A special mercury thermometer which reads in Celsius has a distance of 8.3 mm between each degree marking (for example: from 2°C to 3° is 8.3 mm). If the temperature in the morning was 62 °F and the temperature later on around lunch time was 92°F, how many mm did the level of the liquid travel up the thermometer? The sucrose (C12H22011) in sugarcane can react with with water to produce ethanol (C2H,O) and carbon dioxide. In this way, sugarcane...
