Hot molecules moving makes a good heat insulator
Marbles are not good insulators because they are made of dense material and can conduct heat easily. Insulators are materials that do not allow heat to flow through them easily, whereas marbles are more likely to transfer heat.
Insulators have tightly bound electrons that do not move freely. This makes it difficult for thermal energy (heat) to be transferred through the material via electron movement. Additionally, insulators have a molecular structure that impedes the transfer of heat through the material.
Insulator, same as for electricity. An example of insulators (of heat) is Styrofoam.
Trapped air makes a good insulator.
A good insulator is a substance that does not allow energy to flow very quickly when there is a temperature difference between two areas. The most important component of good insulators is stationary air because air is a poor conductor of heat. Good insulators contain millions of tiny air spaces, which slow heat conduction through them. Thus, the heat is "kept in" or "kept out". Insulators with a lower density means there is space between the particles/molecules of the material. Having the right density is critical in whether a material makes a good insulator or not. If there is not enough density, air will flow too quickly through the material; if the density is too high no air will be trapped in the material and cool air will flow quickly to the other side.

insulator. Insulators have low thermal conductivity, which means they are not good conductors of heat and help to slow down the transfer of heat. This property makes them useful for insulating buildings, electrical wires, and various other applications where heat needs to be retained or kept out.
A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. Air, cloth and rubber are good electrical insulators; feathers and wool make good thermal insulators.
Cuz of insufficient presense of electrons in the external shell of such material's atom

Good insulators prevent heat from getting through them by limiting the transfer of heat energy from one side of the material to the other. This is achieved by slowing down the movement of heat through the material via methods such as trapping air pockets or reducing thermal conductivity.
Yes, socks are good heat insulators because they trap heat close to the skin and prevent it from escaping. The insulation provided by socks helps to keep your feet warm by reducing heat loss to the surrounding environment. Wool socks are particularly effective at retaining heat due to the natural properties of the material.
An insulator is a material that does not transfer heat energy easily. Insulators have low thermal conductivity, which means they are poor conductors of heat. Examples of insulators include rubber, wood, and plastic.
