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

Hi‚ my name is water molecule! H2O for short. I live in the bottom of a well. I come from 2 hydrogen atoms‚ but I have an oxygen atom in me! Down here in my well‚ we have a swell time together. In our liquid state‚ we are not too far apart‚ nor too packed together. It’s really great being a liquid! I feel bad for my cousin CO2. He is probably sublimating into a gas from a solid‚ or as a gas‚ freezing back into a solid. He has no melting point‚ only a freezing and boiling point. I’m SO glad I will

Conserving water can greatly limit the negative impact we have on the environment. By thinking conscientiously and creatively‚ we can make sure that everyone has enough water‚ while also minimizing the energy we use to bring it to our faucet or garden hose. Plus‚ using water wisely can lower many water bills. At Urban Times‚ it has been high on our agenda to bring more awareness to the increasing scarcity of water. This infographic‚ brought to us by Seametrics‚ illustrates that our water consumption is

Have you ever dropped oil on your hands and tried to wash it off? What happens? Does the water slide off? Or what about when a drop of oil falls in a glass of water? Why does it float to the surface‚ and not mix? The answer to this is simple: polarity. What exactly is polarity? A polar bond is when there is a difference in electronegativity‚ which means the tendency of an atom to attract a bonding pair of electrons. When two atoms are bonded together and one attracts more electrons‚ this results

One of the World’s great environmental problems - Water The water problem is today one of the greatest problems the world faces. The UN calculates that if the present development continues the 2/3 of the world population will live with serious water scarcity or nearly without water by the year 2025. The UN calculates that one should have 100 litres of water pr day to manage. This is for everything - home consumption‚ agriculture‚ industry‚ etc. Many people today have less than 50 litres‚ and in
