Chem 110 09/26/2013 MODULE 5: Caloric Content of Food A) ABSTRACT: This laboratory exercise deals with on how to determine the caloric content of food by creating our own calorimeter. Measuring the energy content of three different food samples by using the change in water temperatures from the heat given off while burning the sample. To verify our results much further — equations‚ such as energy and heat capacity calculations‚ helped us establish on such results. As a result of the experiment

Whitney Miller Chemistry 111-D01L 3/31/2013 Calorie Content of Food Purpose: The purpose of this lab was to measure the energy content of three different food items using the change in water temperatures from the heat of the food. Procedure: 1. With your digital scale determine the empty weight of your 100-mL beaker. 2. Half-fill the beaker with water (approximately 50 ml) and weigh it again. 3. The beaker and water weight minus the empty beaker weight is the net weight of water

requires “burning” food for energy. How much energy is released when food burns in the body? How is the calorie content of food determined? Let’s investigate the calorie content of different snack foods‚ such as popcorn‚ peanuts‚ marshmallows‚ and cheese puffs. Concepts • Combustion reaction • Calorimetry • Nutritional Calorie • Calorie content of foods Background What does it mean to say that we burn food in our bodies? The digestion and metabolism of food converts the chemical
Premium Energy Heat Thermodynamics
Energy content is an important property of food. The energy your body needs for running‚ talking‚ and thinking comes from the food you eat. Energy content is the amount of heat produced by the burning of 1 gram of a substance‚ and is measured in joules per gram (J/g). Usually‚ fat-rich foods like peanuts and cashews provide more energy than just carbohydrates like marshmallows. You can determine the energy content by burning a portion of food and capturing the heat released to a known mass of

Title: Mitosis and Meiosis Abstract: There are two types of nuclear division‚ mitosis and meiosis. Mitosis is usually used for the growth and replacement of somotaic cells‚ while meiosis produces the gametes or spores used in an organism’s reproduction. Hypothesis: Mitosis occurs in whitefish blastula and onion root tip‚ and it is easily observable. Meiosis and crossing over occurs in the production of gametes and spores. Materials: This lab required prepared slides of whitefish blastula

This of course leads to what is commonly called the Freshman fifteen‚ the gaining of at least 15 pounds that first year away from home. With the Fast Food Calorie Counter app it enables the user to input any food from up to 72 different fast food restaurants. This is a great way to stay on top of making sure that student does not over do it and holds themselves
