Question 13

electrical conductivity

Answer 13

ability to allow a flow of charge through a material. Electrical insulators don’t allow electrons to flow

Question 14

thermal conductivity

Answer 14

ability to allow flow of heat through a material. thermal insulators don’t allow this

Question 15

fusibilty

Answer 15

ability to change into a liquid state at certain temperatures

Question 16

desnsity

Answer 16

the mass of a material per unit of volume in kg/ m^3

Question 17

optical

Answer 17

ability to absorb or reflect light in different ways, eg. transparent, opaque etc.

Question 18

magnetism

Answer 18

the force exerted by magnets when they attract or repel each other. it’s caused by the motion of electric charges. most ferrous metals are magnetic.

Question 19

biodegradability

Answer 19

descriptive of a material capable of being decomposed by bacteria or other living organisms and so avoiding pollution
