1.7 Material Properties Flashcards
What’s the Acronym to remember the 4 Physical properties of a Metal?
- D -Density
- E - Electrical Conductivity
- A - Absorbency
- T - Thermal Conductivity
- F - Fusibility
Write a Definition of Density?
- Density is the Material that is measured as mass per unit volume
Write a Definition of Fusibility?
- Fusibility is the Material’s Ability to be converted through heat to a Liquid State and Then Fused with another before Colling down.
What Would Happen is a Material has a high Fusibility?
- If a Material has a High Fusibility then they have low melting point so a small amount of heating is required to convert these Materials to liquids
Write a Definition of Absorbency?
- Absorbency is the Materials Ability to Absorb or take in an element like water,Electricity,Heat and Light.
What Types of Materials are Good for Absorbing and Give a Example?
- Fibres and Fabrics That are Absorbent are good at Soaking Up moisture.
- For Example: Paper towels are really good at this.
Write a Definition of Electrical Conductivity and Give a Example?
- Electrical Conductivity Is a Material’s Ability to conduct electricity.
- For Example:Gloves Have Electrical conductive fingerprints.
Write a Definition of Thermal Conductivity and Give a Example?
- Thermal Conductivity is The Materials Ability to conduct Heat.
- For Example: Pans are good at Thermal Conductivity.
Write a Definition of a Insulator and Name 1 Material that’s a good conductor and 1 Materials that’s a good insulator?
- A Insulator is a Material That does Not Have The Ability to Conduct Electric or Heat.
- Metal is a Good Conductor.
- And Plastic is a Good Insulator.
What’s The Acronym to Remember the 6 Working Properties of Metals
- S - Strengths
- E - Elasticity
- D - Ductility
- M - Malleability
- T - Toughness
- H - Hardness
Write a Definition of Strength and Give a Example?
- Strength is The Materials ability to Withstand force such as tension, Shear or Pressure.
- For Example: A Surfboards have the ability to withstand abrasion,denting and scratching.
Write a Definition of Toughness and Give a Example?
- Toughness is The Material’s Ability to Absorb Energy Through Shock Without Fracturing.
- For Example : a Bullet Proof Vest needs to Be Tough.
Write a Definition of Malleability and Give a Example?
- Malleability is the material’s ability to change shape under compression like bending.
- For Example : Gold in One of the most malleable materials on earth.
Write a Definition of Ductility and Give a Example?
- Ductility is The Ability to be Stretched out or drawn out into a thin wire strand without breaking.
- For Example : Sportswear.
Write a Definition of Brittle?
- Brittle is When a Material Breaks Easily.
