build-up of fats. Statement of the Problem How to purify and reuse cooking oil for further usage? Objectives of the Study This investigatory project determines the possibility of purifying used cooking oil using sedimentation method. The activated carbon was also used in the experiment to absorb some dissolved substances in the oil. There were three different setups used in this study namely; Setup 1 (sedimentation was done once); Setup 2 (sedimentation was done twice); and Setup 3 (sedimentation

you learned about the natural environment‚ how it is impacted by humans‚ and how that impact is measured. Now‚ you’ll apply what you learned. 1. In Section 1‚ there were several examples of systems‚ such as a car engine‚ the water cycle‚ or the carbon cycle. Think of a system you’re familiar with‚ and then answer the following questions. a. What system did you choose? (1 sentence. 2.0 points) water cycle b. What are the inputs of the system? (1 sentence. 2.0 points) evaporation c.

The carcinogenic nature of N-nitrosamines depends on the organs. For example‚ their targets for cancer in rodents include thyroid‚ pancreas‚ urinary bladder‚ trachea‚ lung‚ oral and nasal cavities‚ esophagus‚ kidney and liver. With respect to N-nitrosamides‚ skin‚ bone‚ peripheral nervous system‚ brain‚ small intestine and glandular stomach are targeted organs for cancers. Besides cancer‚ acute myelocytic leukemia and T and B cell lymphoma have also been triggered by N-nitrosamides. In table 8.1

What is the environmental and social impact of using coal to produce electricity? According to the Energy Information Administration (EIA)‚ burning fossil fuels accounted for approximately 67% of the total amount of electricity produced in the United States in 2015. Coal and natural gas lead all electricity production at 33% each and the other 1% came from petroleum. The way that coal produces electricity is through a process of energy transformations which are completed in coal power plants.

Answer: Plastic was thought to be a boon but it turned out to be a curse. Plastic can be very harmful as it produces harmful gases when it is burned. As it is non bio degradable‚ it is harmful to the soil and takes hundreds of years to degrade or decompose. Plastic is a boon for man but it is a curse for the master. It makes life comfortable for man but life tiring for the environment. Once animals have eaten it and due to choking they die Plastic is very harmful to living things. We

PHB consists of a long carbon chain‚ indicating it has a rather strong dispersion force because of high molecular weight. Hence it has a considerably high boiling and melting point. Its tensile strength is also close to that of polypropylene‚ allowing it to be made into reusable
