because the particles and atoms are spread out too far to allow heat to pass between them (heat is passed on when the atoms/particles hit each other) in a gas they rarely hit each other so therefore is a poor heat conductor =)
poor conducters of heat
they are poor electricity and heat conductors
bad conducters or poor conduct of heat and light energy
Things like wood, paper and plastic are poor conductors of thermal radiation.
Metals and some ceramics.
most metals are good conductors for heat.
yes
gases and many plastic materials
Gases. Especially if you keep it from circulating.
Gases are poor conductors of heat because the molecules in gases are far apart and have weak intermolecular forces. This makes it difficult for heat to be transferred between gas molecules, resulting in low thermal conductivity. Additionally, gases have low density compared to liquids and solids, which further contributes to their poor heat conductivity.
Poor conductors of heat are generally also poor conductors of electricity. These would include most gases, ceramics and man-made plastics. A vacuum will not conduct heat either.
Because have lower melting points and boiling points
