How is Young’s modulus of a material defined? A. It is the ratio of shear stress to shear strain.
B. It is the ratio of tensile stress to tensile strain
C. It is the force per unit area acting on the material’s surface.
D. It is the ratio of change in length to the material’s original length.

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

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false
