Why do chemicals work well to melt ice and prevent ice from forming?
They raise the melting point of water - preventing the water turning to ice.
Is ice melting ice a physical or chemical change?
melting ice a physical change
Why do saw dust or blanket can prevent ice to melt slower?
The sawdust acts as insulation. But styrofoam or a Dewar flask will work much better.
Is ice melting a chemical or physical changes?

Why does ice cubes melt faster under dark fabric?
The dark fabric absorbs heat - which is transferred to the ice cubes, melting them faster.
How do you prevent ice from melting?
Simple. You keep ice in dry ice. But be careful not to eat dry ice!
Why does salt prevent ice from forming on sidewalk?
salt lowers ice's melting point
What is the best substance to prevent ice from melting?
Substances (solutes) are added to water to prevent it from freezing, not to prevent it from melting. Nothing added to ice will raise its melting point above 0°C.However, anything that insulates ice from external heat will keep it frozen longer. This includes blankets, thermos bottles, or the walls of a freezer.
What would best prevent ice from melting plastic or steel?
tgf
How do you make a insulator that can not make ice melt?
to make an insulator prevent ice from not melting is to use tinfoil and dirt.
What insulates the ice cream to prevent it from melting in the hot dish baked Alaska?
nothing

What does melting ice do?
Melting ice turns the ice into water.

What effect does sugar have on ice?
yes but not to the same extent. solutes prevent ice formation by lowering the melting point of water. sugar water does have a lower melting point than pure water but it is not as effective as simpler salts because it is less soluble. (conc. of solutes is related to the melting point)
Is ice melting chemical reaction?
ice melting is a physical reaction
