The compression ratio of an Otto cycle as shown in the figure below is VA/VB = 6.00. At the beginning A of the compression process, 525 cm3 of gas is at 110 kPa and 20.0°C. At the beginning of the adiabatic expansion, the temperature is TC = 730°C. Model the working fluid as an ideal gas with γ = 1.40.

Apositive rod is placed to the left of sphere a, and the spheres are separated. which best describes the spheres? sphere a is negative and sphere b is positive because protons from sphere a are attracted to the rod and move to sphere b. sphere a is negative and sphere b is positive because electrons from sphere b are attracted to the rod and move to sphere a. sphere a is positive and sphere b is negative because electrons from the rod move to sphere b and protons then move to sphere a. sphere a is positive and sphere b is negative because protons move from sphere b to the rod and also to sphere a.
