A quantity of ice is mixed with a quantity of boiling water in a sealed, rigid, container that allows the exchange of energy between the ice–water mixture and the surroundings. The container was left at the room temperature for an hour. By that time the contents of the container reached equilibrium. State whether the total internal energy of the contents decreases, remains the same, or increases in this process. Make a similar statement about the total entropy of the contents. Explain your answers.

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
