Answer: gamma and T.
- A Pressure mainly
- B Density mainly
- C gamma and T
- D Mass of gas mainly
Correct answer: C. gamma and T
Explanation: v = sqrt(gamma P/rho) = sqrt(gamma RT/M). Speed depends on gamma (ratio of specific heats) and temperature.
The Carnot cycle alternates two isothermal steps (heat absorbed at TH, released at TC) with two adiabatic steps (no heat exchange); the enclosed loop area equals the net work output, and η = 1−TC/TH is the maximum possible efficiency between those two temperatures.
