www.igcse.at.ua ORGANIC CHEMISTRY OIL and its many useful PRODUCTS The origin of oil Crude oil is formed from organic material of the remains of plant and animal organisms that lived millions of years ago. These remains form sediments eg at the bottom of seas‚ and become buried under layers of sedimentary rock. They decay‚ without air (oxygen)‚ under the action of heat and pressure to form crude oil over millions of years. It is a fossil fuel because it is formed from

RESEARCH PLAN Materials and Methods To make a good quality of cream‚ the necessary materials needed in making cream will be gathered by the researchers. The research will collect 375 ml of kamote leaves extract‚ 600 ml of vegetable oil‚ 175 grams of paraffin wax. Research Design The research will employ the Static-Group Comparison Design. Static Group Comparison Design – two already existing‚ or intact‚ groups will be used. These are sometimes referred to as static groups (Franenkel and Wallen 2005:272)

now made to utilize common things in order to make products easier and cheaper. In this research study‚ used cooking oil is used as an alternative for paraffin wax in candle making. In the field of science‚ this study contributes a lot for the reason that we can find alternative for paraffin wax as main component in candle making; besides paraffin was derived from petroleum and the latter is much expensive. This study contributes knowledge to the researchers and also to the community in the sense

in the candle. Results of the tests showed that the candle made from 100 percent paraffin wax had the lowest melting rate‚ lowest amount of melted candle. The 90:10 preparation had the next lowest melting rate and amount of melted candle. The other preparations ranked according to the proportion of used cooking oil in the candle‚ with the 50:50 preparation performing least comparably with the 100 percent paraffin wax candle.

In this lab‚ I calculated the heat of combustion of paraffin (candle wax) by burning a candle and holding a calorimeter (a soda can) filled with 98.7 mL of water above the flame. The heat released by the candle was absorbed by the water in the can. It was important to place the metal chimney around the candle so that minimal amounts of heat would escape; having too much heat lost to the atmosphere would cause extra error in the calculations. The assumption made was that all heat released from the

The Tuba-tuba Plant (Jatropha curcas) Also known as Tubang Bakod in Tagalog‚ Physic Nut in English or interchangeably tuba-tuba orJatropha. The latest craze to hit the agri-business in the Philippines. Cultivated primarily for its oil to produce biodiesel. The Tuba-tuba has been planted in the Philippines for quite some time but it was used mainly as fencing since it animals do not eat the leaves -even the insatiable goat would not eat the leaves. The ever increasing price of petroleum prices has
