No, as it freezes it loses energy, giving it off as 'latent heat'. This effect can be used in an outdoor shed when you fear a frost. If you put a load of buckets of water in the shed, then if there is a frost at night, the water will give out heat as it freezes, keeping the ambient temperature at 0 degrees Centigrade until all the water is frozen, which might be long enough to prevent the frost from freezing other things - jars of pickles for instance, which freeze at a slightly lower temperature.
It does. It requires quite a lot of energy to melt ice. It should be noted that the temperature of the ice/water mix doesn't increase while heat is being added - it remains at about 0°C. The heat is used to melt the ice, not to increase the temperature.
by boiling the water or putting it in the sun
Actually, it releases a little.
It takes in energy.
Freezing is an exothermic change.
The name for solid water is ice. It changes to a liquid when it melts.
Phase changes requiring the addition of heat energy are the phase changes from solid to liquid, liquid to gas, and solid to gas. These phase changes are termed melting (solid to liquid), evaporation (liquid to gas), and sublimation (solid to gas).
Condensation, which changes vapor to liquid water, and freezing, which changes liquid water to solid ice.
They can;liquid to gas= evapouration(boiling water)liquid to solid=freezing(ice cubes)gas to liquid= condensation(steamy bathroom windows)solid to liquid= melting(ice cubes).
the water looses energy to become solid (freezing). This happens due to electrons (which transfer and store the energy) going to a lower state where the atoms get closer together. Therefore ice takes up a smaller volume than when it is in a liquid state.
true, when ice changes to a liquid it asorbs heat energy .
It must flow out, ice contains less energy than water. You just have to remember that heat is energy, and all energy, no matter what form, eventually winds up as heat. Take heat energy out of water, it gets cooler, and eventually freezes. Add heat energy to ice, it first changes state to liquid, and then starts to get warmer. Keep adding heat energy to it, it keeps getting warmer and warmer. Keep additing heat energy to it, and eventually it changes state to gas ... called "steam". Take heat energy out of the steam, it first changes state to liquid, then gets cooler. etc. etc.
its a physical changes the particles in the ice cream do not move cause its a liquid
melting and from a solid to gas ,as in dry ice, it is sublimating
ice, it melts
When a gas changes to a liquid, it goes through the process of Condensation. This is when the gas cools and loses energy. Then the particles are forced to change state, from a gas to a liquid.

for example ice is melted down into a liquid
