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.
Melting of ice cubes is actually an endothermic process because energy is required to break the bonds between water molecules in the solid state and convert them into liquid water. Heat is absorbed from the surroundings during this phase change, causing the temperature of the ice to increase until it fully melts.
Any endothermic reaction, for instance photosynthesis.
be an endothermic reaction. This means that the products have more energy than the reactants. Examples include photosynthesis and the melting of ice.
Endothermic reactions are chemical reactions that absorb free energy, typically in the form of heat. These reactions require an input of energy to proceed. Examples include photosynthesis and the melting of ice.
Yes, adding salt to ice is an endothermic reaction because it absorbs heat from the surroundings in order to melt the ice. The process of dissolving salt in water requires energy, which is taken from the surroundings, resulting in a decrease in temperature.
No. It is a physical change.

Melting ice
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.

No, it is a physical change, not a chemical reaction.
Yes, the melting of ice cubes in a soda cup is an endothermic change. When ice melts, it absorbs heat from the surrounding liquid, which is the soda in this case. This absorption of heat causes the temperature of the soda to drop as the ice transforms from solid to liquid. Thus, the process of melting ice is characterized by the absorption of energy.
Ice cream production is an exothermic process because heat is released when the cream and sugar mix is churned and freezes. The freezing process of the mixture releases heat, making it an exothermic reaction.
