Question

a thermometer consistently reads 2°c higher than the actual temperature. what type of error is this, and how can it be minimized? random error; use a different thermometer systematic error; recalibrate the thermometer systematic error; take the average of readings random error; repeat measurements

Explanation:

Systematic errors are consistent and repeatable. Since the thermometer consistently reads 2°C higher, it's a systematic error. To minimize it, the thermometer should be recalibrated to correct the offset.

Answer:

Systematic error; recalibrate the thermometer
