Using a Triple Beam Balance Effectively

What is the primary function of the triple beam balance?

• To measure length

• To measure temperature

• To measure the mass of objects

• To measure the volume of liquids

What is the name of the metal bracket on each beam of the triple beam balance?

• Poise

• Knob

• Scale

• Pointer

What should you do if the line on the beams does not match up with the zero on the right-hand side?

• Add more weight

• Turn the adjustment knob

• Ignore it and proceed

• Remove some weight

Which poise should you start with when measuring the mass of an item?

• The 100 gram poise

• The smallest poise

• The 1 gram poise

• The 10 gram poise

What does it mean if the hash mark dips below zero when using a poise?

• You need to add more weight

• You need to remove some weight

• The balance is broken

• You do not need to use that poise

What is the approximate mass of the paperclip measured in the video?

• 100 grams

• 1 gram

• 0.5 grams

• 10 grams

What is the first step when measuring a heavier object like an Erlenmeyer flask?

• Move the 10 gram poise

• Move the 1 gram poise

• Move the 100 gram poise

• Move the smallest poise

What should you do if the balance dips below zero when the 100 gram poise is moved to 200 grams?

• Move it back to 100 grams

• Move it to 50 grams

• Move it to 300 grams

• Move it to 150 grams

What is the total mass of the Erlenmeyer flask measured in the video?

• 123.5 grams

• 120 grams

• 110 grams

• 100 grams

Why is it important to make slight adjustments carefully when using the smallest poise?

• It can change the volume

• It can change the temperature

• It can affect the accuracy of the measurement

• It can break the balance
