Which of the following is most like an increased demand occupation in the greening economy? When a flooding problem threatens the anthill, many worker ants gather to dam off the threat. As nearby food sources disappear, worker ants go farther away for new sources. If ants from a larger colony attack, worker ants join the fight alongside soldier ants. A mutation makes worker ants in a specific area better capable of resisting rising temperatures.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Agas is compressed from vi 0.3 m, p 1 bar to of v2 0.1 m3, p2--3 bar. pressure and volume are related linearly during the process. for the gas, find the work, in kj.

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
