DIFFUSION REVIEW WORKSHEET 1. Define diffusion and what causes it to occur? The action of spreading the light from a light source evenly so as to reduce glare and harsh shadows. Diffusion is caused when entities are small and moving in molecules. They collide because they are moving at a random pace. The temperature causes diffusion. 2. Define the terms hypertonic‚ hypotonic‚ and isotonic solution. * Hypertonic: Having increased pressure or tone‚ in particular. * Hypotonic:

everyday life. Diffusion and osmosis are processes that are a constant in our lives‚ even though many don’t realize it. Medicaments such as Fervex can be drunk only after diffusion has taken place and the powder granules have diffused into the hot cup of water. On the other hand‚ every day we become unintentional witnesses of osmosis when the roots of the plants try to suck up the water from the soil (1). The purpose of this lab is to show clearly in an understandable way how diffusion and osmosis happen

changing business world companies from of all sizes have to be aware of the different factors that might affect the way they are managed and ultimately operate. There are two main areas where these factors can originate‚ internally and externally. According to "Businessdictionary.com" (2013)‚ "Internal factors are inner strengths and weaknesses that an organization exhibits. Internal factors can strongly affect how well a company meets its objectives‚ and they might be seen as strengths if they

The kinetics of the Harcourt-Essen Reaction (Hydrogen peroxide variation) Aims: To find the order of the reaction with respect to the Hydrogen Peroxide (H2O2)‚ Potassium Iodide (KI) and the Sulphuric Acid (H2SO4) by the use of an Iodine clock reaction. Calculate the rate constant‚ mechanism and equation Find the effects of temperature on the rate of reaction The effects of a catalyst on the rate of reaction Find the activation enthalpy (Ea) of the reaction‚ with and without a catalyst Background:

Investigating Factors that Affect the Strength of an Electromagnet Aim: To investigate the factors‚ which affect the strength of an electromagnet‚ also known as it’s‚ pick up power. Predictions: The more coils of wire used on the electromagnet then the greater number of paper clips picked up. Also The greater the current the greater the number of paper clips picked up. There will also be a limit to the amount of magnetism created and how many paper clips can be picked up

Another postulate of the kinetic molecular theory is that gas particles are always in motion‚ like the other states of matter. But they are different in that they undergo random translational movement. In solids‚ the particles mainly experience vibrational motion and in liquids they mainly vibrate and rotate‚ with some translational motion. Gas particles move rapidly in straight lines‚ unless acted upon by another particle or the walls of a container. This continuous contact with the container leads

Kinetic energy Potential energy Potential energy is energy stored due to position. The following are some example in which potential energy can be found. 1.

This report’s focus is on analyzing the factors that affect the supply and demand of the products. There are several variables that can affect the supply and demand of a product‚ including consumers’ income‚ prices of substitute products‚ costs of inputs and so on. The product discussed for this report is Acuvue‚ I will analysis how the factors affect the supply and demand of Acuvue. Acuvue is Johnson & Johnson’s Vision Care Product.

Repetition might not help in the second language learning‚ but can surely help to develop the ability of oral communication. Another factor that my classmates and I thought is the most important factor in second language acquisition is motivation. It is logic to say that learners‚ who are motivated‚ will learn more and faster than those who are not. In fact‚ Gardner states that “Motivation involves four aspects‚ a
