this experiment was to obtain some experimental measurement of Vapor Liquid Equilibrium for the Ethanol – Water system to verify the literature data. For this the Ethanol – Water system was heated to a certain temperature which is called the equilibrium temperature at atmospheric pressure and equilibrium temperature and compositions of vapor and liquid were measured. At the equilibrium temperature the samples of both vapor and liquid were taken in two different test-tube and the refractive index of

This chapter discusses the importance of weight management. The most affective way of managing your weight is by controlling the amount of calories that your body consumes with the amount of exercise that you get in your daily activities. Currently about 66% of Americans are overweight. This number has nearly doubled since the year of 1980. There are two types of fats‚ subcutaneous fat‚ visceral fat. Subcutaneous fats are called lipids which affect your nerves‚ brain lungs‚ heart and

The potential of Averrhoa Bilimbi also known as Kamias for it’s fruit as a solution that can be easily be found in the community.The focus of making these dishwashing liquid is on the effectiveness of this plant as an effective antibacterial agent. In the Philippines‚ the leaves of bilimbi tree are used as a treatment relief for skin itches‚ swellings of mumps and rheumatism. It can also be a good alternative remedy

Apparent Weight: Person on Scale in Elevator A person with mass‚ m‚ who is located at or near the surface of the Earth will always have some weight W=mg. When a person stands on a scale‚ the reading (the number of pounds or newtons) on the scale is actually the Normal Force that the scale exerts back towards the person to support the person’s weight. (Note that the person and the scale are stationary relative to each other‚ in other words they are always in contact with each other‚ so they always

If you have ever considered losing weight‚ you have probably heard of the various kinds of diet pills available. Diet pills claim to "melt away the fat." They sound like the perfect solution to shed a few pounds‚ but research tells a different story. Diet pills became popular in 1996. The most common ingredients were Redux and fenfluramin/phentermine‚ which posed as appetite suppressants. The pills seemed to suck up the fat‚ and people were losing anywhere between 25-50 pounds in months. The FDA

Part I: Consequences Part I of The Weight of the Nation discussed the effects of the obesity epidemic in America. It immediately grabbed my attention when they stated that more than 18% of American children are obese. Two-thirds of America (or 68.8%) is overweight or obese. There is a strong connection between a high BMI and diabetes mellitus and hypertension‚ especially when accompanied by a high percentage of abdominal fat. I found it interesting‚ and important‚ that the first woman who shared

The Effect of Molecular Weight on the Rate of Diffusion of Potassium permanganate (KMNO4)‚ Potassium dichromate (K2Cr2O7) and Methylene blue ¹ ABSTRACT The effect of molecular weight on the rate of diffusion was determined using the Agar-water Gel Test. One drop of potassium permanganate (KMNO4)‚ potassium dichromate (K2Cr2O7) and methylene blue were used. Each substance has a respective molecular weight of 158 g/mol‚ 294g/mol and 374 g/mol. The diameters (in millimeter) were measured
