- A 310 cm3 cup of coffee cools from 88∘C to the 20∘C temperature of the room. Assume that the temperature of the room does not change and coffee has the same specific heat and density as water. What is the entropy change of the coffee? Of the room? Of the universeThe principle of increasing entropy Entropy principle: "For all irreversible processes, the change in entropy of the universe is positive." To prove the principle can be taken the case of reversible adibatic process. AS = Sf - Si Prove that the entropy of the universe is positive: E4S 2 0Write a crazy physics question that you can answer using thermodynamics. For example: How high would I have to jump to warm up the surface of the Earth upon landing? How long would I have to stir my coffee to make it hot again? How long would my car need to skid to melt my tires?
- By considering the number of accessible states for an ideal two-dimensional gas made up of N adsorbed molecules on a surface of area A, obtain an expression for the entropy of a system of this kind. Use the entropy expression to obtain the equation of state in terms of N, A, and the force per unit length F. What is the specific heat of the two-dimensional gas at constant area?Polymers, like rubber, are made of very long molecules, usually tangled up in a configuration that has lots of entropy. As a very crude model of a rubber band, consider a chain of N links, each of length L Imagine that each link has only two possible states, pointing either left or right. The total length L of the rubber band is the net displacement from the beginning of the first link to the end of the last link. Using the thermodynamic identity, you can now express the tension force F in terms of a partial derivative of the entropy. From this expression, compute the tension in terms of L, T , N, and l.
