What substance melt ice faster salt flour sugar?

Answer 1

Melting IceWater...It has the highest substance heat capacity i.e. water requires the largest loss of heat per mole to change phase (to freeze) and , (vice versa) ice requires the greatest amount of heat to change phase (to melt). all other things being constant, for example non-substances radiation and conduction heating.

Solutes

Calcium chloride is the fastest thing I've seen melt ice. They sell it as Dowflake.

Dowflake is nice because it's noncorrosive to metal, unlike salt. It's also really expensive.

Nitrates

A very well-disolving salt - try a nitrate. Nitrate is the definition of dissolvable.

The Question was Multiple Choice

If there was anything that would melt ice fast, it would be molten lava. In fact, it melts and vaporizes almost simultaneously. One of the best ways to melt ice at room temperature is to set it on a large block of aluminum, which loses heat rapidly to the air.

Answer 2

Any ice cube will melt if put in any temperature over 32*F because it will be over freezing point Any ice cube will melt if put in any temperature over 32*F because it will be over freezing point

Answer 3

Salt will help melt ice faster than will either sugar or flour. This is because salt is an electrolyte and ionizes into two or more ions (depending on which salt you use: NaCl gives 2 ions, CaCl2 gives 3 ions). Neither flour nor sugar ionize, so they are less effective in lowering the freezing point and melting the ice. This is all found under the topic of "colligative properties".

Answer 4

Salt will melt ice faster than flour or sugar because salt lowers the freezing point of water. This causes the ice to melt by creating a saltwater solution with a lower freezing point than pure water. Flour and sugar do not have the same effect on ice as salt.

Answer 5

Hot water, salt, and fire

Answer 6

Heat or humidity

Answer 7

Road salt
