The energy content of different foods can be determined by combusting samples in a calorimeter. The water in the calorimeter absorbs the heat released by the combustion. Two trials are done with two snack foods. The mass and temperature changes of the water are shown in the following table. Assume that the calorimeter is perfectly insulated and all of the heat released is absorbed by the water. Sample Mass of Snack Mass of Water AT of Water Snack X 0.20 g 200. g 6.0°C Snack Y 0.80 g 200. g 12.0°C What conclusion can be drawn about the amount of energy released per gram of snack X compared with the amount released per gram of snack Y? A Snack X released twice as much energy per gram as snack Y did. Snack X released four times as much energy per gram as snack Y did. Snack Y released twice as much energy per gram as snack X did. Snack Y released four times as much energy per gram as snack X did.
