The least count of a stopwatch
The least count of a stopwatch is the smallest time interval that can be measured using the stopwatch. It represents the accuracy of the stopwatch in measuring time intervals. In order to determine the least count of a stopwatch, we need to consider the number of divisions on the stopwatch and the range it covers.
Given information
In this experiment, the stopwatch has 20 divisions between the 0 to 10s marks. This means that the stopwatch can measure time intervals of 10 seconds with 20 divisions.
Determining the least count
To determine the least count of the stopwatch, we need to divide the range of measurement (10 seconds) by the number of divisions (20).
Least count = Range / Number of divisions
In this case, the range is 10 seconds and the number of divisions is 20. Plugging these values into the formula, we get:
Least count = 10 seconds / 20 divisions
Least count = 0.5 seconds/division
Therefore, the least count of the stopwatch is 0.5 seconds. This means that the stopwatch can measure time intervals with a precision of 0.5 seconds.
Significance of the least count
The least count of a stopwatch is important as it indicates the smallest time interval that can be accurately measured. It helps in determining the precision and accuracy of time measurements in experiments. In this experiment, knowing the least count of the stopwatch allows us to determine the boiling point of water with a certain level of accuracy.
Conclusion
The least count of the stopwatch used in the experiment to determine the boiling point of water is 0.5 seconds. This means that the stopwatch can measure time intervals with a precision of 0.5 seconds.
