lowers the market value to ensure proper popping‚ the density also plays a part in the popping that should occur. Purpose: To perform the quality control tests and competitive analysis in the popcorn industry‚ and see if the kernels meet industry standards. Part A: Measurement of Density Procedures: Weigh 10 kernels of unpopped popcorn. Find the volume of those kernels using water displacement in a 10-ml graduated cylinder. Calculate density of sample(D=M/V). Repeat 3 times using new a new

January 2011 Math Anxiety: Fertilizer Calculations Y OU MAY KNOW people who suffer from math anxiety. They avoid situations where mathematics and calculations are required. However‚ avoiding math is simply not an option when working with agriculture. The International Plant Nutrition Institute (IPNI)... in cooperation with university specialists...has recently published a “how-to” workbook that presents commonly used mathematical concepts in agriculture. It begins with simple arithmetic

30‚ 2012 1. Title: Laboratory Techniques and Measurements 2. Purpose: The purpose of this lab is to learn laboratory techniques and to how to measure precisely. During this lab I will learn how to measure length‚ temperatures‚ volume‚ density‚ and mass using laboratory equipment. I will be using laboratory equipment to prepare dilutions and calculate them while using an algebraic formula. 3. Procedure: In order to perform this lab I needed the following materials: a metric ruler

temperature by subtracting the initial temperature of the aluminum from the final temperature of the aluminum. ΔT = Tf - Ti (5 points) Determine the mass of the water by using the water’s density (specific to the initial temperature) and the volume of the water. Remember‚ density = mass/volume. You can look up the density of the water at your specific temperature. (5 points) Use the equation: q = m(SH)ΔT to solve for the amount of heat gained by the water from metal. You have the mass of water from

Purpose : To demonstrate the principle of buoyancy of warm air. Additional information : The density variation between warm and cool air can be used to explain why warm air possesses higher buoyancy. As hot air contain atoms and molecules with higher kinetic energy than cold air‚ it has a lower density and rises up while the colder air goes downwards. In other words‚ cool air ‘sinks down’ displacing the warm air. Required materials : Balloon
