A1.0 g sample of a cashew was burned in a calorimeter containing 1000. g of water, and the temperature of the water changed from 20.0°c to 25.0°c. in another experiment, a 3.0 g sample of a marshmallow was burned in a calorimeter containing 2000. g of water, and the temperature of the water changed from 25.0°c to 30.0°c. based on the data, which of the following can be concluded about the energy content for 1.0 g of each of the two substances? (the specific heat of water is 4.2 j/(g⋅° (a) the combustion of 1.0 g of cashew releases less energy than the combustion of 1.0 g of marshmallow. (b) the combustion of 1.0 g of cashew releases the same amount of energy as the^combustion of 1.0 g of marshmallow. (c) the combustion of 1.0 g of cashew releases more energy than the combustion of 1.0g of marshmallow. (d) no comparison can be made because the two systems started with different masses of food, different masses of water, and different initial temperatures.
