A 25 kg aluminium ingot (initially at 72 °C), and a 50 kg fireclay brick (initially at 68 °C)) are lowered into a large water reservoir at 16 °C. Both the aluminium ingot and fireclay brick reach the same temperature as the water, due to heat transfer between the blocks and the reservoir water. (a) Determine the total entropy change for this process. (b) With the aid of a diagram, briefly discuss the reversibility/irreversibility of all the heat transfer processes...

In a steel plant, a 25g block of iron at 175 ˚C is dropped into 1 L of water at 20 ˚C in an insulated flask at atmospheric pressure. Calculate the final temperature of the system. The specific heat of iron is given by Ĥ(J/g)=17.3T(˚C). What reference temperature was used as a basis for the entalpy formula? Calculate the final temperature of the flask contents, assuming that the process is adiabatic, negligible evaporation of water occurs, negligile heat is transferred...

Question: You have 100g of water at 30C to which you add 50g of ice at 0C. Calculate the entropy change for the process. For this problem I solved for the final temperature, Tf, and got that it is equal to 17.333 C = 290.483 K I have to solve for the change in entropy, though. How would I go about doing this? I was going to either use the formula: Delta S = n*Cp(molar)*ln(Tf/Ti) with n = (150/18.016 mols...

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...

Argentina and Ecuador: Understanding the Currency Crisis While fiscal policy is never far from the mind of your average Argentine, who remembers the tough times and hyperinflation of the 1980s, the events of 2001 and 2002 have brought fiscal policy back to the forefront of public concern. Though the early 1990s may have been characterized by financial optimism, Argentina has been in a recession since Brazil's 1998 monetary crisis sent shockwaves across the regional and global markets. In early 2002,...
