convection Du!!!!!!!!!!!! .......
Conduction
It is because the heat is driven out of your hand. That's the simplest I can put it.
Francium melts at about 80oF. Cesium melts at about 83.4oF. Gallium melts at about 85.6oF. All of these are solid at room temperature but would melt in your hand. Rubidium melts at about 103.4oF, so that is just a little higher than body temperature. Mercury melts at 37.7oF, so it would certainly melt in your hand, but it would already be a liquid at room temperature.
This type of heat transfer is called conduction. The transfer is from the warm hand to cool water.
an example for threshing
The transfer of heat from cup to hand is known as conduction.

That is conduction

you make a snowball out of snow. hold in your hand, and throw the snowball
The snowball was cold in my hand.

It forms a liquid! Gallium the metal that melts in your hand!
An ice cube held in a hand begins to melt
Slapping someone in the face. Which cause energy from your hand to that persons face.
it melts in your hand because your hand has heat causing the chocolate to melt.
