Calculate the force of kinetic friction on a 12.3 kg mass if its coefficient of kinetic friction is 0.137

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.

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Drag each item into the proper state of matter category.
