Ice traps air pockets within its structure, which reduces the transfer of heat through conduction. The low thermal conductivity of ice makes it an effective insulator, slowing down the rate of heat transfer. Additionally, the phase change from solid ice to water absorbs heat energy, further aiding in its insulating properties.
It's not. When you put ice in a glass the glass quickly becomes cold. Glass actually is a good insulator because in the summer when you have the air conditioner on in your house, glass keeps the hot air out and the cool air in.
Two materials that act as good insulators are rubber and wool. Rubber is a good insulator because it has a high resistance to electrical current, while wool is a good insulator because of its ability to trap air and prevent heat transfer.
Ice is a poor conductor of heat because of its low thermal conductivity. When ice is present, it can act as an insulating barrier between two different temperatures, preventing the transfer of heat. This insulating property of ice is why it is commonly used in coolers and ice packs to keep items cold.
Dirty water is not a good insulator because impurities in the water can increase its conductivity, allowing electricity to flow more easily through it. Pure water, on the other hand, is a poor conductor of electricity and can act as an insulator.
To stop ice from melting you are going to have to stop heat getting to it so you need to wrap it in a good insulator. Wrapping the ice in bubble wrap or putting it in a box made from polystyrene foam would work well, the thicker the insulator the better! A waterproof insulator is good because water is quite a good conductor of heat, if you say wrapped it in straw then the water released from the first bit of ice would soak into the straw and make it a less good insulator allowing more ice to melt. You could get around this by putting the ice in a plastic bag and wrapping the bag in an insulator that wasn't waterproof. For any container the more ice you have in it at the start the longer some will last. Ice can be kept in a high quality vacuum flask for quite a long time but if you are looking to make it yourself then it would be far from simple.
ice crem is gode
The ice layer act as an insulator.
No, Ice is a good insulator and copper is a very good conductor
Ice is readily available for them, and it is a good insulator.
YES!... newspaper is a good insulator... Try wrapping newspapers around ice cream boxes... there is a big possibility that it'll stay cold.
Insulator
The newspaper insulates the ice from heat.

Diode is a semiconductor material. so it act as insulator also.

some household items are:StyrofoamSawdustFiberglassTin foil (this reflects light but will melt the ice if it is touching it)
