On the aspect of repeatability, Walker reported that whilst most of his results were repeatable, he sometimes observe large variations in his results and said “I have not been able to resolve the controversy”. Having boiled some milk for making ice cream, his class were told to let the mixture cool before putting it in the refrigerator. Mpemba, however was anxious of ensuring himself a space so put his mixture in straight away. I said Mpemba re-discovered this; having mentioned this “Mpemba Effect” in one of their articles, the “New Scientist” was subsequently flooded with anecdotes from all over the world of only the hot water pipes freezing during a short cold snap, ice-rink operators preferring to use hot water and so on. Osborn and Mpemba published these results in a journal called “Physics Education”, coincidentally the same year that George Kell at the National Research Council of Canada in Ottawa reported the same phenomenon that year in the “American Journal of Physics”. In a subsequent year at high school Mpemba was taught about Newton’s law of cooling in science: the rate at which a body cools is proportional to the temperature difference between that body and its surroundings:…which leads to the solution… Any set of cooling curves plotted from such a function will never cross, no matter what the initial starting temperature. So a curve which starts at a higher temperature will never undercut a curve starting at a lower temperature and will therefore always take longer to cool. Varying the parameter k on the other hand could well cause graphs to cross. But this parameter is determined from some initial conditions, if both systems are not identical in such things as geometry or arrangement, with the exception of starting temperature, then it is hardly appropriate to compare cooling times for different initial temperatures. The lab-assistant reported the hot water had frozen first, but not to worry, “I’ll keep on repeating the experiment until we get the right result.” After several attempts it seemed Mpemba was right – hot water would freeze faster than cold water. However, Mpemba was undeterred by a theory which didn’t seem to support his observations: he’d asked a friend who sold ice cream in a nearby town who told him he routinely used hot mixtures because they froze more quickly. Still persisting with this, in 1969 a visiting academic from University College in the capital called Dr Osborne came to visit Mpemba’s school and he jumped at the opportunity to quiz him about this apparent violation of Newton’s Law. Thankfully he didn’t dismiss it outright, and upon returning to Dar es Salaam, he instructed a lab-assistant to carry out an experiment to see if hot water would freeze more quickly than cold water. Publish or perish He came away with the simple observation that “hot liquids freeze faster than cold liquids”.His science teacher told him this was impossible and he must have got mixed up. So why exactly is this impossible? So this clearly wasn’t unheard of. Mpemba was a secondary school student in Tanzania in 1963 who had the fortune of re-discovering some interesting physics during one of his cookery lessons. Surely the validity of this effect can be deduced by carrying out experiments – however this has proved surprisingly difficult. The Mpemba effect is only observed under certain conditions – there are clearly many factors which could affect how quickly water cools such as the geometry of the container, the volume of water and the temperature of the refrigerator. In 1977, Jearl Walker published results in the “Scientific American” whereby the time to freeze was measured against the initial temperature for a variety of containers. His results showed two things. Firstly where negative gradients occur, water at an initially higher temperature appeared to be freezing more quickly. Secondly, this is by no means a universal effect, since most of the curves showed very little (if any) in the way of negative gradients. The other students waited and put their mixtures in later, after they’d cooled down. Having noted the time his ice cream entered the freezer compared with the rest of his class, Mpemba realised his mixture had frozen significantly faster than everyone else’s. So assuming both Newton and Mpemba are correct – how do we understand what is going on here? Can we somehow reconcile these two arguments? CHECK BACK NEXT WEEK TO FIND OUT…by Will Frass
Georgia 4-H will be adding 16 new positions in some of the state’s most impoverished counties because of a grant from the Georgia Commission for Service and Volunteerism.Georgia 4-H received one of the highly competitive 2012-2013 AmeriCorps State & National Grants from state commission and the Corporation for National and Community Service.The 16 new, direct-service employees will work in Appling, Banks, Bibb, Clayton, Coffee, Crisp, Dougherty, Decatur, Hart, Heard, Laurens, Putnam, Troup, Tift, Union and Washington counties. They will assist University of Georgia Cooperative Extension agents in delivering youth programs. “With the reduction in state and federal funding for Extension 4-H programs, we have to look for other ways to supplement funding for county 4-H programs across the state,” said Georgia 4-H State Leader Arch Smith. “These Americorps workers provided through grant funding will help county Extension 4-H offices reach more young people and give more children the positive educational youth development opportunities offered by Georgia 4-H.”AmeriCorps grants advance the priorities of the bipartisan 2009 Edward M. Kennedy Serve America Act and focus on six key service areas: disaster services, economic opportunity, education, environmental stewardship, healthy futures, and veterans and military families.”Our board had very difficult funding decisions to make this year because the requests for AmeriCorps grants far exceeded our available funds,” said GCSV Executive Director John Turner. The commission, which administers AmeriCorps and other federal grants to service agencies in Georgia, received applications requesting more than $6 million from 24 applicants. AmeriCorps had $3,980,239 available for grants.The commission renewed the grants for 12 existing AmeriCorps programs for 2012-2013 year, including: Clayton State University, Communities in Schools, Fannin County Family Connection, Georgia Perimeter College, Georgia State University, Georgia Tech, Goodwill of Southern Rivers, Hands On Atlanta, Jumpstart Georgia , Refuge Resettlement Services and Immigration Services of Atlanta, United Way of Metro Atlanta and Youth Villages Inner Harbour Campus.For more information on Georgia 4-H’s AmeriCorps grant, contact Jeff Buckley at [email protected] or (706) 542-8735.
