Kinetic energy of the molecules in the drink decreases.
Faster-moving molecules, within the hotter object, slower-moving molecules, in the colder object.

Kinetic energy of molecules decrease. True.
Evaporation of the water increases. False, it is the other way.
3 Kcal of hat is transferred into the drink. Heat transfer is the other way and if Kilo is meant, then a capital K is used.
Molecular collisions in the drink increase. Dunno for sure.
