a) Describe thermodynamically what occurs when a gas expands adiabatically in a refrigeration cycle. Include a detailed p-v sketch with labels for the state and condition. What happens to v, T, h, s? What does it mean for a thermodynamic process to be reversible? b)Given a thermodynamic power cycle, where a gas in a piston-cylinder system is expanded with irreversibilities, sketch a detailed p-v diagram comparing it to a Carnot cycle. Label all necessary states and conditions to appropriately describe...

A refrigerator is constructed with a Carnot engine. Draw a diagram of the Carnot cycle in a P-V diagram, label the components, and then detail the processes that occur (I short phrase each is all that is necessary). Draw a diagram of the Carnot cycle in a H-S diagram, and label it to match (a) Note: His enthalpy and S is entropy. Water is brought to 0 °C in the refrigerator with the heat being discharged into a reservoir at...

Schematically show, on a T-s diagram, an ideal refrigeration cycle vs. a real refrigeration cycle. Explain what modifications are necessary in order to convert a refrigeration cycle into a heat pump. What are some advantages and disadvantages of a heat pump? How do they compare with other heating systems? Do you think a heat pump will be more effective in New York City or Miami? Why?

Explain what parsimony is and why it is preferred in comstructing phylogenetic trees. Under optimal conditions, all the methods discussed [parsimony, maximum likelihood, neighbor joining akr bayesian inference reveal the true branching pattern of the phylogeny in question with accuracies appraoching 100%. However, real phylogenies are rarely inferred under ideal circumstances. Explain, using examples, why this is so.
