    Good hydration is important for athletes as their body lose water through sweat to keep it cool down. Control levels of fluid and water balance even before‚ during and after training or during matches are essential aspects for the athletes. For low intensity exercise lasting for a short duration such as low intensity training or during rest between each training session‚ water is very good for rehydration (Nutrition Australia‚ 2009). In addition‚ high intensity and endurance sports last longer than

    CULINARY CALCULATIONS The Standardized Recipe The standardized recipe is the hallmark of the foodservice industry today. The information contained in the standardized recipe ensures that a consistent product is always served to the guest. A consistent product means the look‚ taste‚ texture‚ and portion size of the menu item is the same each time the item is prepared and served‚ regardless of who is in the kitchen on a given day. Each standardized recipe has a specific yield‚ which can be increased

    • 4 Pages

    Enthalpy‚ represented by the sign ∆H in kJ/mol‚ is the heat change in a reaction. It shows whether how much heat is released or absorbed during the reaction. If the reaction is endothermic‚ the enthalpy would be positive and if the reaction is exothermic‚ the enthalpy would be negative. During a chemical reaction‚ which consists of breaking and creating bonds‚ heat is either absorbed or released. In this lab‚ the reaction uses the disassociation of an ionic compound ammonium nitrate shown in the

    Measuring the Enthalpy change of combustion Abstract This simple experiment is carried out to show the difference in the enthalpy change of combustion between two fuels‚ hexane and methanol. These fuels are individually weighed before and after used as heat source to heat water in a calorimeter. The result is used to find out amount of heat transferred by the fuel‚ amount of fuel used and the enthalpy change of combustion. Introduction Enthalpy change of combustion is the enthalpy change when

    Calorimetry: Enthalpy of Neutralization Introduction: The purpose of this lab experiment was to determine the molar concentration of the unknown HCl by using a coffee cup calorimeter. A coffee cup calorimeter is made of Styrofoam cups with a thermometer that is placed from the top and into the calorimeter to measure the temperature as the reaction happens. The Styrofoam cup used for the calorimeter creates an isolated system as it acts as a heat insulator between the cup and the surrounding
