Brewed coffee is often too hot to drink right away. You can cool it with an ice cube, but this dilutes it. Or you can buy a device that will cool your coffee without dilution - a 220 g aluminum cylinder that you take from your freezer and place in a mug of hot coffee. If the cylinder is cooled to -20∘C, a typical freezer temperature, and then dropped into a large cup of coffee (essentially water, with a mass...

Remember in experiment 2 you used boiling chips; can the boiling sticks be replaced by boiling chips in this experiment? Explain your answer. Experiment2: Determination of Alcohol content of Wine by Fractional Distillation Introduction If a mixture of ethanol and water are warmed you might expect the more volatile (lower boiling) ethanol to boil first and then the water. This is not exactly true. As the mixture is warmed all the molecules within the flask will gain energy. In fact...
