Why must heat be supplied to melt ice after all the temperature does not change?

The temperature must heighten for ice to melt. The melting point of ice/water is about 0 degrees Celsius.
---------------------------------------------------------------------------------------------
Suppose we are at 1 atmosphere and we want to melt an ice cube (of pure water)
that is at -5oC. We give heat to the ice cube (hypothetically at very slow rate so we warm the ice cube in a homogeneous fashion). The temperature of the ice cube will rise to 00C before it starts to melt. During the melting process the heat given to the ice is invested in braking the intermolecular bonds. This is called the latent heat of fusion or
fusion enthalpy. Not until the ice completely melts, the temperature will start going up again.

What temperature of water is best for ice cube melt faster?
If Ice cubes are melting in water, the temperature of both the ice cubes and the water will be exactly the freezing temperature of water: 32F, 0C. You cannot change this. You can add heat to make the ice cubes melt faster, but the extra heat will have no effect on the temperature, It will all go to melting the ice cubes.
Will ice melt faster with heat?
yes it will, if it is warmer then the current temperature
Why is energy needed to melt ice?
Heat is hotness and when ice has hotness in the surroundings, it will changes its temperature to fit in with the room temperatute, therefore ice will change its state
What is the definition for latent heat of melting?
The amount of heat released / absorbed from a substance at constant temperature as you change state from liquid->solid / solid->liquid.
How much ice melts?
Under standard atmospheric conditions it just needs a temperature above 0˚C and time. If you have a defined mass or ice and external temperature you could find the time required to melt the ice. what may also help is that the latent heat of fusion for water ( the energy required to melt ice) is 334 kJ/kg so if you times that by your mass in kg you will find the energy needed to melt the amount of ice you have.
When heat is supplied to a solid substance?
In that case, the solid substance will either increase in temperature, or it will melt. Some substances may also sublimate instead of melting - this means that they change directly to gas form.
What temperature does ice melt fastest?
Cold water will not melt the ice cube in record time, but hot water will, but salt water will also melt it fast, but if you add both together the ice cube will melt alot fast. Deceasing time alot.
Why do the ice cubes melt when the temperature rises?
They melt because the heat in the air is warmer than the temperature of the ice cubes.
What happens to the temperature when matter changes state?
Quite often, the temperature doesn't change. For example: if you melt ice, you convert ice at 0 °C to water at 0°C. You need to put heat energy into the ice to melt it, but its temperature doesn't change. (The change of state itself requires energy - this is a type of potential energy.)

How to melt cement?
heat it up, probably to a pretty high temperature.
Will ice melt faster with heat?
yes it will, if it is warmer then the current temperature
How a solid change into a liquid?
Many solids will change into liquids if you heat them, for instance most metals will melt when subjected to heat, ice will become water when heated, some plastics will melt, glass will melt, and most rocks will also melt.
To change from solid to liquid because of the heat?
melt
What are the conversions that take place when heat is supplied?
IF no chemical reaction takes place, heat a solid to melt it, converts it to a liquid (melting). More heat raises the temperature until it boils, converts the liquid to a gas (vaporization). Some substances can be heated and converted directly from asolid to a gas, (sublimation).
How do you calculate the amount heat required to change 5 pounds of ice at 32 degree to water at 32 degree?
80 calories of heat are required to melt one gram of ice without altering the temperature. There are 2267.96 grams in five pounds so you would need 181436.8 calories of heat to melt all that ice without raising the temperature.
Why is energy needed to melt ice?
Heat is hotness and when ice has hotness in the surroundings, it will changes its temperature to fit in with the room temperatute, therefore ice will change its state
