What is the best method, other than heat, to melt ice?

Question

?????????????????????????????????????????????

Answer 1

Hi sweetie, gotta use salt. I'm not sure of the chemistry but it really do melt the ice. Hah, pple do use salt to kill snails too..I donno why? Gee

Answer 2

To melt ice you have to do one of two things: 1) raise the temperature of the ice or 2) lower the freezing point of the water. Now since you've ruled out using heat, you are left with only the option of lowering the freezing point (chemically) to return the water to a liquid state. This method will work fine if it's ok that you don't end up with pure water. Pouring salt on ice will melt it as salt water has a lower melting point than ice. This is why salt is mixed with ice in an home ice cream maker. As the ice melts, it absorbs heat and freezes the ice cream. Road crews used to put salt on bridges but, since salt promotes rust, other chemical compounds to melt ice (with out heat) have been developed

Answer 3

All of the other answers given so far use heat, so they do not really answwer the question. Even adding salt or sugar, is a colligative property. It lowers the freezing point, but you still need heat to convert the solid into a liquid.

One more solution is to reduce the pressure. The phase diagram for water shows the transition pressures between solid and liquid at different temperatures. If yu lower the pressure enough, the molecules will change phase from solid to liquid without the addition of any heat energy

Answer 4

no method. heat will be used in any case. if the heat is not provided by you, it will be taken from the environment.
salt will melt is by lowering its melting point....
putting the ice cube under running water.....heat will be taken from the water.

there is, however, one way. this is practically impossible but theoretically its cent percent correct. apply high pressure on the ice cube. (in labs when we apply high pressure, the temperature is lowered continuously as a lot of heat is generated in applying pressure)

Answer 5

poor sugar or salt over the ice. I don't know good question

Answer 6

you can't with simple methods. heat will be used somewhere ( natural )
hi -fi method - pass electricity

















aint it the best answer?

Answer 7

Just put ice in ur mouth !

Answer 8

run it under cold water.
it might take longer but it will melt it.

Answer 9

Pour salt on the ice..........

Answer 10

i think presuure
e.g u can see in skating
