Consider the dry adiabatic rate of DAR=10 Co/1000m, and the moistrate of MAR=6 Co/1000m

1. By how many degrees does air cool if it rises dry adiabaticallyfrom sea level to the top of the coastal range mountains (about 800meters)?
2. If cloudy air rises moist adiabatically 800 meters, how muchwould its temperature change be?
3.Why, specifically, does the temperature change at a differentrate for these two situations?

a diesel engine operates reversibly on the cycle abcda counterclockwise. a->b is isobaric (change in v >0) and c->d(change in p < 0) is isochoric. The cylce is using 9 moles of anideal gas with adiabatic constant = 1.5 paths bc (change in p<0, chng in v>0) and da (change in p >0,chng in v<0)are adiabatic. the operating temps of the points a,b,c,d are 375,450, 432, and 250 respectively. answer the following
A) What is the heat intake during the isobaric?
B) What is the heat rejected during the isochoric process?
C) What is the work performed by the engine during the adiabaticexpansion.
D) What is the Thermal Efficiency

In this problem you are to consider an adiabatic expansion of anideal diatomic gas, which means that the gas expands with noaddition or subtraction of heat.

This applet shows the adiabatic compression and expansion of anideal monatomic gas with \gamma=5/3. It will help you to see thequalitative behavior of adiabatic expansions, though your actualcalculations will use a slightly different gamma.

Assume that the gas is initially at pressure p_0, volume V_0, andtemperature T_0. In addition, assume that the temperature of thegas is such that you can neglect vibrational degrees of freedom.Thus, the ratio of heat capacities is \gamma=C_p/C_V=7/5.

Note that, unless explicitly stated, the variable gamma should notappear in your answers--if needed use the fact that \gamma=7/5 foran ideal diatomic gas.

A. Find an analytic expression for p(V), the pressure as a functionof volume, during the adiabatic expansion.
Express the pressure in terms of V and any or all of the giveninitial values p_0, T_0, and V_0.

B. At the end of the adiabatic expansion, the gas fills a newvolume V_1, where V_1 > V_0. Find W, the work done by the gas onthe container during the expansion.
Express the work in terms of p_0, V_0, and V_1. Your answer shouldnot depend on temperature.

C. Find Delta U, the change of internal energy of the gas duringthe adiabatic expansion from volume V_0 to volume V_1.
Express the change of internal energy in terms of p_0, V_0, and/orV_1.
