Si la demanda por un bien final es elástica, entonces la demanda de trabajo correspondiente también es elástica

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

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.
