Additional Practice Questions
Why is it important to understand the weight and volume of everyday objects?
easyAnswer: Understanding the weight and volume of everyday objects helps in making informed decisions when buying or using products, ensures accurate cooking and baking, helps in understanding transport and storage needs, and fosters a practical understanding of measurement in science and day-to-day life.
If you have a 1-liter bottle and need to fill it using only 250 ml and 500 ml measuring cups, how would you do it?
mediumAnswer: You would need to fill the 500 ml measuring cup twice to reach a total of 1000 ml, which is equivalent to 1 liter.
List the advantages of using standardized weights and measurements in trade.
mediumAnswer: Standardized weights and measurements ensure fairness in trade, eliminate confusion and disputes, provide consistency in product specifications, facilitate international trade, and ensure accuracy in scientific experiments.
How can you check if a weighing scale is correctly calibrated?
hardAnswer: To check if a weighing scale is correctly calibrated, place a standard weight on the scale and check if it reads the exact value. Alternatively, zero the scale and ensure it does not show any weight when empty.
Describe an experiment to compare the capacity of different containers using water.
mediumAnswer: Fill one container with water to its brim and pour the water into another container until it is full. Measure any leftover water. Repeat this with different containers and compare how much water each holds to deduce which has the greater capacity.
