When you hold a snowball in your hands, the heat energy produced by your hands is transferred into the fusion of ice to water. Fusion is an endothermic reaction.
Some of it is though you also get convection an conduction heat transfer
Heat Energy
Conduction heat transfer refers to the process of heat transfer between two objects or regions in direct contact with each other. This transfer occurs due to the collision and transfer of energy between the molecules of the objects. It relies on the physical contact and proximity of the objects for heat to be conducted from the hotter object to the cooler one.
do not transfer heat very well.

A fireplace heats a room by radiation. That radiation is the direct transfer of energy by electromagnetic waves.

Heat Energy
This heat transfer happens by convection.
It's cold winter day. You've been out playing and you warm your handds by your fireplace.
Conduction heat transfer refers to the process of heat transfer between two objects or regions in direct contact with each other. This transfer occurs due to the collision and transfer of energy between the molecules of the objects.

Conduction is heat transfer WITHOUT matter transfer Convection is heat transfer WITH matter transfer

Yes. This often happens with friction. For example, if you rub your hands together, you can feel the heat.
millions of tiny gnomes hold hands blocking the transfer of heat or lack there of
The fireplace's heat is an example of radiation.
