put it in the freezer ;)
It insulates it, keeping the cool in and the heat out.
Due to their varying melting points (ice 32 and sugar 366°)
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
Sawdust can help insulate the ice cube and slow down the melting process, but it won't completely prevent the ice cube from melting. The insulating properties of the sawdust reduce the transfer of heat to the ice cube, which can help keep it colder for longer.
Cotton balls will not keep an ice cube from melting. While they may insulate the ice cube slightly, they are not effective at preventing the ice from melting due to their low heat conductivity. Placing the ice cube in a well-insulated container or using a more effective insulating material would be more effective in preventing the ice from melting.
UV light can contribute to the melting of an ice cube by transferring energy to the ice cube, causing it to absorb the energy and melt faster. The UV light can increase the temperature of the ice cube, accelerating the melting process compared to no exposure to UV light.
Melting of ice is at 0 oC.
Temperature affects an ice cube by either melting it or freezing it. If the temperature is warmer than the ice cube's melting point, the ice will melt into water. If the temperature is colder than the ice cube's freezing point, the water will freeze and the ice cube will grow.
Because the melting temperature of the ice is 32°F and the melting temperature of the salt is 1,474°F.
Melting
To keep an ice cube from melting for up to 8 hours, you can store it in a well-insulated cooler with additional ice packs or dry ice. Keeping the cooler closed as much as possible will also help maintain the ice cube's temperature. Alternatively, you can wrap the ice cube in a thick layer of newspaper or aluminum foil to insulate it further.
store the ice in a cool storing place
