Heat is the flow of thermal energy from one object to another. Heat always moves from warm objects to cool objects, not cool objects to warm objects.
Thermal energy is transferred from a hot drink to an ice cube by conduction, where heat moves through direct contact between the hot drink and the ice cube. The heat from the hot drink causes the ice cube to melt as the thermal energy is transferred.
Some flows into your hands by conduction, some is lost to the surrounding air by convection
Thermal energy would flow from the hot drink to your hand, as heat always moves from a warmer object to a cooler one. Thus, the cup's heat would transfer to your hand, making it feel warm.
Heat flows from hot to cold.
Yes, heat flows from hot to cold.

The answer depends on where the ice cube is in relation to the stove: it could be conduction, convection or radiation.
Heat flows from hot to cold in a system.
From cold to hot.
Foam - styrofoam is an excellent insulator. With a hot drink - you want it to remain hot - so you do NOT want heat to move out of the drink to the cooler outside. The styrofoam vastly reduces this heat flow. With a cold drink, the reverse is true. You want it to remain cold so you do not want heat to move from your hand or the outside atmosphere into the drink. The styrofoam vastly reduces this heat flow.
As you drink hot cocoa, the heat from the cocoa transfers to your hands and then to your body. This is an example of heat energy transfer through conduction.
The heat spots on the table are located in areas where hot objects have been placed, such as near a hot dish or a hot drink.
Because a teaspoon is metal so the heat travels through it.
