Title : The Physical Properties of Water Aim : 1. To comprehend and learn about the factors that affects the boiling rate and the boiling point of water. 2. To evaluate the moisture content of foods. 3. To observe the relationship of different relative humidities of the surroundings towards the sensory properties of foods. Results Table 1: Part a(i) – Heating 200ml of Water Time (s) | Temperature (⁰C) | 0 | 23 | 30 | 24 | 60 | 27 | 90 | 30.5 | 120 | 35 | 150 | 37.5 |

FATS AND OIL DEFINITION: Fats and oils‚ group of organic substances that form an important part of the diet and also are useful in many industries. The fats are usually solid‚ the oils generally liquid at ordinary room temperatures. Some tropical products‚ liquids in their sites of origin‚ become solids in cooler climates; in commerce these often retain the name originally given‚ e.g.‚ palm oil and coconut oil. Chemically fats and oils are either simple or mixed glyceryl esters of organic acids

Fats and oils - 344 Iodine value of an edible oil INTRODUCTION Fats and oils known as triglycerides contain long chain hydrocarbons with carboxyl groups (COOH groups). These fatty acids are classified into the number of double bonds present in the fatty acid. When the carbon atoms in these chains are bounded to the maximum possible number of hydrogen atoms‚ the triglyceride is said to be saturated. When one or more double bonds exist between carbon atoms in the chain‚ less hydrogen exists

When fat is stored in the body‚ while were losing weight‚ the fat gets burned off. First‚ in activity 1.1‚ the lab data about jogging shows there was an -6 difference in calories before then after exercising. Also‚ on page 11‚ it states‚ “You know that when you go from sitting to running‚ you increase the amount of energy your body needs. This increase in amount of activity causes the changes you observed when you exercised in class.” This evidence means to me that‚ when we work out‚ we burn the

Measurement in Fats and Oils. Introduction : Vegetable oil is an important and widely used lipid source for our everyday food products. Its application is increasing day by day for food purposes and for the manufacturing of a number of toiletry products. However‚ some vegetable oils are not up to standards to meet consumer satisfaction in terms of their physico-chemical properties or for the texture and stability of the food products (Reyes- Hernandez et al.‚ 2007). Recently‚ palm oil has become

Banana Oil Lab Report Jesse Bradford 7/10/14 MTWR Section Introduction In the banana oil lab we began with isopentyl alcohol + acetic acid isopentyl acetate + Water. We needed for this experiment a hot plate‚ clamps‚ pipette‚ 5mL vial‚ caps‚ hoses and a thermometer. Upon starting‚ our group set up an open system experiment that allowed gases to be released to avoid pressure build up. We mixed together to molecules‚ 1.0mL of isopentyl alcohol‚ 1.5mL of acetic acid

our obsession with low-fat foods. We’re bombarded with supposedly guilt-free options: baked potato chips‚ fat-free ice cream‚ low-fat candies‚ cookies‚ and cakes. But while our low-fat options have exploded‚ so have obesity rates. Clearly‚ low-fat foods and diets haven’t delivered on their trim‚ healthy promises. Despite what you may have been told‚ fat isn’t always the bad guy in the waistline wars. Bad fats‚ such as trans fats‚ are guilty of the unhealthy things all fats have been blamed for—weight

For this lab‚ 40.2 mL of canola oil were used as the initial volume for the production of synthesized biodiesel. Through the synthesis process‚ 31.307 grams of canola biodiesel was produced‚ which is a percentage yield of 85.714%. In order to get this percentage yield‚ the following calculations were made: 40.2 mL canola oil × 0.9073 g1 mL=36.5 g × 1 mol376.6 g=0.0416 moles canola oil From the prelab‚ for every 1 mole of oil‚ 3 moles of biodiesel are produced. 0.0416 mol oil × 3 mol biodiesel1

Oil Spill Clean-up: Lab Report Description There are various methods for cleaning up oil spills. Some methods allow oil to be recovered‚ whereas others do not. Some methods are more expensive than others‚ some are more efficient than others‚ and some have more of an environmental impact. Regardless of the method used‚ cleaning up oil spilled on water is a very time-consuming and difficult task. In this activity‚ you will model various methods used for cleaning up an oil spill on water. Material
