Which risk increases the most when a temperature sensor's analog-to-digital converter (ADC) exhibits increased nonlinearity within a closed-loop thermal control system?

💡 Explanation

Unanticipated thermal runaway becomes more likely because increased ADC nonlinearity causes inaccurate temperature readings, activating the heating element at incorrect times via proportional-integral-derivative (PID) control; therefore, the system exceeds safe limits rather than maintaining target temperature set-points.
