Aim: The rate at which a reaction occurs‚ or takes place‚ is affected by various factors‚ such as the temperature at which the experiment is conducted in‚ the pressure which is given‚ the surface area which is exposed‚ use of catalysts‚ and the concentration. In this investigation‚ I would be investigating the affect of surface area‚ or particle size‚ in the rate at which a reaction occurs. Background Information: The more finely divided the solid is‚ the faster the reaction happens. A powdered

heart rate to speed up‚ decrease‚ or stay the same‚ the volume of sound has a high effect on the heart. However‚ if people will let down the volume of sound‚ others would not be mannered by the increase in volume managing to the deadly heart attack. Sound within the community‚ for instance‚ traffic can cause a human’s heart rate of increase. Problem of heartbeat tends to be solved by seeing what kind of sound causes the increase of heart rates to place a termination to increase of heart rate. If

What is the rule of 72? Well… here’s the equation: Years to double = 72 / Interest rate DO NOT reread this equation. The rule of 72 is a hard rule to explain. I will do my best to try to explain it. The answer to ‘rule of 72’ gives us a number of years. This number of years tells us how long it takes to double our money. Let’s say you have 100 dollar. The ‘rule of 72’ helps us figure out how long it will take to have 200 dollars. Scenario 1: You have invested your 100 dollars in a 3%

“Countries grow at different rates because they accumulate capital at different rates.” Is this true? Explain your answer. Since the Industrial Revolution‚ economists have attempted to explain why certain countries economies grow at greater rates than others. The post-Keynesian era saw the introduction of the Harrod-Domar model of economic growth. This model explained an economy’s growth rate by observing the level of saving and productivity of capital in the economy. The neo-classical Solow-Swann

In the interlude and the eleventh chapter of Thomas C. Foster’s How to Read Literature Like a Professor‚ Foster analyzes the different effects violence has in literature.

Change in respiratory rate during exercise Aim: To record and investigate how the breathing rate varies for the duration of light and heavy exercise. Introduction: When an individual exercises‚ the muscles being used needs extra energy from oxygen. The lungs pump oxygen to the heart‚ and then the heart pumps the oxygenated blood through the blood to the particular muscle that is working. The human body has a series of organs working together‚ which is named the respiration system. The organs involved

Professor Chew starts the video off with listing “Beliefs That Make You Stupid” which are beliefs that undermine college students learning. The first belief is that students believe they can learn things and complete assignments faster than they can. The professor says if one wants to truly comprehend the material it takes careful reading and much review. One must plan for assignments to take longer than the allotted time and to always review readings prior to the test. The second belief is that
