There is a beaker with 0.4% sucrose solution and the solute potential is -4. Inside the beaker, there is a dialysis bag with 01% sucrose solution, solute potential -1 and pressure potential 0. When the beaker is open to the atmosphere, what is the pressure potential of the system?
Since I have no idea how to help you with this subject, here's a lesson in "how to search on the Internet:"
At this webpage, you can go immediately to the search sites (first three columns across the top) -- or even better you can scroll down until you see the section called HOW TO SEARCH THE INTERNET. Those are the links to start with. You'll not only learn how to come up with good search terms, but also how to evaluate the webpages you get as results. Some will be good and others will be garbage. You need to know how to tell the difference.
My favorite way to search is to go to Google's advanced search page http://www.google.com/advanced_search?hl=en and put my search words or phrases into the first or second search box (either "all the words" or "exact phrase"). However, there many other strategies for searching you can use, and the HOW TO SEARCH THE INTERNET section will help you best.
Learning to use Google or other search engines can save you time and help you learn to find information efficiently. Here are some websites that can teach you how:
... and one to help you judge whether a particular website's information is worth your time:
Happy searching. Thanks to Writeacher.
well, since water potential is pressure + solute concentration, that means that it would be the sum of the beaker AND the dialysis tubing. so. -4 + -1 is -5. Should be the answer. :P
