The density of an object is dependent of an object?

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

When does your body conduct current more readily?

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?
