1.Solution gas drive oil reservoirs experience greater recovery efficiency than undersaturated reservoirs during primary recovery. This problem explores some aspects of ...

irs during primary recovery. This problem explores some aspects of this behavior. Consider the expansion of methane from 300 bars to 50 bars at a constant temperature of 40 C (313 K). Methane obeys the following equation of state V =(RT/P)+C+(D/T) where C = 31 cm3/mol, D = -693cm3K/mole, and R = 83.14bar cm3/mole K. Note that the units of energy are bar-cm3/mole in this problem. Report your answer in bar-cm3/mole (a) What is the change in enthalpy during the expansion (b) What is the change in internal energy? (c) What is the heat removed? (d) How much work does the system do during the expansion?

6.Criteria for evaluation can change depending on the times, circumstance, and most importantly, with audience. This assignment will focus ...

audience. This assignment will focus on how criteria can change and how you need to tailor your essay to these changing audiences. In good times, people may want homes with soaring entryways, lots of space and premium appliances. In tougher times, they may care more about efficient use of space, quality insulation, and energy efficient appliances. When gas prices are low, people love to buy SUVs and trucks, but when gas prices get higher, they prefer hybrid cars with good fuel efficiency. Think of two scenarios, much like the ones above, where different audiences or different times create different criteria for evaluation. For example, what impact might global warming have on the way we determine desirable places to live or vacation? How might a changing economy change the way we view successful careers? If people across the globe continue to put on weight, how might standards of beauty change? Si i have this assignment for English I just don't understand it here is the assignment: Explore two scenarios in which change might revise customary values and standards for evaluation. Each scenario should be a paragraph of at least 100 words in length.
