We regard liquid and gases as fluid because they they have very less or almost negligible force of attraction and very large intermolecular spaces and hence they can flow in any direction. Same is the reason of its fluid nature.
Hi!
First of all, the melting of ice cream is not a chemical reaction, because there is no change in the components of the ice cream and if you freeze the ice cream again, you will get the same ice cream that you had previously.
The melting of ice cream is an example of a physical change, in which a substance goes from solid to liquid state, and it is an endothermic physical change.
When you freeze ice cream, the heat is removed from the ice cream, making it an exothermic process, when heat is liberated to the environment and it's taken away from the substance, in this case, the ice cream.

An ionic bond is an attraction between ions of opposite charge in an ionic compound.

Answer:
Dissolving is when the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules. This break up is caused by coming into contact with the solvent. In the case of salt water, the water molecules break off salt molecules from the larger crystal lattice.
