Answer 2

Answer:

Ice packed in sawdust does not melt quickly because it provides insulation.

Explanation:

Sawdust is the waste matter of wood formed in sawmills and timber works. We know that wood is a bad conductor of heat and a good insulator. The sawdust are so fine particles that they cover the ice block well and does not allow air to come in contact with ice. Thus, they help the ice to remain in solid-state and does not allow it to melt.
