particles in the form of interactions between the particles. Simply put‚ it is defined as heat transferred by molecules that travel a very short distance before colliding with another molecule and exchanging energy. Theory There are two main studies that the thermal conduction is based on: 1. Linear conduction heat transfer Heat is applied to one end of a bar which results to an elevated temperature at that end and causes the heat to flow towards the cooler end. This will make a gradual increase

Ashley Robins 9/13/11 Honors Chemistry Period 4 Density Lab Purpose: 1. To determine the density of a solid using different laboratory techniques for measuring volume. 2. To use the intensive property of density to identify an unknown substance. Procedure: 1. Obtain a bag marked with a number containing a cube and a cylinder from the teacher. Record the number on the bag in the data table. Density of a cube: Using a balance‚ record the mass of the cube to the nearest tenth of a gram

Flame lab test Chemistry Introduction The lab test performed was to determine characteristic colors that were produced by specific metallic ions that are shown in a flame. This happens when an electron gains energy; the electron moves from an energy level that’s farthest away and to an empty orbital close to the nucleus with higher levels‚ so one of the electrons gives off energy. A flame test is a visual test where the energy is in the form of a color change and the change can

Lab Report Abstract: The purpose of this lab was to see how magnesium reacts with oxygen. This reaction must be forced with heat. As magnesium changes to magnesium oxide the mass increased. Procedure: 1. Set up the stand and bunsen burne. 2. Go to crucible heat oven to obtain a crucible. 3. Weigh the crucible and lids mass. 4. Break up the magnesium ribbon on the crucible and weigh the mass of the magnesium‚ crucible‚ and lid. 5. Place the crucible on the ring stand over the flame. Allow

department Data security – Lab # 1 Lab Description Set-UID is an important security mechanism in Unix operating systems. When a Set-UID program is run‚ it assumes the owner’s privileges. For example‚ if the program’s owner is root‚ then when anyone runs this program‚ the program gains the root’s privileges during its execution. Set-UID allows us to do many interesting things‚ but unfortunately‚ it is also the culprit of many bad things. Therefore‚ the objective of this lab is two-fold: • Appreciate
