affected by thermal energy? My answer to that question is when thermal energy is added to the substance‚ the particles have increased on energy and move around more‚ but when thermal energy is decreased‚ particles are closer together‚ so they don’t move as much because they are low in energy as well as space. Temperature: The question being asked to answer is if temperature is affected by thermal energy. My answer to that question is its affected because when you add thermal energy the temperature

Entity-Relationship Diagrams (ERD) Data models are tools used in analysis to describe the data requirements and assumptions in the system from a top-down perspective. They also set the stage for the design of databases later on in the SDLC. There are three basic elements in ER models: Entities are the "things" about which we seek information. Attributes are the data we collect about the entities. Relationships provide the structure needed to draw information from multiple entities. Generally

The syllabic structure in English Outline 1. Theories on syllable formal ion and division. 2. The structure and functions of syllables in English 1. Theories on syllable formation and division Speech can be broken into minimal pronounceable units into which sounds show a tendency to cluster or group. These smallest phonetic groups arc generally given the name of syllables. Being the smallest pronounceable units‚ syllables form morphemes‚ words and phrases. Each

Martin Luther King Jr once wisely said: “ The time is always right to do what is right “. He faced challenges because of his skin color and the time period he was in. True heroes exist today because people face challenges. The first reason why heroes exist today is that people are brave. Bravery is when someone goes towards danger and aren’t scared. Melissa Hawkinson that bravery by saving a young boy’s life. The article from Reader’s Digest says “ she tugged on the window until it opened and then

Energy Drinks: Stuff that Kills When most people comsume an energy drink‚ they don’t realize that the short burst of energy that it gives them can also kill them. Energy drinks are an easy way for people to get the energy that they need in 5-10 minutes. If they are feeling sluggish‚ then they can just grab a can of an energy drink. Energy drink can be found almost anywhere: in the gas station‚ at the store‚ and even in some schools. Most schools are banning energy drinks they still

PLANNING Investigating the Kinetics of the reaction between Iodide ions and Peroxodisulphate (VI) ions By the use of an Iodine clock reaction I hope to obtain the length of time taken for Iodine ions (in potassium iodide) to react fully with Peroxodisulphate ions (in potassium Peroxodisulphate). I will do three sets of experiments changing first the concentration of iodide ions‚ then the concentration of Peroxodisulphate ions and finally the temperature of the solution in which the reaction is
