an electrical insulator blocks the flow of electricity (like the rubber around power cords that stop you from getting electrecuted) and a heat insulator block the flow of heat (like a thermos)
A good insulator is good at stopping heat escaping, whereas a bad insulator is not very good at trapping heat and lets it out.
An alternative term for thermal insulator is "heat insulator." It refers to a material or device that reduces the transfer of heat energy between two surfaces or objects.
A conductor allows heat to flow easily through it due to its high thermal conductivity, while an insulator restricts the flow of heat due to its low thermal conductivity. Conductors are typically materials like metals, while insulators are materials like rubber or wood.
Fiberglass is a good insulator of heat. It is often used in homes and buildings to help regulate temperature by reducing the transfer of heat between different spaces.
A thermal insulator is totally incapable of answering this question
a potato is not an heat insulator because it's skin,but if you take the skin off it will be a heat insulator
A heat insulator is used to reduce the transfer of heat between two objects or areas. It helps to maintain a desired temperature by trapping heat inside or preventing heat from entering, such as in the walls of a house or in the handle of a pot.
outer electrons of the atoms in a metal are not anchored to the nuclei of particular atoms, but are free to roam in the material. such materials are good conductors.
A heat conductor allows heat to flow easily through it due to the movement of free electrons, such as metals. An insulator, on the other hand, inhibits the flow of heat due to the lack of free electrons or tight bonding between atoms, such as rubber or wood.
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator
newspaper is a good insulator because it will trap the heat in the thickness of the newspaper. it isn't always a good insulator because it can get wet and tear so therefor it will let heat out
An insulator is a material that does not allow heat to pass through easily, while a good conductor of heat is a material that allows heat to pass through easily. Insulators have low thermal conductivity, while good conductors have high thermal conductivity. Materials like rubber and wood are examples of insulators, while metals like copper and aluminum are good conductors of heat.
