Homework #3 – Due Friday, September 17 1. Simple values and numbers – time to learn/memorize these important constants and typical values. These are considered “fundamentals” and it will be assumed that you know these values on exams, in life, etc. Those that are not known, you will need to learn where to find in the library (or as abslolute last resort on the WEB). 1 standard atmosphere of pressure in (a) Pascal, (b) bars, and (c) psi: The difference between psia and psig. Molar volume (in cm 3 /mole) of typical solids (Al and Fe), liquids (H 2 O and ethanol) and gases (say N 2 at 298 K, 1 atm). Typical coefficients of linear expansion for inorganic solids (Fe), polymers (PET - polyethylenetereph- thalate), liquids (water at 4 o C), and gases (O 2 ) at 298 K, 1 atm. What is the PRECISE definition of the calorie? How many different types of calories units can you find? The gas constant R in units of J/K-mole, cal/K-mole, l-atm/K-mole. 2. The ideal gas law is a very simplistic description of matter. A slightly better approximation is the van der Waals equation P + a v 2 · ( v - b ) = RT where a and b are constants (given for common gasses in table 8.1 of your text or in the CRC). For H 2 , the van der Waals constants are a = 0 . 2461 l 2 -atm/mole 2 and b = 0 . 02668 l /mole. One hundred moles of H
