learning task 1: Match the definition in column A with the correct terms in column B.
Column A:
1.) the capacity to undergo a change of physical form without breaking.
2.) the resistance of a material to deformation of an indenter of specific size and shape under a known load.
3.) Occurs between metals and nonmetals.
4.) the measure of the ease at which an electric charge or heat can pass through a material.
5.) A property referring to the ability for a given substance,the solute, to dissolve in a solvent.
Column B:
A. Accuracy
B. Conductivity
C. Ductility
D. Solubility
E. Boiling Point
F. Ionic Bond
G. Hardness
Answers & Comments
Answer:
1. Ductility
2. Hardness
3. Ionic Bond
4. Conductivity
5. Solubility
Explanation:
1. Ductility is a mechanical property of a material to be amenable to drawing or be plastically deformed without breaking or fracture.
2. Hardness is the materials resistance to deformation. It is the ability of a material to resist penetration of its surface. Usually the harder a material is, the lower its ductility.
3. Ionic bond is formed when a metal and a non-metal exchange electrons. This is formed between a cation, which is usually from a metal, and an anion, which is usually from a non-metal.
4. Conductivity in metals is the measurement of a material’s ability to transmit heat or electricity.
5. Solubility is a property that refers to the ability of a solute to dissolve in a solvent. It is measured by the maximum amount of solute dissolved in a solvent at equilibrium resulting to a saturated solution.
