FAQs on Detailed Video: Significant Figures & Dimensions Video Lecture - Chemistry for JEE Main & Advanced
| 1. What are significant figures? |  |
Ans. Significant figures are the digits in a number that carry meaningful information about the precision of the measurement. These digits include all the certain digits plus one uncertain or estimated digit.
| 2. How do you determine the number of significant figures in a measurement? | |
Ans. To determine the number of significant figures in a measurement, follow these rules:
- Non-zero digits are always significant.
- Zeros between non-zero digits are significant.
- Leading zeros (zeros at the beginning of a number) are not significant.
- Trailing zeros (zeros at the end of a number) are significant if there is a decimal point present.
- Trailing zeros without a decimal point are not significant.
| 3. Why are significant figures important in scientific measurements? | |
Ans. Significant figures are important in scientific measurements because they provide information about the precision of the measurement. They help convey the level of certainty or uncertainty in a measured value. Properly reporting significant figures ensures accuracy and consistency in scientific calculations and data analysis.
| 4. How do significant figures affect mathematical operations? | |
Ans. When performing mathematical operations with measured values, the result should be rounded to match the least number of significant figures in the calculation. Addition and subtraction require the result to be rounded to the least number of decimal places, while multiplication and division require the result to be rounded to the least number of significant figures.
| 5. What is the importance of considering dimensions in scientific calculations? | |
Ans. Considering dimensions in scientific calculations is crucial because it helps ensure the consistency and accuracy of the calculations. Dimensions represent the physical quantities being measured, such as length, time, mass, etc. By properly considering dimensions, scientists can check for dimensional consistency and identify errors in equations or calculations. It also aids in unit conversions and understanding the relationships between different physical quantities.
