Kim made three measurements of her cell’s potential: 1.11 V, 0.00 V, and 1.12 V.

Final answer:

Kim's potential measurements of 1.11 V and 1.12 V are consistent with normal cell operation, while the 0.00 V indicates a likely disconnection or error during measurement.

Step-by-step explanation:

Kim's measurements of her cell's potential, which are 1.11 V, 0.00 V, and 1.12 V, indicate a pattern where two measurements are very close to each other and indicative of the cell's potential, while one is an outlier at 0.00 V. This outlier could be due to several factors, such as a disconnection in the circuit, measuring error, or a temporary failure within the cell itself. Realistically, when measuring terminal voltage, one should expect some minor variations due to internal resistance of the cell or changes in contact resistance during measurement. However, a reading of 0.00 V suggests an anomaly, possibly indicating a complete interruption of the circuit at the time of that particular measurement. The other two readings are consistent with what one would expect from a cell under normal conditions and without any significant internal resistance affecting the measurements.
