The questions are Which method of heat transfer is illustrated in this experiment? Explain your answer. How does the method of heat transfer used in this experiment differ from other methods of heat transfer?
Which substance do you think had the highest temperature after ten minutes? Explain your answer.
Which substance do you think cooled the slowest? Explain your answer.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
