ice packed sawdust does not melt quickly why
Answers
Answer:
Sawdust acts as an insulator against the surrounding temperatures and helps maintain the low temperatures of ice, so ice is packed in sawdust always or sometimes in layers of sack cloth.
Explanation:
Ice packed in saw dust dosent melt quickly because the saw dust acts as a cushioner. it does not allow the air to hit the ice and also doesn't let the warmth of the ice get out.
Because Sawdust is a good insulator. that is it does not conduct heat easily, Which means that if you put it around ice the heat that melts it cant get to it very easily stopping it from melting. During the Australian gold rush they packed giant blocks of ice from the Canadian glaciers, in crates with sawdust around them in Canada. They would ship them to the Australian gold fields and sell it for its weight in gold for the miners drinks.
