No. The phase change requires adding heat, so melting ice cubes is an endothermic reaction.
Any endothermic reaction, for instance photosynthesis.
No, although it may seem counter intuitive, freezing is an exothermic process. In order to go from a liquid to a solid phase a substance must lose energy. This energy is released to the surroundings.
Lemon does not have any unique properties that would help melt ice cubes faster. The primary method for melting ice cubes is through heat transfer, which can be achieved by using warm water or placing the ice cubes in a warmer environment.
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.
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.
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.

ice melting is a physical reaction
No, the melting of ice cubes into water is a physical change, not a chemical reaction. A chemical reaction involves the breaking and forming of chemical bonds to create new substances, whereas melting is a phase change where the substance transitions between solid and liquid states without altering its chemical composition.
To prevent ice cubes from melting quickly, you can use an insulated cooler or container to keep them cold for longer periods. Additionally, you can add salt to the ice to lower its melting point, or use dry ice as a colder alternative. Placing the ice cubes in the freezer until needed can also help delay melting.
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 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.
Yes. Salt, for example, will speed up the melting of ice cubes.
