Identification of Unknown Organic Compounds by Melting Point‚ Boiling Point‚ and Infrared Spectroscopy Methods and Background The goal of this laboratory experiment was to determine the structure and identity of an unknown solid and an unknown liquid by using elemental analysis‚ index of hydrogen deficiency‚ infrared spectroscopy‚ melting point (for solid)‚ and boiling point (for liquid). In this laboratory‚ we were given unknown solid “C” and unknown liquid “D”. The empirical formula

Conduction Conduction Conduction is the transfer of thermal energy between regions of matter due to a temperature gradient. In the engineering sciences‚ heat transfer includes the processes of thermal radiation‚ convection‚ and sometimes mass transfer and often more than one of these processes occurs in a given situation.Shaun Prado 8F Shaun Prado 8F Steady-state conduction Steady state conduction is the form of conduction.

pollution. Earth’s atmosphere contains mostly water vapor‚ carbon dioxide‚ and methane (natural greenhouse gases) which act to keep the lower layers of the atmosphere warmer than they otherwise would be without those gases. Greenhouse gases trap infrared radiation. The radiant heat energy that the Earth naturally emits to outer space in response to solar heating. Mankind’s burning of fossil fuels releases carbon dioxide into the atmosphere and this is believed to be enhancing the Earth’s natural

shape of the crystals will differ for each specific drug. 5. What is spectrophotometry? How can this useful in identifying drugs? A spectrophotometry device can emit both UV and infrared light as it measures how a sample either reflects or absorbs. Though ultraviolet spectrophotometry cannot identify a drug‚ infrared spectrophotometry can‚ since the pattern of light is unique to each type of compound. 6. Why are forensic scientists an important part of drugs cases? forensic scientists can use

CHAPTER 1 INTRODUCTION The rapid development in science and technology has paved its way for sophistication by automation. People now a days‚ are inclined towards devices that are sophisticated‚ simpler to use and secure. In this project entitled “Home Appliances Control using Different Controlling Modes “‚ a prototype is developed which shows how the best utilization of technology can be made in order to secure a home not only from threat but also by ensuring all the safety measures.

ACKNOWLEDGEMENTS It is usually said that no man is an island unto himself‚ and any man who so lives all by himself‚ without interacting with his fellow men is in the words of Aristotle‚ “either a beast or a god”. Mutual co-operation and interaction form the cardinal feature of human life. The task of writing this report has not‚ in the least‚ been an easy one‚ and it would be axiomatic to add that all the numerous tasks involved could not be have been accomplished successfully singly
