Osmosis and Water Potential Year 11 Emary Venter INTRODUCTION: The cell is the basic unit of living things‚ and is made up of multiple organelles. Organelles are membrane bound subdivisions‚ each specialised for a specific function. This experiment looks at the Plasma Membrane‚ which is a semipermeable layer surrounding the cell. It’s primary job is to control what goes in and out of the cell. Molecules can move across this membrane in either an active movement or a passive movement

Every human being has their own unique system of how they carry themselves through the day. These systems are how we survive‚ and they tend to become part of our subconscious. But there are those who get so caught up in their own conformity that daily life becomes much more demanding than it should be. The results of this perpetual routine can

685N and your belongings have a weight of 915N. How much work does the elevator do in lifting you and your belongings 5 stories (15.2m)? Solution: W= (685N+915N) (15.2m) W= (1600N) (15.2m) W= 24‚320Nm or J Section 2 Gravitational Potential Energy: 6. A 0.15kg ball is thrown 9.0m straight up. What is the work done by the gravitational force? And what is the change in PE? (Notice anything?) Solution: PE= m*a*h PE= (0.15kg) (9.8 m/s^2) (9.0) PE= 13.23 kg m^2/s^2 or J - The

Abstract: Water potential is the measure of free energy of water in a solution. The purpose of this lab was to find the water potential of a potato cell. The problem of this lab was‚ if there was a high molarity of solute‚ would it have a positive or negative water potential? The hypothesis of the experiment was‚ if there is a high molarity of solute then the water potential would be lower or negative. After obtaining potatoes‚ we cut them into pieces‚ weighed them‚ and then placed them in a solution

oxidation-reduction reactions. The first part of the experiment measures the standard electrode potentials of five various half cells against the Cu2+(1M)|Cu half cell. The last three half cells are prepared through electrolysis. The electrode potentials of all reactions are positive which means that they are spontaneous. There is a significant percent difference from the theoretical and the experimental standard electrode potentials. The sources of error are incorrect solution preparation and contaminated materials

marble the potential energy to hit the target cup. Energy is the ability to do work. Potential energy is the energy of position and kinetic energy is the energy of motion. In order for the ramp to be successful‚ the ramp had to have the right amount of potential and kinetic energy. If you have too much potential energy than the marble would have too much kinetic energy and the marble would not land inside of the target cup‚ it will go right over the top of it. If you have too little potential energy
