Please help give points.

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.

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?
