Osmosis Experiment Subject: Professor Egg-avier Duration: 3 weeks (Oct 2nd – Oct 16th) Week 1 On October 2nd my group was giving a raw egg (weighing 58.8 grams) and placed it into a clear mason jar with 200mL of vinegar. The ph levels of our vinegar equaled a 2 which tells us that vinegar is a fairly acidic liquid. Once submerged in the vinegar‚ little bubbles began to appear around the egg’s shell. We believed this to be carbon dioxide escaping from the shell. We left our egg to sit in the

Colors of Food Coloring Are Soaked into a Naked Egg‚ Will the Mass Change Depending on the Color of the Ink after 7 Days? The Purpose The purpose of initiating this lab was to test how different chemicals in the outer fluid affects the osmotic properties of a naked egg. Background Information In order to complete this experiment‚ one of the most important things you need to know how to do is how to take the outer “shell” layer off of the egg. The egg shells contain an element known as calcium carbonate

Measuring the Viscosity of Motor Oil ME331 Laboratory Assignment #1 Prepared for: Prof. Sangeorzan Submitted by: Abstract An experiment was conducted to model the effect of temperature on the viscosity of motor oil and compare the results to commercial values established by the Society of Automotive Engineers (SAE) for SAE 30‚ SAE 40 and SAE 5W30. The viscosity of the oil sample at eight temperatures between 20 °C and 55 °C was determined using a rotary Brookfield DV-II+ viscometer

the piece‚ and varying surface area could have a great effect on the rate of osmosis. This is because in an experiment where the potato chip has a large surface area‚ there is a larger area of partially permeable membrane and therefore more opportunity for water particles to pass through. I will keep the surface area the same by keeping the mass and length of the potato piece the same in each instance‚ by measuring and cutting it carefully. I am fairly sure that my results are reliable

AT1- Osmosis In Potatoes Aim: Investigate the movement of osmosis through a selectively permeable membrane‚ in this case potato. Introduction: Osmosis is the movement of water through a semi permeable membrane‚ separating solutions of different concentrations. The water passes from a region of high concentration to a region of low concentration‚ until the two concentrations are equal in concentrations of water. Many cell membranes behave as semi permeable membranes‚ and osmosis is

The Effect of Osmosis on a Potato Cell October 12th 2012 Osmosis Lab Purpose: The purpose of this lab is to investigate the effects of osmosis on a potato cell as it is immersed for a period of time in solutions of different water concentrations. Hypothesis: If the potato is immersed into the distilled water‚ then it will be the heaviest out of the three. This is because water is at the lower is moving toward the area of higher concentration‚ which in this case is the potato. This

3/1/2013 5) In response to the movie "Citizen Kane" one of the reason this film is considered one of the greatest produced is because of the many events in American History it alludes to‚ such as Yellow Journalism. Yellow Journalism was predomintaley seen throughout the 1880’s to the 1900s ‚ it was employed as a business‚ which caused editors to invent many stories that weren’t true. During this time period many newspapers were very intrested in catching the public’s attention rather than promoting

BACKGROUND Egg is considered as one of the most typical food stuff in the country due to its affordability and high nutritive value. Egg’s size is a very important quality parameter for the consumers’ evaluation preferences. Consumers would want eggs with accurate designated size as much as possible. Correct size classification is also useful for the people in a poultry business in terms of sorting‚ packaging planning and in imposing the price for a certain size. The size of the egg is mostly
