Unformatted text preview: Fall 2006 Page 1 of 2 Excel Exam Sample Questions Problem 1, Sample 1. The volume (V [cubic centimeters, cc])) of a sphere is related to its radius (r [centimeters, cm]) by: 3 r 3 4 V π = (the units provided are consistent, requiring NO UNIT CONVERSION). An engineer experiments by blowing up a balloon underwater and measuring the radius as the balloon volume goes from 30 cc to 530 cc in increments of 20 cc. Calculate the theoretical value of the radius at each increment, and plot the results. Problem 2, Sample 2. The pressure (P [Pascals, Pa]), volume (V [Liters, L]), amount (n [gram-moles, gmol]), and temperature (T [Kelvin, K]) of an ideal gas are related by T R n V P = where R is the ideal gas constant: K gmol L Pa 8314 R = Note the units provided are consistent, requiring NO UNIT CONVERSION. An engineer expands a piston from 1 L to 3.5 L, taking data every 0.1 L. Calculate the theoretical effect on the pressure if n = 10 gmol and T = 350 K, and plot the results....
