Two samples of the same resin are pulled in tension at two different rates. One is pulled at 1 inch per minute and the other is pulled at 10 inches per minute. Discuss the differences in elongation you would expect, and explain why the differences occur
What will be an ideal response?
You would expect to see a higher elongation in the pieces that were pulled at a slower rate. The slower rate allows the polymer chains time necessary for disentanglement. The forces seen in this case are those of the secondary bonding. At a faster rate, the forces that you see are applied to the backbone of the molecule itself and are generally higher.

A tank of 
volume contains air at 25°C and 101.33 kPa. The tank is connected to a compressed-air line which supplies air at the constant conditions of 45°C and 1500 kPa. A valve in the line is cracked so that air flows slowly into the tank until the pressure equals the line pressure. If the process occurs slowly enough that the temperature in the tank remains at 25°C, how much heat is lost from the tank? Assume air to be an ideal gas for which
