The enthalpy of formation of ethanol (c2h5oh (g)) is -235,310 kj/kmol at the reference state. ethanol and air enter an adiabatic combustor at 25 °c and 100 kpa, and complete combustion with 200% excess air occurs. determine the final temperature of the combustion products.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
