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 correct order is solid > liquid > gas

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 water ... from literature.
