I have no idea and have been asked this question, thanks in advance for the answer.

Oh... then it's a totally different question!James Leighe said:The real question is why is it that hot water will make ice-cubes faster than cold water...

mgb_phys said:All else being equal the rate of cooling depend son the temperature difference between the water and it's surroundings - so unless it's very cold in your kitchen, the fridge would be better.

Putting the hot water in the fridge will cause it to cool down and reach the same temperature as the fridge, which is typically around 4 degrees Celsius. This process is known as thermal equilibrium.
Yes, the water in the fridge will cool faster than the one left outside. This is because the fridge is a closed environment with a lower temperature, allowing for faster heat transfer between the water and the surrounding air.
The time it takes for the water to cool in the fridge depends on various factors such as the initial temperature of the water, the temperature of the fridge, and the volume of water. Generally, it can take anywhere from 30 minutes to a few hours for the water to cool down.
The hot water in the fridge does not turn into ice. It simply cools down and reaches the same temperature as the fridge, which may make it feel like ice in comparison to the room temperature water. The freezing point of water is 0 degrees Celsius, which is much lower than the temperature of a typical fridge.
Yes, you can drink the water that has been in the fridge. As long as the water was clean and safe to drink before it was put in the fridge, it will still be safe to drink after it has been cooled down. However, if the water was left in the fridge for an extended period of time and has developed a strange odor or taste, it is best to discard it.
