Using a Triple Beam Balance

Rachel explains how to use a triple beam balance to measure grams. She covers the importance of measuring the tare weight of the container, ensuring the balance is calibrated to zero, and understanding the scale's divisions. An example is provided to demonstrate the process of measuring an object's weight accurately. The video concludes with a reminder to measure twice for accuracy.

What is the primary use of a triple beam balance?

• To measure grams

• To measure volume

• To measure length

• To measure temperature

Why is it important to measure the container separately before measuring the contents?

• To verify the container's material

• To subtract the container's weight from the total

• To check if the container is empty

• To ensure the container is clean

What should you do if the triple beam balance does not start at zero?

• Ignore it and proceed

• Adjust it to zero

• Remove the container

• Add extra weight

What is the increment of the front scale on a triple beam balance?

• 10 grams

• 500 grams

• 100 grams

• 1 gram

How many grams does the back scale measure in increments?

• 50 grams

• 1 gram

• 10 grams

• 5 grams

What is the maximum weight the middle scale can measure?

• 100 grams

• 200 grams

• 500 grams

• 300 grams

What is the first step in using a triple beam balance to measure an object?

• Move the front scale

• Move the back scale

• Move the middle scale

• Adjust the balance to zero

If an object weighs 348 grams, how would you set the scales?

• 300 on middle, 48 on back, 0 on front

• 300 on middle, 40 on back, 8 on front

• 300 on back, 40 on middle, 8 on front

• 300 on front, 40 on back, 8 on middle

Why is it recommended to measure twice when using a triple beam balance?

• To verify the weight of the container

• To check the balance's calibration

• To ensure the balance is clean

• To confirm the accuracy of the measurement

What should you do after measuring the weight of the container and its contents?

• Divide the weights

• Add the weights together

• Subtract the container's weight

• Multiply the weights
