Measuring Mass with a Triple Beam Balance

The video tutorial explains how mass is measured using a balance, specifically focusing on a triple beam balance. It describes the principles of balancing an unknown mass against a known mass and demonstrates the process using chocolate chips, resulting in a measured mass of 17.8 grams.

What is a common tool used in science labs to measure mass?

• Barometer

• Microscope

• Balance

• Thermometer

How does a balance determine the mass of an object?

• By checking its temperature

• By comparing it to a known mass

• By observing its color

• By measuring its volume

What is the main principle behind the operation of a balance?

• It uses magnetic fields

• It compares an unknown mass to a known mass

• It measures the speed of an object

• It calculates the density of an object

What is a unique feature of a triple beam balance?

• It is used for measuring liquids

• It measures temperature

• It uses three beams with different weights

• It has a digital display

What was the mass of the chocolate chips measured in the example?

• 19.3 grams

• 17.8 grams

• 20.5 grams

• 15.2 grams
