Part A: Title: Diffusion Diffusion is the spontaneous movement of particles from where they are more concentrated to where they are less concentrated. For this experiment‚ a 14 cm glass was filled with cold tap water. A drop of red food coloring was dropped in the cup. A stopwatch was used to measure the time it took for the food coloring to get to the bottom of the cup. The average diffusion rate was .78 cm a second. If a different color was used‚ I do not think it would have made a difference

It’s all about a Break and the Power of Healing What is a Wound? A wound may be described in many ways; by its aetiology‚ anatomical location‚ by whether it is acute or chronic1‚ by the method of closure‚ by its presenting symptoms or indeed by the appearance of the predominant tissue types in the wound bed. All definitions serve a critical purpose in the assessment and appropriate management of the wound through to symptom resolution or‚ if viable‚ healing. A wound by true definition is a breakdown

A simple rule to remember is: salt sucks Salt is a solute‚ when it is concentrated inside or outside the cell‚ it will draw the water in its direction. This is also why you get thirsty after eating something salty. Type of Solutions ISOTONIC SOLUTIONS If the concentration of solute (salt) is equal on both sides‚ the water will move back in forth but it won’t have any result on the overall amount of water on either side. HYPOTONIC SOLUTIONS The word "HYPO" means less‚ in this

OSMOSIS ASSESSMENT TASK Introduction Osmosis is the net movement of water particles from an area where they are in high concentration to an area of low concentration‚ down a concentration gradient. Hypothesis: Will a high concentration of salt solution affect the mass of a potato chip? Variables Controlled variables: -The sizes of the potato chips. Bigger size of potato chips will weigh heavier and the smaller potato chips will weigh lighter‚ if we don’t use the same size of potato chips

Problem question: When a Shell - less egg is placed into a beaker of corn syrup‚ will there be any water going into or out of the egg and if the shell - less egg is placed in a beaker of distilled water will be any net flow of water going into or out of the egg. Hypothesis: If a shell - less egg is placed into a beaker of corn syrup solution‚ then there will be a net flow of water going into the egg because the water molecules will be small enough to pass through the membrane of the egg.
