Questions & Step-by-Step Solutions
A thermometer has a least count of 1°C. If the reading is 25°C, what is the maximum possible error in the measurement?
Steps
Concepts
Step 1: Understand what 'least count' means. It is the smallest value that can be measured by the thermometer.
Step 2: Identify the least count of the thermometer. In this case, it is 1°C.
Step 3: Recognize that the maximum possible error in a measurement is equal to the least count.
Step 4: Since the least count is 1°C, the maximum possible error in the reading of 25°C is also 1°C.
Least Count
– The smallest increment that can be measured by a measuring instrument, which indicates the precision of the measurement.
Maximum Possible Error
– The greatest deviation that can occur in a measurement, often equal to the least count of the measuring instrument.
