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.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
