Mendeleev’s table and the modern periodic table organize the elements based on different information, yet most elements are in the same order in both tables. Explain why

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.

What efficiency of a car's engine when heat input is 200,000 joules and waste heat is 150,000 joules? a. 75% b. 35% c. 25% d. 85%

If 130 j of energy were added to 1 kg of each of the samples listed in the answer choices, which would experience the greatest temperature increase
