# How Long Does It Take For An Ice Cube To Melt At Room Temperature?

Actually, it takes about 30 to 45 minutes to melt completely.
thanked the writer.
The time it takes to melt depends on the size of the cube, the actual temperature of the room and the original temperature of the ice. Other factors should be considered to a lesser degree.

A large cube will take longer to melt because it must absorb more heat to completely melt then a small cube.

Room temperature can be 68 to 80 degrees depending on how warm you like the room. At 80 degrees the ice will melt faster then at 68.

Water freezes at 32 degs F, but you can chill ice to an even colder temperature after it is frozen.
-10 degree ice will take longer to melt then +30 degree ice.

The ice cube I have (+20 degrees, 1 cubic inches, at 75 degree room temp) took about 12 mins. To melt. Your results will vary.

Exactly

Well, it depends on 2 things - they are the room temperature and the size, or how cold the cube was. But on average it takes about 10-20 mins to melt as ice cubes can be really affected by the room's temperature.

Mine took 86 mins, which is the same as 1 hour 26 mins. It was in a room and not in water and I used a stopwatch. The exact time was 01:26:53.95

there is any formula for melting time please provide me

I did 3 ice cubes and they were in different rooms with different temperatures. They all took around 20, 27, 30 minutes to melt.

It takes about 14 minutes because of what shape and size it is.

Half an hour.

The heat makes the water particles(in the ice cube) change state.

It's around 4 minutes.

We know from the first law of thermodynamics that heat always flows from high to low temperatures.

So in this case, the ice cube has a temperature below 0 c and room temperature may be up to 22c or 24.

So, in this case, heat will flow to the ice cube and melt it down.
