Physicists at CERN study the conditions present during the big bang by using machines to do what? A. super heat the air to produce new elements
B. super cool the air to create solid gases like hydrogen and helium
C. smash atoms into one another and study the results
D. separate atoms from their electrons

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.

Iwill give brainliest if you answer right : )
