Chapter 12: Q12.108P (page 497)

How does the random coil shape relate to the radius of gyration of a polymer chain?

Short Answer

Expert verified

To determine the size of the coiled chain polymer the radius of gyration is used.

Step by step solution

01

Definition

It is defined as the average distance between the center of mass of the molecule and the outer edge of the coil.

02

Concept 

The radius of gyration of the macromolecule is more meaningful as

it gives a sense of the size of the polymer coil, instead of the end-end distance.

Hence, the square radius of gyration is the average squared distance of any point in the object (polymer coil) from its center of mass.

Question: On a humid day in New Orleans, the temperature is , and the partial pressure of water vapor in the air is 31.0 torr. The 9000-ton air-conditioning system in the Louisiana Superdome maintains an inside air temperature of also, but a partial pressure of water vapor of 10.0 torr. The volume of air in the dome is , and the total pressure inside and outside the dome are both 1.0 atm.

a. What mass of water (in metric tons) must be removed every time the inside air is completely replaced with outside air?

(Hint: How many moles of gas are in the dome? How many moles of water vapor? How many moles of dry air? How many moles of outside air must be added to the air in the dome to simulate the composition of outside air?)

b. Find the heat released when this mass of water condenses.
