Chapter 1: Q. 1.25 (page 17)

List all the degrees of freedom, or as many as you can, for a molecule of water vapor. (Think carefully about the various ways in which the molecule can vibrate.)

Short Answer

Expert verified

Total degree of freedom for water vapor is 3.

Step by step solution

01

Given information

water vapor molecule is given.

02

Explanation

The H-O bonds enclose 105 degrees, so the molecule is definitely nonlinear.
The rotational modes are around three axes, two of them in the molecular plane and one perpendicular to it.
We can see these rotational axis in the figure as below

Give an example of a process in which no heat is added to a system, but its temperature increases. Then give an example of the opposite: a process in which heat is added to a system but its temperature does not change.

The enthalpy of combustion of a gallon (3.8 liters) of gasoline is about 31,000kcal. The enthalpy of combustion of an ounce28g of corn flakes is about100kcal. Compare the cost of gasoline to the cost of corn flakes, per calorie.

At about what pressure would the mean free path of an air molecule at room temperature equal 10cm, the size of a typical laboratory apparatus?

Consider a uniform rod of material whose temperature varies only along its length, in the xdirection. By considering the heat flowing from both directions into a small segment of length 螖x

derive the heat equation,

鈭�T鈭�t=K鈭�2T鈭�x2

where K=kt/c蚁i, cis the specific heat of the material, and 蚁is its density. (Assume that the only motion of energy is heat conduction within the rod; no energy enters or leaves along the sides.) Assuming that Kis independent of temperature, show that a solution of the heat equation is

T(x,t)=T0+Ate鈭�x2/4Kt,

where T0is a constant background temperature and Ais any constant. Sketch (or use a computer to plot) this solution as a function of x, for several values of t. Interpret this solution physically, and discuss in some detail how energy spreads through the rod as time passes.

Determine the Kelvin temperature for each of the following:

(a) human body temperature;

(b) the boiling point of water(at the standard pressure of 1 atm);

(c) the coldest day u can remember;

(d) the boiling point of liquid nitrogen(-196掳C);

(e) the melting point of lead(327掳C)
