Analysis The trend that my graph and results show is that when the potato was placed in a solution that had a higher concentration than the chip itself‚ the potato lost weight (0.4‚ 0.6‚ 0.8 and 1.0 molars). In the same way when the potato chip was placed in a solution that had a lower concentration than itself‚ the potato chip gained weight (0.0 and 0.2 molars). For my results I calculated the percentage gain/loss in weight using the following formulae: Average change in weight/weight at

about freezing points. This lab was designed to show us the freezing point of a pure solvent‚ in comparison to a solvent in a solution with a non-volatile solute. The second goal of the experiment is to teach students about osmosis. In the experiment‚ we got to observe osmosis as well as understand dialysis. Procecure : Part 1. Colligative Properties 1. Create a water bath by filling ½ of the 100 mL beaker with cool water‚ adding crushed ice to the beaker so the water level is just

Osmosis The purpose of this lab is to study how membranes of plant and animal cells react when exposed to different solutions. The first experiment involves purple onion skin and the second involves rat blood in various solutions. I needed to understand certain terms before preforming this lab to be able to efficiently explain what is happening to the cells. Diffusion is the tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.

How can you use them? You might say that abstract classes are meant to be inherited It contains abstract methods Abstract methods are methods with no definition If abstract methods have no definition‚ how can you use them? ABSTRACT The derived class implements the abstract method’s definition

Abstract Successful electronic commerce sites allow businesses to create low-cost or more efficient channels for product sales or to create new business opportunities. The success and acceptance of most online businesses depend on several factors‚ both technological and social. we examine the role of trust in the successful use and adoption of electronic commerce applications. Trust: belief Based in the system characteristics‚ specifically belief in the competence‚ dependability and security of

weigh less due to osmosis. Our null hypothesis was: If the pH level of a solution is either acidic or basic‚ then it will have no effect on the weight. The independent variable was the different solutions of different pH values. The dependent variable was the weight of the potato‚ which was measured in grams. The baseline of this experiment is the weight of the potato when in the milk solution because milk has a neutral pH. The controls in this experiment are that each sample had

ABSTRACT The penetration of mobile handsets and the increased dependence on it for entertainment and day-to-day activities‚ results into a quest for finding an ideal mobile handset. “Gen Z” is one such project to identify the bundle of attributes that make the best value proposition for the target segment of Student-Youngsters. The segment Student – Youngster is identified on the basis of needs. Now a days‚ there are unimaginable number of features that can come with a mobile handset. However

“Of all the arts‚ abstract painting is the most difficult. It demands that you know how to draw well‚ that you have a heightened sensitivity for composition and for colors‚ and that you be a true poet. This last is essential." -- Wassily Kandinsky. Abstract Art is art that is not a precise demonstration of a form or object. This depiction can be diverged in many ways including the shape‚ color‚ and form. The artist takes the object and then either simplifies it or exaggerates it using these
