Aim:To discover what factors affect the rate of diffusion of potassium permanganate crystals in water. Statement:What will happen? How will room temperate solutions or heated solutions increase the rate of diffusion of the potassium crystals?Hypothesis:Heat will speed up the process of diffusion because heat will give out energy that will be able to speed up the process of spreading the potassium molecules.

Simple Diffusion Activity 1: Simulating Simple diffusion 1.What is the molecular weight of Na+? 22.9 2. What is the molecular weight of Cl-? 35.45 3. Which MWCO dialysis membranes allowed both of these ions through? 50‚ 100‚ and 200 4. Which materials diffused from the left beaker to the right beaker? Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin‚ because the molecular weight exceeded the highest MWCO membrane‚ thus being to large to pass through

1. Provide aim and background information 1.1 Diffusion is the process which molecules dissipate into a solution evenly over a period of time. An example is putting sugar in your coffee‚ after a while if you don ’t mix the solution‚ the sucrose will over time‚ go through the process of diffusion and be distributed throughout the coffee. Osmosis is movement of H2O molecules passing through a permeable cell membrane to the less concentrated solution‚ eventually to reach an equivalent number of molecules

Lab # 2 Diffusion & Osmosis Introduction Kinetic energy‚ a root of energy stored in cells‚ causes molecules to hit into each other and move in new directions. Diffusion is the result of this contact. Diffusion is the random movement of molecules to an area of lower concentration from an area of higher concentration. Osmosis is a type of diffusion. This is the diffusion of water through a selectively permeable membrane from a region of higher water potential to a region of lower water

Leadership is a process whereby a person(leader) influences others(followers) to accomplish an objective and intend changes and outcomes which reflects their common purpose(Clark‚2005). Tun Dr. Mahathir bin Mohamad is the fourth prime minister in Malaysia and his reign for 22 years made him the longest serving prime minister in Malaysia which also earned him the longest-serving leaders’ title in Asia. ‚ Mahathir came from a generally modest background unlike his three predecessors known to all

In order to narrow down the focus of my research‚ this paper will briefly discuss what is considered obscene and the different ways in which obscenity will manifest itself. Obscenity law aims at punishment for thoughts provoked or preventing the formation of certain thoughts‚ typically‚ erotic ones in the minds of willing viewers but not for overt acts‚ nor for antisocial conduct. Although the United States Constitution protects the freedom of speech‚ the First Amendment was not intended to

Biology Lab Report - Movement in and out of cells (4A) Shiang Chen Ting (24) Sec 313 Introduction The aim of this experiment is to explore the factors which affect the movement of materials in and out of the cells. The dark red or purple colour of Beetroots is caused by a pigment called betalain that is found within the vacuole of the beetroot cells. The pigment remains intact within the cell if the cells are not “stressed” by the external environment. In this exploration‚ two factors that affect

The purpose of this lab was to observe the rate of osmosis and diffusion‚ as well as the effect of molecular size of the particles on this rate. Part I of the lab was a demonstration of osmosis and diffusion‚ that dealt with raisins in different liquid environments‚ each with a different concentration of sugar. Part IV of the lab was using the same idea as the demonstration‚ by putting objects in different concentrations of a substance; in this case elodea leaves in salt water. In both cases‚ the

Psychopathy is a topic of extreme interest among the psychological community and stimulates wide debate on its various aspects. There have been many studies attempting to define and measure psychopathy (e.g. Levenson‚ Kiehl &ump; Fitzpatrick‚ 1995)‚ but it is commonly thought to be a combination of specific traits and behaviors (Lilienfeld &ump; Arkowitz‚ 2007). Psychopaths commonly have many socially unattractive traits such as callousness and insincerity (Snowden &ump; Gray‚ 2011)‚ however the
