Effect of osmosis rate on different surface areas‚ depending on different types of water solution An investigation showing the effect of surface area on osmosis rate‚ including some different types of water concentration. Osmosis is a type of passive (not requiring energy) transport of water molecules across partially permeable membrane‚ from an area of high water concentration into area of low water concentration. But how does surface area affect rate of osmosis? Surface area plays important

Chemical Kinetics Factors Affecting Reaction Rate OVERVIEW Chemical reactions occur at different rates. In this experiment you will consider some of the key factors that influence the rate of a reaction: nature of reactants - particle size temperature concentration catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the faster the rate of the reaction. However‚ in order for the

CHAPTER 4 (MANKIW) INFLATION RATES AND INTEREST RATES: THE FISHER EQUATION NOTES by: Chadia Mathurin Economists differentiate between real and nominal interest rates where: real interest: is defined as the increase or decrease in a consumer’s purchasing power experienced as a result of changes in the interest rate. nominal interest: is defined as the interest payed by the bank. Let: i denote the nominal interest rate r the real interest rate pi ‚ the inflation rate The equation for the

The purpose of this practical is to investigate how the pulse rate of humans changes when they exercise. Someone who is physically fit can supply their muscles with enough blood‚ carrying glucose and oxygen‚ for an activity at a lower heart and breathing rate. The fitter you are the lower your resting heart rate. You and your classmates will be the humans investigated. SAFETY: If you know you have any condition that affects you doing exercise‚ please make sure your teacher knows before you start

common methods known as the direct method and step-down method. The direct method is used “ to allocate costs from the general services departments to each patient service department in one step” (Smith‚ 2014). The direct method calls for financial accounting to document the immediate movable expenses that is in each cost pot and to choose a cost controller for the indirect pot (Smith‚ 2014). The step-down method is almost like the direct method‚ the only difference is that it has three interceding
