Freezing of ice cream is Exothermic, Because you must remove heat from the ice cream to freeze it. The Heat flow is negative when the ice cream is your system, you are moving the heat from the ice to the surroundings most likely a freezer. This is how a Freezer cools items it does not add cold (there is no such thing just heat) it removes heat from the item inside and convects it on to its self and eventually to the air, so the freezer is endothermic.
An exothermic reaction is one that gives out heat when the component parts are combined, for example - mixing water and plaster of Paris or water and caustic soda.
When you mix the ingredients for cookies or a cake the mixing bowl does not get hot. You need to place the product into a heated oven in order to turn the mixture into a cake or cookies. The ingredients absorb the heat energy and chemical changes take place - the toughening of protein, sugar and fat changing from solid to liquid, baking powder releasing carbon dioxide and so on. Therefore baking is an example of an endothermic reaction.

Is the process of celular respiration exothemic or endothermic explain your answer?
exothermic
Is endothermic melting or freezing?
Melting is endothermic. Freezing is exothermic.
Is melting process a endothermic and exothermic?
endothermic
Is melting an exothermic or an endothermic process?
It is an endothermic process.
Is melting ice endothermic or exothermic change?
Melting ice is an endothermic process because it requires heat energy to break the bonds between the water molecules in the solid ice structure to form liquid water. This absorbs energy from the surroundings, making it endothermic.
Which reaction is an endothermic reaction?
Melting ice
What is a good name for chocolate melting?
melting chocolate is a good name. it depends if you are talking about what it is called after melting or while it is melting.
What are the phase changes that are endothermic?
For example melting or boiling.
Which process describes the melting of ice cream?
Endothermic
Which state changes are exothermic and endothermic?
Exothermic state changes release heat energy to the surroundings, such as freezing and condensation. Endothermic state changes absorb heat energy from the surroundings, like melting and vaporization.
What are some similarities of melting and boiling water?
Both are endothermic.
When a solid melts why does it need energy?
Melting is an endothermic process.
