← ScienceWhich effect occurs within a diesel engine cylinder during adiabatic compression?
A)Increased gas temperature and pressure✓
B)Decreased gas temperature, constant pressure
C)Constant gas temperature, increased volume
D)Pressure decrease with stable temperature
💡 Explanation
Adiabatic compression raises temperature because volume reduction increases molecular collisions. Therefore, higher pressure and temperature occur rather than maintaining constant values; the adiabatic process prevents heat exchange.
