No. The phase change requires adding heat, so melting ice cubes is an endothermic reaction.
False
Endo draws heat from around it. Exo gives off heat. Example: Ice melting is a endothermic reaction. A match lighting is an exothermic reaction.An exothermic reaction releases heat to it's surroundings. The change in energy is negative. An example is combustion of natural gas.An endothermic reaction absorbs heat, so the temperature of the surroundings drops. The energy is positive. An example is melting ice cubes.
I don't know work it out!
Sugar has very little effect on melting point - it is too high molecular weight. That might answer your question, which does not make sense as written. Thus, it melts faster with sugar, because other ice cubes slow melting.
its called melting.
Exothermic reactions release energy, it often produces an increase in temperature, and in this reaction, the bonds energies of the reactants are less then the energies of the products (meaning it is greater when it is on the reactant side).
No, it is a physical change, not a chemical reaction.
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
exothermic. the energy flows out. exothermic. the energy flows out.
Some examples of exothermic reactions are melting ice cubes, water evaporation, and baking bread. An endothermic reaction occurs when heat is absorbed from the surrounding.
False.The original answer (now deleted ) said that the melting of ice is an endothermic reaction.If you need to convince yourself of this, take half a glass of water at room temperature. Put in a thermometer, wait a while, then record the temperature.Now add a few ice cubes; wait a while, then check the temperature again. If the melting of ice were an exothermic process, the water would then be warmer. Since you will actually find the water to be cooler, it is an endothermic process.
ice melting is a physical reaction
sawdust
No, it's a physical action. No chemicals change into any other chemicals.
yes.
Ice cubes explode in a drink because they are melting at a fast rate. The ice cannot contract fast enough to keep up with the melting, which causes it to crack.

Yes. Salt, for example, will speed up the melting of ice cubes.
