Which one among the following statements about thermal conductivity is...
Thermal conductivity means that a substance has a capacity to conduct heat and electricity or it just let heat and electricity to pass through its own body.
Among all three steel is a good conductor of electricity hence current can easily pass through it and have low resistance compared to wood and water hence it will have highest conductivity whereas water may or may not conduct electricity depends upon amount of salts or impurity present but compared to wood it will have less resistivity hence it will have higher conductivity compared to wood but far less than iron.

Hence the correct order is Steel > water > wood
