Suppose we have a piece of a candy bar that has an initial mass of 28g.  If we ignite the piece of candy bar (literally burn it), and it increases the temperature of 285.23g of water from 18.95°C to 77.43°C, how many calories per gram of energy did the candy bar provide if the final mass of the marshmallow is 4.45?  Note: 1.00 cal = 4.184 J. Give your answer in units of cal/g.

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
