Highest
thermal conductivity is of ________ .
solid ice
melting ice
water
steam
solid ice
Thermal conductivity of given option are :
Solid ice 2.25W/ Mk
Melting ice less than 2.22
Water 0.55 - 0.7
Steam 0.0142W/ Mk
Therefore, the highest thermal conductivity is of solid ice.
K solid > K liquid > K gas
(Due to shape and size of matter or orientation
of atom in molecules)
Hence, the correct option is (A).
