Experiment: At this experiment we are investigating does the temperature affect how quickly the particles diffuse to an even concentration throughout the water‚ we are going to do this experiment by using food coloring to see how quick the food coloring diffuse in hot water and cold water. Materials: • • • • • • • • One beaker Hot plate Ice Water Food coloring Thermometer Timer Eye dropper Hypothesis:I think the food coloring will spread faster‚ because the particle in the hot water have more

Introduction: Diffusion and osmosis are passive processes of transport. Passive transport involves no disbursement of energy by the cell. Diffusion movement is from high concentration to low concentration‚ which the driving force for this type of movement is kinetic energy particles themselves. Which crystal (Methylene blue‚ solid or Potassium Permanganate KMnO4-purple) will move further than the other due to the driving force (kinetic energy)? My prediction is that Potassium Permanganate KMnO4-
Premium Diffusion Molecular diffusion Osmosis
Diffusion is the molecular net movement from a higher concentration to a lower concentration. For instance‚ when a person is smoking‚ the smoke diffuses into the air. The molecules in the smoke‚ released from the cigarette‚ travel through the air. Here is how it occurs. When molecules are close enough‚ they collide with each other‚ their kinetic energy changes. Due to the direct relationship between diffusion and molecular kinetic energy‚ the molecules move away from the point of the collision as

Title: Diffusion throughout the membranes Lab Partner(s): Alexis Clouting Date: 2/15/15 Abstract: In the content of the Module 2 we learned about Diffusion across cell membranes. We touched on the different types of cells and their functions. How things are transported in and out of cells. Learning about isotonic‚ hypertonic and even hypotonic solution. This is not my first time touching on this subject in my nursing career and I learned a way to remember what happens in the different solutions

Emily K 20 August 2013 Diffusion Lab Research Question: How does the amount of water in a beaker affect the rate at which food coloring diffuses to the bottom of the beaker? Independent Variable: Height of water in beaker (Inches) Dependent Variable: Rate of diffusion (seconds) Controlled Variables: * Size of beaker * Temperature of water (23°C) * Type/color of food coloring * Person Timing * Environmental conditions Materials: * Beaker(well over 4 in tall) * Food

Zaballero Group 10‚ 2D Medical Technology‚ Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT Distillation is the most common technique‚ it is a process wherein the liquid is separated from the solution by boiling the liquid solution and condensing the vapor in order to get the distillate. There are four kind of distillation: simple distillation

Brian Toohey Biology Mrs. Heimforth 12/06/10 Diffuse the Osmosis Section 2: Introduction Step 1: The scientific concept of this lab was to see how osmosis transferred the substance through the cells to reach equilibrium. Step 2: My hypothesis was that the bag with 60% sucrose then it would be heavier than the bag with tap water or 30% sucrose. I thought this because I thought that there would be more of a substance change in 60% sucrose. Section 3: Methods First get 3 pieces of the same
Premium Experiment Diffusion Weight
Diffusion is the process by which a particular phenomenon --- such as a contagious disease‚ a technological innovation or even an idea --- is spread from person to person over a period of space and time. One method of diffusion is known as expansion diffusion‚ which is broken down into three distinct types. Expansion Diffusion * Strictly defined‚ expansion diffusion is the process of spreading something from one place to another in an ever-expanding "snowballing" process. Expansion diffusion
