Question

matching. match the term on the left with the statement that best describes it on the right.
a property of metals, also called shiny a mixture of two metals, ex. brass or bronze a material that does not conduct heat or electricity a material that does not allow light to pass through the resistance of a liquid to flow

1. viscosity
2. luster
3. insulator
4. opaque
5. alloy

Explanation:

• 29. viscosity: Viscosity is defined as the resistance of a liquid to flow, so it matches "the resistance of a liquid to flow".
• 30. luster: Luster is a property of metals that makes them shiny, so it matches "a property of metals, also called 'shiny'".
• 31. insulator: An insulator is a material that does not conduct heat or electricity, so it matches "a material that does not conduct heat or electricity".
• 32. opaque: An opaque material does not allow light to pass through, so it matches "a material that does not allow light to pass through".
• 33. alloy: An alloy is a mixture of two metals (e.g., Brass or Bronze), so it matches "a mixture of two metals, ex. Brass or Bronze".

Answer:

1. viscosity - the resistance of a liquid to flow
2. luster - a property of metals, also called "shiny"
3. insulator - a material that does not conduct heat or electricity
4. opaque - a material that does not allow light to pass through
5. alloy - a mixture of two metals, ex. Brass or Bronze
