How to Measure Density of Solids and Liquids

The video tutorial explains how to measure the density of different substances, including regular solids, irregular solids, and liquids. It covers the process of measuring mass and volume, using tools like balances, rulers, and measuring cylinders. For regular solids, dimensions are measured and multiplied to find volume. For irregular solids, water displacement is used. For liquids, the mass of the liquid is found by subtracting the mass of an empty cylinder from the filled one. The density is calculated by dividing mass by volume for each substance.

What is the first step in determining the density of a regular solid?

• Calculate the density directly

• Place the solid on a balance to find its mass

• Measure its volume using a ruler

• Use the water displacement method

How do you find the volume of an irregular solid?

• By calculating its density first

• By using the water displacement method

• By using a balance

• By measuring its dimensions with a ruler

What is the mass of the irregular solid in the example provided?

• 198.14 grams

• 56.42 grams

• 17.10 grams

• 72.03 grams

What is the first step in measuring the density of a liquid?

• Pour the liquid into a measuring cylinder

• Measure the mass of an empty measuring cylinder

• Calculate the volume of the liquid

• Use the water displacement method

What is the volume of the liquid used in the example?

• 180 cubic centimeters

• 250 cubic centimeters

• 150 cubic centimeters

• 200 cubic centimeters
