and Diffusion Lab Report Background Information: Diffusion involves the movement of solute particles across a selectively permeable membrane from higher to lower concentrations. A selectively permeable membrane allows only some thing to go through. Water and oxygen are examples of molecules that are able to go through the membrane by diffusion. The

The Energy of the Future The United States of America is in desperate need of an alternate energy source. One such alternate source is nuclear power. Nuclear power is a form of energy produced by an atomic reaction‚ which is capable of producing an alternative source of electrical power‚ replacing the energy currently supplied by coal‚ gas‚ or oil. This will help the United States move away from burning fossil fuels and potentially reduce overall pollution. Nuclear power has the potential to be

Wind energy • Energy from wind power is becoming an increasingly significant source of energy • (considering that the price of oil is getting dearer) 1. this specially so for oil deficient developing nations like India which meet their energy needs by importing oil. 2. providing fact and figures analyze the opportunities and challenges that wind energy companies face in setting up wind farms in India. ▪ Also do u think wind energy is viable if the government decide

Activity One: 1. The two major variables that affect the rate of diffusion: a. The composition of the lipid bilayer (eg. more cholesterol‚ less permeability to polar substances) b. The structure of the molecule undergoing diffusion (eg. steric conformation‚ size‚ polarity‚ amount and strength of hydrogen bonding) 2. Urea was not able to diffuse through the 20 MWCO because the pores of the membrane were too small for the urea to pass through. The molecular weight of urea is 60.06 g/mol‚ over

Anjali Patel Riley Egan‚ Nick Morrison 10/2/13 Block 2 LAB REPORT OUTLINE FOR DIFFUSION/OSMOSIS LAB Introduction: Diffusion is the net movement of small or uncharged molecules or substances from areas of higher concentration to areas of lower concentration. There is simple diffusion‚ as explained‚ and facilitated diffusion. Facilitated diffusion‚ on the other hand‚ involves larger or charged molecules or substances that need a protein tunnel through the membrane to help the substance enter and

Not better… but I’m getting there. The key factors that affect my mental health would definitely be my lack or sleep and the amount of things I currently have on my plate. I know this is something that won’t change until graduation‚ so honestly I am tired of dwelling on it. I am literally 2 days away from finally being FREE! I will say though college has been an uncomfortable growth experience. I saw someone state that in their write-ups on blackboard and I instantly connected. I want to see myself

Potential Energy Potential Energy is a type of energy that does not involve motion. It is the energy that is stored up. The more work done to change an object’s position or shape‚ the more potential energy it has. For example‚ a person on a ladder has more potential energy than a person on the ground because they have done more work to get up there. Kinetic Energy Kinetic Energy is the energy of motion. The more work an object has done‚ the more kinetic energy it has. the amount of kinetic energy

Calculating Efficiency. Efficiency (%) = Useful Energy Out x 100 Total Energy In Questions 1) A light bulb takes in 30J of energy per second. It transfers 3J as useful light energy and 27J as heat energy. Calculate the efficiency. 2) A kettle takes in 2000J of energy per second. It transfers 1500J as useful heat energy and 500J is wasted as sound energy. Calculate the efficiency of the kettle. Remember: In the exam they may not
