Answer:
The diffusion coefficients for iron in nickel are given at two temperatures:
T (K) 1273 1473
D (/s) 9.4 × 2.4 ×
(a) Determine the values of Do and the activation energy Qd.
(b) What is the magnitude of D at 1100°C (1373 K)?
<em>A </em>
<em>The pre-exponential factor Do = 2.1 x </em><em></em>
<em>The activation energy Qd = 252,609 J/mol</em>
<em>B</em>
<em>The diffusion coefficient D= 5.14 x </em><em></em>

Answer:
Applied pressure on piston (P) = 50 psi. We know that work done is given by W = Force x displacement. S Force = Pressure x Areas > W = ( PXA ) X L W = PX ( AL ) W = PX AV = 50x 43.7088. W= 2185.
