Question

why is conduction not possible in case of liquid and gases

Answer 1

Conduction can occur in solids_liquids and gases. Explain why solids and liquids are better conductors of heat than gases. The answer is simple: their atoms, or molecules that make them up, are closer together, so they can transfer energy between them much more efficiently.

Answer 2

Because in solid particles are close but in liquid and gas particles having some space in between them
