w The Effect of Changing the surface area on the Rate of Reaction? By : 22/10/2013 The effect of changing the surface area on the rate of reaction? Unit Question: Should we speed things up or slow them down? Hypothesis: According to collision theory‚ should the surface area increase the amount of collisions increase increasing the rate of reaction. Therefore‚ my hypothesis is that when the surface area

Chapter II Light and Matter The Inner Workings of the Cosmos 2.4 The Distribution of Radiation All microscopic objects – fires‚ cubes‚ people‚ and stars – emit radiation at all times. They radiate because the microscopic charged particles in them are in constant random motion‚ and whenever charges change their state of motion‚ electromagnetic radiation is emitted. The temperature of an object is a direct measure of the amount of microscopic motion within it. The hotter the object

| | | | | | | | | | | | | Discussion In this experiment‚ the amount of CO2 evolved for different concentrations of Convollaria roots was studied. The question being answered was what kind of effect the increase in concentration of Convollaria roots had on the rate of fermentation. The hypothesis was that the antimicrobial activities in Convallaria majalis’s roots would hinder the process of yeast fermentation because it will cause self- destruction or death in the microorganism

Light pollution Light pollution‚ also known as photo pollution or luminous pollution‚ is excessive artificial light. This phenomenon is pronounced around urban centers‚ where city lights diminish the view of stars and planets. In addition to brightened skies around cities‚ light pollution also refers to any outdoor light that creates glare and interferes with the natural night environment. Cause Light pollution results from outdoor lights aimed

different preventive measures & engaged in joint projects to lower their suicide rates. Countries like China‚ Japan‚ Singapore‚ Australia & Pakistan have joined the project‚ Strategies to Prevent Suicide (STOPS)‚ in order to lessen their increasing number of suicide. However‚ in trying to prevent the increase in number of suicide deaths and attempts‚ one must know what the leading causes of it are. Suicide rates change over time‚ and the factors influencing them remain poorly understood. Economic

The Stroop effect and attention: Effect of automatic and controlled processing on the performance of a colour identification task. Abstract The present experiment aimed to carry out a modification of the experiment on automatic processes carried out by Stroop and to discover whether automatic processing could intrude on a colour identification task. Stoop’s original research found that the response time reading the colour of the ink of the words describing different colour was greater than

Low Interest Rates Long Term Effect "The prolonged low-interest rate environment is transforming the banking industry from savings and loans to service and loans‚" said Dan Geller‚ executive vice president of research firm Market Rates Insight in San Anselmo‚ Calif. (Fitzpatrick) Consumers may think that the continued low interest rates are a profound thing‚ but banks on the other hand think much differently. Consumers are refinancing their houses at rates as low as 2.875%‚ while big banks like
