Answer to Question #217891 in Molecular Physics | Thermodynamics for Kurimaw

Question

For an otto cycle, at what process is heat added?

Answer 1

First, the gasoline-air mixture enters at point a (where [Volume]=rV), and then it is compressed adiabatically to be taken to volume V and point b. On the second step of the Otto cycle, the heat is added to the system (Q_H) along the line bc because the gasoline–air mixture is being burned.
