Because we know the specific heat of water, we can use it to determine how much energy there is in coal. You can take a small amount of coal and burn it under a beaker of water. By measuring how much the temperature of the water went up, you can determine how much energy was released by the burning coal. Suppose that you burn a small chunk of coal (75g) under a beaker filled with 100g of water. The water is initially at room temperature (21C) and after the coal has completely burned the water is 46.5C. Calculate the initial and final kinetic energy of the water. Use the table below to organize your work. 8-1
