The system is like a chemistry lab which breaks down complex proteins and starches into simple chemicals.

Suppose that during that icy hot lab 65,000 j of energy were transferred to 450 g of water at 20°c what would have have been the final temperature of the water

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.
