Question

Ice wrapped in a blanket or saw dust does not melt quickly

Answer 1

Both wood and wool are bad conductors of heat. They do not permit heat rays to reach the ice easily. they are natural insulators - like a thermos - but they do not stop it from melting, they only slow down the process.

Answer 2

This is because saw dust and blanket are non conductors of heat energy.

Heat energy is required to melt ice.

Therefore,ice melts gradually.
