Question Description:

Compressing gases requires work and the resulting energy is usually converted to heat; if this heat does not escape, the gas’s temperature will rise. This effect is used in diesel engines: The compressed air gets so hot that when the fuel is injected, it ignites without any spark plugs. As an example, consider a cylinder in a diesel engine in which air is compressed to one twentieth of its original volume while the pressure rises from 1 atm to 59 atm (absolute, not gauge). Note that because the air heats up while being compressed, its pressure rises more than twenty-fold. If the air is taken into the cylinder at 23 ◦ C, how hot does it get after being compressed? Answer in units of ◦ C,Are you finished?,Are you finished with this problem yet? It is due in 20 minutes and I need it asap. THank you.,Nevermind, I already finished it. I dont need it anymore.
