Why does it usually take long for an ice cube to melt?

Answer 1

There are a few factors as to why an ice cube takes its time in melting. The main factors are the size of the ice and the temperature of its surroundings. The larger the piece of ice, the longer it takes to melt. This is because the ice itself is very cold and it takes a while for the temperature to completely melt the whole cube. If it is very small, it is subject to faster melting because the temperature melts the small amount of water easier. The other main factor is the temperature, the closer the temperature is to 0° C, the faster it will melt. There are also other factors like the other contents of the cube, time spent in and out of cold area and even air pressure but those seem irrelevant to this specific answer. Assuming this ice cube is normal sized in room temperature, the reason for the long time would be the fact that the room is around 60-70° F and it takes a while for the ice cube to adjust to the temperature and be affected by it. Once the high temperature of the room act on the below freezing ice cube, they will raise the ice cube's temperature to 0° C and it fully melts.

Other Answer:

It depends on how big the ice cube is and on the temperature in the room or out side. for example: If i have an ice cube and i set it out side in the snow it will melt it will just take longer because its very cold out side. Or..... If i have an ice cube and i set it in 90 degree weather it will melt a lot faster than in the snow.

Answer 2

Ice cubes take a long time to melt because the process of melting requires heat energy to break the bonds holding the water molecules in a solid state. The difference in temperature between the ice cube and its surroundings also plays a role in how quickly it melts.

Answer 3

because its cold plus cold but if it was hot plus cold it would melt alot faster

Answer 4

Yes. Milk is cold and ice is cold. You have to have warm milk and cold ice toile ice melt faster.
