Understanding Triple Beam Balance Functions

This video tutorial explains how to use a triple beam balance to measure the mass of an object. It covers the components of the balance, including the three beams with different graduations, and provides detailed instructions on zeroing the balance and measuring mass accurately. The tutorial concludes with a demonstration of finding the final measurement of an object.

What is the primary function of a triple beam balance?

• To measure the volume of an object

• To measure the mass of an object

• To measure the length of an object

• To measure the temperature of an object

How many beams does a triple beam balance have?

• One

• Two

• Three

• Four

What is the graduation increment on the highest beam of a triple beam balance?

• 10 grams

• 100 grams

• 1 gram

• 1000 grams

What must be done to the balance before placing an object on it?

• Move all weights to the right

• Ensure the pointer is straight

• Add a counterweight

• Remove the pan

If the 100g weight causes the scale to shift, what should you do next?

• Adjust the counterweight

• Remove the object

• Move to the 10g beam

• Add more weight to the 100g beam

What should you do if the scale shifts when using the 10g beam?

• Move to the 1g beam

• Choose the increment 10 less than the shift

• Remove 10 grams

• Add 10 more grams

What is the purpose of the 1g beam on a triple beam balance?

• To measure large weights

• To hold the object

• To fine-tune the measurement

• To zero the balance

How do you know when you have found the final measurement on a triple beam balance?

• When the pointer is at the top

• When the scale is level at zero

• When the weights are all on the right

• When the pan is empty

What was the final weight measured in the activity?

• 120.5 grams

• 121.5 grams

• 122.5 grams

• 123.5 grams
