why does an ice cube take longer to melt when placed in liquid?

Answer 1

The reason for this is the difference in temperature between the ice and the liquid. When something cools, it follows a path similar to the curve of an exponential function. This means that the rate of cooling is faster at higher temperature differences and slower at lower temperature differences. The temperature of the liquid is cooler than that of the air, so it takes longer.

Answer 2

Because the odds are that the liquid is a colder temperature than the room it's in. Even if your soda (or whatever drink) is not cold to your touch, it's probably colder than the current room temp.

Now if you took an ice cube and dropped it in some hot coffee (which is normally hotter than the room temp), the ice cube would melt quicker than it would if you had just set the ice cube on the counter and watched it melt.

Answer 3

Everyone knows that it takes longer to malt in colder temperatures, right, well...

In the air, by the way, air is gas, rapid moving gas particles give off energy. Temperature, is actually a measure of kinetic energy. So, as the ice cube is surrounded by air, the air's gas particles bombard it giving energy, and thus increasing its temperature. As this increases, it melts faster.

In a liquid, the ice cube is pushed around by slowlier (slowlier isn't really a word) moving particles. Since the particles of a liquid move slower, they don't increase the temperature as much, and thus making it melt slower.

So, in conclusion, particles of a liquid keep the ice cube at a lower temp, so it doesn't melt as fast. Particles of the gas in the air bombard the ice cube and give off energy, making it melt faster.

Answer 4

Ice melts due to the transfer of temprature from one medium to another so the temperature transfer rate is what determines the length of time that the cube will take to melt. As the transfer time from solid ice to gaseous air is faster then the transfer rate from solid ice to liquid water, it will take longer for ice to melt in water(or other liquids) then it does in air.

Answer 5

thermodynamics
the heat transfer from one object to another.
you will see that tile and aluminum are very good heat conductors, (they will heat up, but cool off very quickly)
Water on the other hand will hold it temperature.

so an ice cube put in a water based liquid will stay an ice cube longer than equal temperature non water based liquids theoretically.

Answer 6

That depends on a number of factors.
For the situation described I would say that the ice brings the liquid to an equilibrium temperature which would bring convection currents to a minimum; slowing the heat transfer to the cube.
Convection is usually the dominant heat transfer mechanism.

Answer 7

one million) the quantity of ice is 4 * one million * one million *one million = 4 cubic inches Density of ice is 0.917 g/cm^3 and all of us know the density of water is 1g/cm^3 And while the ice melts it is going to transform to water so shall we decide the quantity of water which would be extra 4 cu in * 0.917/one million = 3.668 cu in i'm doing this because of the fact I already know the answer to #2, is that the point will staty the comparable. So we are cheating a splash and making use of that. in case you upload this quantity you will advance the filling intensity. the area to be filled is 3" x 3" = 9 squareinches so the top it is going to upward push is 3.668 cu in/ 9 squareinches = 0.408" so as this is the top replace up # 2 is an user-friendly one, the point would not replace. The decrease density of the cubes motives them to glide yet nonetheless displace water equivalent to their weight. So while they soften it does no longer something

Answer 8

when ice cubes melt they are really giving off their heat to the objects arround them. liquids dont receive heat as quick as air.

Answer 9

all depends on the liquid and tempurature!
