Question
Chapter 13, Problem 13.29PAE
Interpretation Introduction
Interpretation:
Gold should used in pin manufacturing instead of copper. Explain.
Concept Introduction:
- Electroplating: It is a process which uses
electric current to decrease dissolved metal cations so that they produce a thin metal (coherent) coating on an electrode. - Electroplating changes the mechanical, chemical and physical properties of the workpiece.
- Electroplating of gold on nickel-plated circuits reduces the contact resistance as well as the surface hardness.

110. Compare the pressures given by (a) the ideal gas law, (b) the van der Waals equation, and
(c) the Redlic-Kwong equation for propane at 400 K and p = 10.62 mol dm³. The van der
Waals parameters for propane are a = 9.3919 dm6 bar mol-2 and b = 0.090494 dm³ mol−1.
The Redlich-Kwong parameters are A = 183.02 dm bar mol-2 and B =
0.062723 dm³ mol-1. The experimental value is 400 bar.
Research in surface science is carried out using stainless steel ultra-high vacuum chambers with pressures as low as 10-12 torr. How many molecules are there in a 1.00 cm3 volume at this pressure and at a temperature of 300 K? For comparison, calculate the number of molecules in a 1.00 cm3 volume at atmospheric pressure and room temperature. In outer space the pressure is approximately 1.3 x 10-11 Pa and the temperature is approximately 2.7 K (determined using the blackbody radiation of the universe). How many molecules would you expect find in 1.00 cm3 of outer space?
