Technician A says that a good relay should measure between 60 and 100 ohms across the coil terminals. Technician B says that OL should be displayed on an ohmmeter when touching terminals 30 and 87. Which technician is correct?

Suppose the liquid phase consists of an equimolar mixture of compounds 1 and 2 at 350 K. Set up a system of equations that would allow you to calculate the pressure and composition of the vapor phase in equilibrium with this liquid at 350 K. You don’t need to solve the equations, but the number of equations and unknowns should be balanced such that they could be solved. You may assume the Margules parameters A12 and A21 are known even if you have no final answer to part A.

A pair of compounds identified as 1 and 2 have the following properties:
This pair of compounds forms an azeotrope at 350 K and P = 8.5 bar, with x1 = y1 = 0.31.

An engine has a warped cylinder head. Technician A says that this could be caused by running the engine with a faulty thermostat. Technician B says that this could be because the engine was overheated. Who is right?

A. ?Technician A only B. ?Technician B only C. ?Both A and B D. ?Neither A nor B
