Answer #1

A substance can only conduct electricity if it contains charged particles (electrons or ions) that are free to move around. Eg: In solid sodium chloride, there are ions but these ions are locked into the ionic lattice and are unable to move.

a. true- both the conditions are satisfied.. have charged particles and free to move

b. true- both the conditions are satisfied.. have charged particles and are loose so it is free to move and conduct electricity.

c. false- charge particles are there, but it cant move freely... hence it wont conduct electric current.

d. false- if that material has charged particle and it is not free to move(as it is not mentioned) so it cant conduct.

e. true - trapped chaged particles are mostly movable(solution phase) so it can conduct electricity.( depends on phase, it may not conduct also).
