Which of the following statements regarding thermal conductivity is wrong? select one: o a. it is a transport property o b. it depends on the state of a matter o c. it depends on the temperature of a matter o d. the order of conductivity for different states is gas > liquid > solid

the wrong statement is

d) the order of conductivity for different states is gas > liquid > solid

Explanation:

the thermal conductivity is a property of materials that it values the ability to transmit heat through them. In general,  for metals and solid of continuos bodies the conductivity is high.

k = q / ΔT

∴ q: heat flux

∴ ΔT; temperature gradient

When a material undergoes changes of states, the thermal conductivity can change.  for example, the conductivity of frozen water (a 0°C) is higer than that of liquid waterfrom literature.
