it makes it taste better and it is cold
since there is kinetic energy in both hot and cold objects the particle in the hot objects move fast causing heat and the particles in the cold object move slower so the cold kinetic energy can cause the hot kinetic to become cooler in other words When you pour cold milk into hot cocoa the milk and cocoa particles start to collide. When a high-energy cocoa particle hits a low-energy milk particle, energy transfers. The cocoa particles slow down and the cup of cocoa cools down.
I believe you are asking 'is hot cocoa better hot or cold'. If you make 'hot cocoa' with cold milk the cocoa will not dissolve and you will end up with lumpy not very well mixed chocolate milk.

The milk becomes cocoa flavoured.
The cocoa powder is the solute, and the milk is the solvent.- - - - -Cocoa powder doesn't dissolve in milk. It forms a "suspension." The milk is a carrier.
Not necessarily. White Chocolate is made by using cocoa butter but not the cocoa solids. There is milk in it, but more sugar is added to make up the bulk. Dark chocolate can be either milk chocolate (chocolate made with milk, but with cocoa solids as well as cocoa butter) or plain chcocolate (chocolate made with cocoa solids and cocoa butter but without milk). If you add white chocolate to milk chocolate then the result will be a very sweet milk chocolate. If you add white chocolate to plain chocolate, the result will be a milk chocolate
Powdered Cocoa is a powder made from cacao seeds after they have been fermented, roasted, shelled, ground, and freed of most of their fat. It is used mostly in baking and making fudge, but can be used to make hot chocolate. Cocoa Mix is this mixture of cocoa powder, dry milk and sugar. It is combined with cold or boiling water to make a cold or hot, chocolate-flavored beverage.
Thick curd produces body heat after consuming. Butter Milk cools your body.

Hot cocoa is warmed up to a higher temperature (due to solubility reasons). Milk is chilled and stored in the refrigerator.
Common chocolate drinks are chocolate milk and hot chocolate. Chocolate milk is a mixture of milk, cocoa powder and sugar, served cold. Hot chocolate is either hot chocolate milk or solid chocolate melted in milk.
Erasto B. Mpemba was a scientist from Tanzania who discovered that warm milk cools faster than cold milk while doing an experiment with his classmates.
