I don't think that is possible. How can "hot" make "cool" water "cold"? (also, 'hot ice' is boiling water)
yes, hot water just cools down cold water will turn into ice which will take longer
The fastest way to cool hot water is to place the cup in a bowl of ice water or use an ice bath. Stirring the water will also help distribute the heat more evenly and speed up the cooling process.
You should wash it under cool water and then put ice.
There a range of things you can make water into. One is ice, another is steam. Ice will cool you on a hot day, steam will warm you on a cold day.
putting ice into water: the ice and water are in contact with each other over a large surface area this allows more efficient heat transfer. putting a bucket of water into ice: Energy in the form of heat must pass through the bucket to the ice which is more difficult. Also the is less contact area with the solid ice sitting against the bucket than if water was in contact with the bucket. This is why when u make an ice bath to cool something down in you add water, it increases the contact area.
The plastic cups I can get have thin walls. This means the water without ice stays as water because any temperature changes to the water will not last very long. Insulated cups have thick walls so they will cool liquids cool and hot liquids hot
You would cool a bucket by putting ice into the water.
salt ice water
Put ice in it
ice melts faster in hot water because the hot water is transfering the separate particles in hot
Yes. You can boil a mixture of sodium acetate in water and subsequently cool it. If you cause it to precipitate, it will feel hot.
