oxidized and thus causes reduction ELECTROCHEMISTRY INVOLVES TWO MAIN TYPES OF PROCESSES: A. Galvanic (voltaic) cells – which are spontaneous chemical reactions (battery) B. Electrolytic cells – which are non-spontaneous and require external e− source (DC power source) C. BOTH of these fit into the category entitled Electrochemical cells GALVANIC CELLS Parts of the voltaic or galvanic cell: o Anode--the electrode where oxidation occurs. After a period of time‚ the anode may appear to become smaller

particles either consist of particles that are either hot or cold. High temperature bodies‚ are often caused due to the high heat transfer‚ which is created by chemical reactions‚ nuclear reactions‚ electromagnetic dissipation‚ or mechanical dissipation. Heat is generally transferred between two different objects by radiation‚ conduction and convection. Heat is only passed on between objects‚ with the help of different temperatures.

Chapter 15 & 16: Temperature‚ Heat & Heat Transfer Temperature is a measure of the average (not total) translational kinetic energy. ●ex: there is 2x as much total molecular kinetic energy in a 2L of boiling water than one‚ but the temp of the two volumes are the same (average of translational kinetic energy per molecule is the same in each → Internal Energy- the total of all molecular energies: kinetic+potential (SAME TEMP) ● Ex: apply a flame to 1L h2o for a certain time and its temp rises

How to Tell if a Cell Phone Is Being MonitoredHow to Tell if a Cell Phone Is Being Monitored With all of the latest hullabaloo about cell phones being used as bugging devices‚ you may be feeling a bit creeped out at the prospect of being monitored without your knowing it. Although some cell phones can be remotely programmed‚ most modern cell phones would require physical access to your phone to tamper with it. Luckily‚ when cell phones are transmitting‚ certain tell-tale signs can be a dead giveaway

------------------------------------------------- Cell phones Imagine being able to talk to someone that is across the world with a push of a button. Seems a little far-fetched? Well‚ there is such a device that allows you to do that. It is called the cell phone. Cell phones are devices that enable people to talk to others no matter how far away they are from each other. They can be on opposite sides of the planet and they still will be able to talk to each other. Many people nowadays use cell phones very frequently for

Cell Reproduction Eric Gonzalez Strayer University Week 4 Lab Professor Lynn Roginsky 22 Jul 11 Cell Reproduction The goal of this week’s lab is to explore the effects cancerous cells can have on tissue in the lungs‚ stomach‚ and ovaries. Using a microscope and slideshow and based on readings in the lab the following are answers to questions asked in the experiment. Based on the data gathered from observation differences in normal cells and cancerous ones have revealed themselves. Most

Effect of varying Temperatures on Enzymatic Activity of Bacterial and Fungal Amylase and hydrolysis of Starch Abstract This experiment consisted of setting up a control group of starch in various temperature and then placing both fungal amylases and bacterial amylases in a mixture of starch and placing the solution of amylase and starch in various temperatures of water. After a certain amount of time- different amount of time needs to be used in order to have reliable results- iodine is added

Continental Temperature Ranges Introduction: There are large variations in average monthly temperatures among cities located at the same latitude. This suggests that factors besides the angle and duration of isolation affect the rate heating and cooling of any given location. Objective: You will graph the average monthly temperatures of costal and inland continental regions and interpret the range in temperatures. Vocabulary: Temperature range- Average daily temperature Average monthly

Cell phones are changing social interaction Having a cell phone is a really good thing to have for emergencies or any other type of situation you’re in. using your phone is fine but using it a lot does affect the way you see the world‚ once you do let go of that phone you should notice things more. Many teens and very few adults use phones a lot but mostly the young adults use it more often. Cell phones creates us humans to struggle in particular occasions because we don’t pay attention
