Two moles of carbon monoxide (CO) start at a pressure of 1.5 atm and a volume of 29 liters . The gas is then compressed adiabatically to 13 this volume. Assume that the gas may be treated as ideal.

(a) What is the change in the internal energy of the gas? Does the internal energy increase or decrease?
(b) Does the temperature of the gas increase or decrease during this process? Explain.

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.
