The ways to keep your coffee hot

This article provides such information that how to contend with a cup of coffee. The writer did some experiments to cool his coffee. The purpose of these experiments was to probe which method was the best to cool the coffee. Subsequently, cup 1 had a cover on the top, cup 2 had not lid and the third cup had a lid, yet he would blow on the opening. After several minutes, in consequence the cup without a lid was cooler than other, even though he poured the water with a little different temperature before. It was perfectly plain that by putting coffee next to something colder thermal energy was transferred to another colder coffee. However, this experiment was not enough to prove the theory. The second experiment was by evaporation. It was clear that when the coffee evaporates, by and large, the coffee cup without the lid with the result that it instantly became cooler than before. Afterwards, he took one more experiment with plugging in the small hole and lid and another one just had a lid. Surprisingly, both of coffee had same temperatures since the plug was to obstruct spilling coffee.
