Write 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?
An object can have its entropy decrease only if... O heat flows into the object. O work is done on the object. O There is no way for an object have its entropy decrease. O something else has its entropy increase by at least as much.
What would happen to the entropy of a system if you could increase the pressure without changing the temperature, volume, or number of particles?
The first law of thermodynamics is generally thought to be the least demanding to grasp, as it is an extension of the law of conservation of energy, meaning that energy can be neither created nor destroyed. (a) The variations of properties during phase change processes are best studied and understood with the help of property diagrams. Point out schematically the difference between the P-v diagram in respective of: 1. contracts on freezing. ii. expands on freezing.
(a) What is the unit of "specific entropy"? Is it an extensive property? (b) What is an isentropic process? Please give an example. (c) Explain the increase of entropy principle. (d) The entropy of a hot baked pizza decreases as it cools. Is this a violation of the increase of entropy principle? Explain.
What is the internal energy of a thermodynamic system?
Please describe to me the laws of thermodynamics. There are a certain number of them and therefore you must have all of them. Each should be labeled with it's number. For instance "The First Law of thermodynamics says that..."
