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.

Is cold pack exothermic or endothermic?
Endothermic- a change in which energy is taken in. The melting of ice is an endothermic change. Ice absorbs thermal energy from its surroundings when it melts. That's why you pack drinks and food in an ice-filled picnic cooler to keep them cold. So yes an ice cube is endothermic.
What are some physical endothermic phenomenons?
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.
Is ice melting a physical or chemical reaction?
Physical
How is melting ice a physical reaction?
it is certainly not a chemical reaction, and it is still melting something, so it is a physical reaction. it does depend HOW you melt it, but other than that, it is a physical reaction.
Is a melting ice lolly a chemical reaction?
No ice- cream melting is not a chemical reaction, because with a chemical reaction it is hard to get back the original form. But with ice cream melting that is a physical change because you can easily freeze the ice cream again and get it back to normal un-melted ice cream.
Which reaction is an endothermic reaction?
Melting ice
How does melting of ice produce cooling effect?
because it is an endothermic reaction.
The melting of ice cubes is an exothermic reaction?
No. The phase change requires adding heat, so melting ice cubes is an endothermic reaction.
What is the melting of ice?
Scientifically it is an endothermic reaction. Where ice absorbs surrounding heat to form a liquid.
Is melting ice endothermic or exothermic change?
Ice cream melting (or pretty much anything melting) is an endothermic process in that it requires the absorption of heat energy in order to occur. An example of an exothermic process is the burning of paper which gives off heat energy.
Is ice melting chemical reaction?
ice melting is a physical reaction

Is it an endothermic reaction if salt is added to ice?
Define endothermic....
What are some physical endothermic phenomenons?
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.
Which process describes the melting of ice cream?
Endothermic
During which change is energy absorbed?
the melting of ice
What chemical reaction that absorbs heat called?
Endothermic reactionFor endothermic reactions Hfinal > Hinitial and DH is positive (+DH)It can be for example melting ice, or vaporising Rubbing Alcohol.---------Change of phases are not chemical reactions !
