Correct Answer

C

Explanation

The qualities of a good thermometer include:

I. Reproducibility: A good thermometer should provide consistent and reproducible measurements. When the same temperature is measured repeatedly, the thermometer should yield similar results each time.

II. Sensitivity: A thermometer should be sensitive enough to detect small temperature changes accurately. This is especially important in scientific and industrial applications where precise temperature measurement is essential.

III. High thermal capacity: Thermometers with high thermal capacity can absorb and distribute heat effectively, leading to more stable and accurate readings. A high thermal capacity can reduce the impact of external factors and ensure the thermometer responds relatively slowly to temperature changes, which can be important in certain applications.

IV. High accuracy: Accuracy is a critical quality in a thermometer. It should provide measurements that are very close to the true or reference temperature. The accuracy of a thermometer is usually expressed as a percentage of the error compared to a known standard.

These qualities collectively contribute to the reliability and utility of a thermometer, whether it is used for everyday household purposes, scientific research, or industrial processes.
