You must be able to convert units already!!

Main Assignment

Mass and Weight

Is it the same? Or is there a difference between them?

Explanation §2.3

Mass and Volume

Explanation §2.3

• Mass
  
• = How much substance an object contains
  

• Measuring:
• Scale
  

• Standard Unit:
  
• Kilogram (kg)
  

Explanation §2.3

• Mass
  
• = How much substance an object contains
  

• Measuring:
• Scale
  

• Standard Unit:
  
• Kilogram (kg)
  

Explanation §2.3

• Volume
  
• = How much space a object takes up
  

• Measuring
  

1. Calculating 
2. Experimentally
    

• Unit:
  
• Liter (L)
  

Explanation §2.3

• Calculating volume:
  
• Regular shaped objects
  

• Rectangular objects:
  
• 𝑉 = 𝑙 𝑥 w 𝑥 ℎ (Volume = length x width x height)
  

• Cylinder
  
• 𝑉 = 𝜋 𝑥 (𝑟^2) 𝑥 ℎ (Volume = pi x radius x radius x height

Explanation §2.3

• Calculating volume:
  
• Regular shaped objects
  

• Rectangular objects:
• 𝑉 = 𝑙 𝑥 w 𝑥 ℎ (Volume = length x width x height)
  

• Cylinder
  
• 𝑉 = 𝜋 𝑥 (𝑟^2) 𝑥 ℎ (Volume = pi x radius x radius x height

Using: cm, gives cm³

Using: dm, gives dm³

Explanation §2.3

• Calculating volume:

Explanation §2.3

• Experimentally:
  

• 'Immersion method'
• Irregular shaped objects

• Irregular shaped objects
  

Explanation §2.3

• Experimentally:
  

• 'Immersion method'
• Irregular shaped objects
  

Explanation §2.3

• Experimentally:
  

• 'Immersion method'
• Irregular shaped objects
  

• Volume = Finish level – Starting level:

85 mL – 65 mL = 20 mL

1 mL = 1 cm³

20 mL = 20 cm³

Let's Work

- Read section 3 

- Make the following exersises: 

   2.3: 21, 24, 25, 27, 28, 29, 30 (blue book)
