Question

why are liquids and gases poor conducters of heat?

Answer 1

Explanation:

Vibration energy of particles is less easily transmitted through a liquid and therefore liquids are usually poorer conductors of heat. Gases are very poor conductors of heat because their particles are widely separated so that collisions do not occur frequently to enable efficient energy transfer.

Answer 2

$\huge \fbox \pink{Answer}$

The liquids and gases poor conducters of heat because At atmospheric pressure, air and other gases are poor conductors (Insulators) of electricity. Because, they don't have any free electrons to carry current. But, once the free electrons are produced in gas by ionization (they become plasmas), electric discharge occurs.
