3.1.1 Calculating Density

• What is density defined as?

  Mass per unit volume
• Density is measured in kg/m³ or g/cm³.


  True
• To remember the density formula, use the phrase: Density is mass over volume
• What does density tell us about matter?

  How tightly packed matter is
• What are the standard units for measuring volume?

  m³ or cm³
• To calculate density, we need to measure mass and volume.
• The formula for density is: density = mass / volume
• What does the symbol 'm' represent in the density formula?

  Mass
• Arrange the following units from smallest to largest:

  1️⃣ g ||| kg ||| cm³ ||| m³
• Match the term with its unit:

  Mass ↔️ kg or g

  Volume ↔️ m³ or cm³
• 1 kg is equal to 1000 g.


  True
• Density is a fundamental property of materials.

  True
• To remember the density formula, use the phrase: Density is mass over volume
• Arrange the steps to measure volume by displacement:

  1️⃣ Immerse the object in water

  2️⃣ Measure the displaced volume
• Volume is measured in cubic meters or cubic centimeters.


  True
• Match the term with its symbol:

  Mass ↔️ m

  Volume ↔️ V
• The formula for density is: Density = Mass/Volume
• Calculate the density if the mass is 50 g and the volume is 20 cm³:

  1️⃣ Density = Mass/Volume

  2️⃣ Density = 50 g / 20 cm³

  3️⃣ Density = 2.5 g/cm³
• To calculate density, you divide the mass of an object by its volume
• The density formula is Density = Mass/Volume.


  True
• What is the symbol for density?

  ρ
• How is density defined in terms of mass and volume?

  Mass per unit volume
• Match the term with its definition:

  Density ↔️ Mass per unit volume

  Mass ↔️ Amount of substance

  Volume ↔️ Space occupied by a substance
• What is the volume of a cube with sides one meter long?

  m³
• To calculate density, you need to measure mass and volume.


  True
• What units are used to measure mass?

  Kilograms or grams
• To calculate the density of an object, you need to measure its mass and volume
• Accurate measurements of mass and volume are crucial for density calculations.


  True
• What are the units for density?

  kg/m³ or g/cm³
• It is essential to use the correct units when calculating density.


  True
• What is density defined as?

  Mass per unit volume
• If an object has a mass of 50 g and a volume of 20 cm³, its density is 2.5 g/cm³
