to see how and if the chemical processes of metabolism could impact body temperature. However first it must be explained what body temperature is actually measuring. When we measure body temp. We are actually measuring the body’s ability to make and give off heat

  • Compare And Contrast Ammonium Nitrate And Calcium Chloride

    1592 Words  | 7 Pages

    they contain calcium chloride. Therefore, when a hot pack is needed the pad is squeezed and the water and the calcium chloride mix, which creates the hot pack. There are new concepts that relate to this lab, such as exothermic and endothermic reactions. Endothermic reactions

  • Exothersmic And Endothermic Interaction

    765 Words  | 4 Pages

    Research In our daily life, we constantly have interactions of chemical reactions, such as endothermic and exothermic reactions. In general all chemical reactions are important to our society to achieve certain activities. Some examples are smelting iron,making class, burning fuels,brewing beer, making wine and cheese, and etc. Most importantly I will be researching what are exothermic and endothermic reactions and how they can affect our daily life. Chemical reactions is a process when the

  • Essay on Ice Packs an Endothermic Reaction

    1042 Words  | 5 Pages

    * . Introduction Endothermic reactions are accompanied by the absorption of heat. The dissolving of ammonium nitrate in water is an example of an endothermic reaction. The solution resulting from this mixture is colder than either the ammonium nitrate or the water. This is the simple explanation of what happens in an instant ice pack. The more detailed information will be discussed in the following paragraphs. Cold Packs Most cold packs come with a fabric cover made to absorb condensation and

  • Adaptions in Ectothermic and Endothermic Animals to Extreme Climates

    1123 Words  | 5 Pages

    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. Somewhat more precise descriptions can be made by using the terms poikilothermic and homoiothermic. The body temperature

  • Endothtermic And Exothermic Reaction Lab Report

    775 Words  | 4 Pages

    reactions that release energy are called exothermic reactions, these reactions are observed by an increase in temperature of the reaction mixture. Chemical reactions that absorb energy are called endothermic reactions, these reactions are observed by a decrease in temperature of the reaction mixture. Endothermic and Exothermic reactions release or absorb energy, the graph above shows the way in which the chemical energy changes. In this experiment, we investigate the change in temperature caused by

  • Exothermic Lab

    427 Words  | 2 Pages

    We already knew that exothermic means to exit or release heat energy. Endothermic means to absorb heat energy. Chemical reactions are when one thing changes into another but it cannot return to it’s original form. We read about instant hot packs and cold packs and how they are chemical reactions. When water mixes with different salt or some substances it can cause a decrease or increase in temperature. In our experiment our guiding question was which of the following substances would make an economical
