Deing an appropriate sketched p-v diagram, outline the four stages of the carnot cycle. 2he upper temperature of the engine is 330 k; the lower temperature is (1 marks) 278 k (0/ annotate your sketched diagram in 3(a) with this information. calculate the thermodynamic efficiency of the engine. (4 marks) (c) the isothermal expansion stage of the engine increases the volume o mole of an ideal gas present in the engine from 400 cm3 to 600 cm ( given that the expansion is reversible, what is the work done by the engine in this stage? (3 marks) use the information given in 3(b) and your answer in 3(c)(0) to calculate the entropy change of the engine in this stage of the expansion. (ii) (5 marks) (ii) use the information given in 3(b) to calculate the final volume of the engine, after both expansions.

explanation:

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
