amount of solute affect the time it takes for the solute to dissolve?” I thought about this question for a very long time and come up with a hypothesis for the investigation was “If the amount of solute increases‚ then the time for the solute to dissolve will increase. This is because the solute will become more concentrated and it won’t disolve into the solvent as fast. (Sadner‚ 2008)” Looking at the data I collected‚ I think that this hypothesis was accepted‚ because the more solute added‚ the

Diffusion and Osmosis in an egg Low concentration 1.1 Diffusion is the process of molecules spreading from areas of high concentration to areas of low concentration. High concentration 1.1 Osmosis is the diffusion of water molecules through a semi-permeable membrane from the area of low concentration of solute to the area of high concentration of solute. 1.2 Diffusion is important to living cells because it’s the way they take in materials from the environment‚ and they also prevent themselves

* Diffusion-is the process whereby particles of liquids‚ gases‚ or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration. The rate of diffusion depends on the size of the surface area to the volume in the cell. The higher the surface area of cells in relation to their volume‚ the quicker diffusion takes place. Experiment on Diffusion Aim: to determine diffusion Materials:

Diffusion And Osmosis Abstract In this Diffusion and Osmosis lab a total of three experiments were performed. For experiment 5.1 we investigate diffusion through a selectively permeable membrane and the many factors that influence the rates of diffusion. In experiment 5.2 we investigate both animal and plant cells in different molar solutions and the different osmotic behaviors within the cells. In experiment 5.3 we test the osmolarity of plant cells through the usage of potato tuber cells

CHAPTER ONE 1.1 INTRODUCTION Economic growth is fundamental for sustainable development. It is not possible‚ for a developing country‚ to ameliorate the quality of life of its growing population without economic growth. The relationship between government expenditure and economic growth has continued to generate series of debate among scholars. Government performs two functions- protection (and security) and provisions of certain public goods (Abdullah‚ 2000) and (Al-Yousif‚ 2000). Protection

investigation was to observe if certain solutes would result in dissolving in different solvents. Solubility is what determines if a substance will dissolve in a certain solvent. The ionic solutes will dissolve into the polar solvents and the covalent solutes will dissolve into the non-polar solvents because the molecules of the solvents have a stronger force that will break apart the solute and dissolve it into the solvent. Procedure Small amount of the solutes‚ roughly one scoop from the scoopula

1. Explain the relationship between the skeletal and muscular systems. The relationship between the skeletal and muscular systems is that we are made up of bones all throughout our body and we need this to stand and hold our body together‚ similar to the skeletal system the muscular system is made up of soft tissue and is lined all over our body. We could not stand without the system as well. 2. Why is the circulatory system important? This system is important because it is used to circulate blood
