as ys 5 6 One day, a college professor named Denis Osborne came to lecture on physics, giving Mpemba an opportunity to talk to an expert on the subject. He repeated his question, but this time he got a quite different reaction. The professor first smiled and asked, “Is it true? Have you done it?" After Mpemba la horruitnos ewenibaa admon M answered "Yes," the professor said, "I do not know, but I promise to try this experiment when I am back at my college." 7 Professor Osborne kept his word and carried out the experiment himself. He found that for temperatures up to 20°C, the time was roughly proportional to the temperature above freezing, up to a maximum of 100 minutes at 20°C. For higher temperatures, however, the time dropped dramatically, down to 40 15 minutes for water at 80°C. le 10► 700

Humans depend be careful to use them wisely. on natural resources in many ways, so we must brow ent Resources can be divided into two categories: renewable and non-renewable. The difference is that renewable resources recover naturally over time. Renewable resources are usually living things like animals or plants. For example, trees are a renewable resource because they can be grown again after we cut them down. But oil is a non-renewable resource because it takes millions of years to form again. We must try to conserve non-renewable resources because once they are used up, we cannot get more. Natural resources can be traded between countries. They can create a lot of wealth for resource-rich countries. For example, Saudi Arabia, Iran, and Kuwait in the Middle East have large amounts of petroleum. They export it to other countries and make a lot of money. ssl 10 ayaw inshoami ni olqueq siroteirting en A arbelbeforq alaihe erit @ 'eviso ant qu baisvos adoOR O eves ortt birt aloon eeuse 0 ni molte notni Jedno nisam chi apnang VOLUME vert befotong ant extoon nettet no obiani op bludo sho no bhoo boop ni perle. petroleum enew donitisq eviso eni to YOGI oil found under the surface of the earth or under the sea daiq Q BACK 05 Sentence Simplificat
