A. if 0.96 kg of iron at 120°c is added to 0.75 kg of water at 20°c, what will be the final temperature of the system?

b. by touching the side of a beaker, a student concludes that an endothermic change is taking place inside it. write 2 - 3 sentences explaining how the student came to that conclusion and comparing the energy o the products of an endothermic reaction with the energy of the reactants.

c. as a substance freezes, its temperature does not change. how does the potential energy of the molecules of the substance change as a result of the heat released? what type of energy must decrease in order for the temperature to decrease?
