It is not an object‚ and cannot be approached. Rainbow is a full circle of color in the sky caused by water droplets viewed from a certain angle relative to the sun ray ’s. It will be impossible for an observer to see a rainbow from water droplets at any angle other than the

Her art has influenced many around the world‚ including mine‚ the photograph shown in the next paragraph was one of her many pieces that has influenced my own teapot. The artist has not influenced my teapot hugely‚ mainly because I had to put my own ideas into it‚ although her pots

Summary: Our Iceberg is Melting Foreword by Spenser Johnson: One the surface‚ the story of this book appears to be a fable that is relatively easy to grasp‚ but it does subtly impart an invaluable lesson on change. The book covers John Kotter’s Eight Steps to bring about successful organizational change and can be equally useful for a high-school student as it is for a CEO of a multi-national organization. Welcome Note by John Kotter: People do not often understand the need for change. Businesses

solids is done by observing the melting point. This is important because if there is an impure substance the melting point would be depression and the melting range would be broader. By finding the melting point of a known substance one can then observe an unknown substance’s melting point to see if the points are the same and try to figure out the unknown. Experimental Section: The first known substance we used was Biphenyl. 68 degrees Celsius is the known melting point. We used the capillary

Tourism “Honeypots” like Castleton create significant challenges in National Parks. How far does the research you have carried out make you think this statement is correct? My aim is to investigate whether Castleton has been affected by tourism‚ and what challenges Castleton faces as it in the National Park. I will be asking local people but also tourists to volunteer to answer my questionnaire as this would determine but also tell me whether Castleton has been affected by tourism. As below

y to change from the differing states of matter. Due to thermal equilibrium‚ the water would need a set amount of energy to break through the changes in matter. This is why temperature slows down in these phase changes. 2. When the ice is melting is it releasing heat or absorbing heat? Explain your answer. It is absorbing heat as it tries to achieve thermal equilibrium with the incoming heat. The water has more energy‚ which is why the water goes to a more easy to move around “phase” form from

My SRP is determining if the colour of ice affects its melting rate. Ice melts by taking in energy from its surroundings to form heat. This makes the molecules in the ice cube vibrate. As the overall vibration increases‚ the water molecules split from each other turning the ice from a frozen state to a liquid state. Heat can be absorbs in two different ways‚ through direct contact with a hot surface or through radiation of a hot surface nearby. Radiant heat can be contributed by sunlight‚ fires and

The Purity and Purification of Solids- Part 2- Recrystallization Courtney Percival CH 337 Laboratory‚ Section 037 Department of Chemistry Portland State University‚ Portland OR ABSTRACT INTRODUCTION Recrystallization is a commonly used tool in laboratories when dealing with impure solids. "An effective recrystallization is one in which 1) a high degree of purity is achieved as well as 2) a maximum recovery of sample".1 Solubility‚ the tendency of a substance to dissolve in a liquid‚ is an

could measure it melting point. This whole experiment is based on purifying and then finding the melting point of the unknown compound. The theory is that if a substance is pure‚ it will have a very specific melting point‚ within one or two degrees Celsius. This is in opposition to a mixed‚ or contaminated substance‚ which will have a broad melting range. Therefore‚ when we mix our unknown with samples of phenacetin and acetanilide‚ whichever mixture has a more accurate melting point will tell us
