how to make hot ice without melting?

Dry ice isn't really ice at all; it is solid carbon dioxide.   It is -78C and the smokey vapour isn't CO2, it is water vapour that has been cooled by the dry ice.  Dry ice doesn't really melt either, it sublimes from solid to gas.

ICE..keep the ice on it for a while trust it works FAST

It's ALMOST impossible as there are so many fast ways to PRODUCE heat, but all methods to REMOVE heat are slow. They all rely on foods and drinks to BECOME cold based on the ambient temperature inside of the unit, rather than more direct methods like, for example, spraying a mug of ale with liquid nitrogen. Which would work great, but would be horribly dangerous to trust to the public.

dry ice in water will simulate a boiling effect as the ICE returns to gas .If you are camping in an ice region a can of sterno and calapseable stove wont melt ice and an aluminum pan heats water very fast and efficiently .but if I am not hitting the mark it's due to the lack of info in the querry given .

Ice and Ibuprofen. Make sure you don't put heat on it.

Can you melt that ice with a blow dryer?

u know that ice is H20 right? but that's not enough. it would easily melt if that's pure ice. so there is a Salt there. NaCl. why? because water or an ice slowly melts when thre is a substance. and vice versa when the water boils with salt.

My friend did one that answered the question : "Which melts ice faster: Salt or spices?"\n\nShe experimented with salt and spices like cinnimon, peprika, chili powder, red pepper...\n\nIt was pretty cool. The title we came up with was "Salt or Spice Melts the Ice?" \n\nSalt melted it the fastest.

Sorry I'm the kind of teacher you parents despair of because thats the kind of home work I'd set.  My class have to design and make a thermal insulator to stop ice melting this week!!!\n\nTry this link it might help\nhttp://www.volcanolive.com/model.html

You must add the ice 83.500 Kj of heat to melt it.

put a heating pad on it, or use icy hot.

Making ice cream is just a matter of freezing the mixture.  You use a mixture of ice and salt (because it has a lower temperature than just ice) to remove heat from the ice cream mixture. So, the ice cream mixture loses heat until it reaches its freezing/melting point, and then continues to lose heat until it is the same temperature as the ice/salt mixture.  That mixture gains heat from the ice cream mixture, and the ice melts, dissolving the ice.\n\nHope this helps...

Ice freezes and melts at 0 deg Celcius, ice water at about -18 degrees.\n\nWhen ice melts, it goes from ice at 0 deg to water at 0 deg. In the process, absorbs 80 calories of heat per gram of ice. This is known as heat of fusion.\n\nIf you have ice in water, all at 0 deg, there is an equilibrium formed where some of the ice is melting absorbing heat of fusion from the water, and some of the water is freezing giving heat back to the ice. \n\nWhen you add salt to the mixture, the freezing point of the water is depressed below 0, so the heat absorbed from water causes it to cool below 0 rather than being refrozen into ice.

it is possible but u can't eat it.\nas u may know that when pressure applied on any matter it's melting point increases and by applling very high pressure we can mantain icecream at high temp. but it is not possible practically\nif u want to eat hot ice cream then take ice cream melt it add suger, butter and skim milk powder to eat and heat a little and make a pasty substance which will taste u like a icecream which is hot

They use a fine mist spray and build the ice up a fraction of an inch at a time.  It is time consuming but works really well.

Use dry ice. It is always -78 or colder.

Please see the following dry ice website.\n\nPS - I am a licensed Professional Engineer.  I reviewed the following website and found the information quite adequate.  If you need additional information you just may need to do some work.
